Aims: The study aims to develop advanced antibacterial agents as nanoparticles instead of antibiotics due to the emergence of antimicrobial resistance. Background: Pseudomonas aeruginosa is capable of causing many diseases, including severe bacterial pneumonia. There is a need for an efficient antibacterial agent to kill these pathogens. Objective: The objective of the study is to synthesize advanced antibacterial agents as nanoparticles for biomedical applications that can play a vital role in killing Gram-negative bacteria (Pseudomonas aeruginosa). Method: A novel fabricated growth of hydrophilic spiky gold nanoparticles (SGNPs) via reduction method is reported. Results: The surface plasmon resonance peak of the synthesized SGNPs was tuned under the near-infrared range. The SGNPs have anisotropic and spiky morphology with 68 nm size and -58 mV surface charge. They are pure, possessing adsorption similar to the organic material. Pseudomonas aeruginosa treated with synthesized SGNPs showed 60% bacterial death at the concentration of 100 μM. Conclusion: This work consists of the novel synthesis of SGNPs via a safe and simple reduction method. The synthesized SGNPs exhibit strong antibacterial activity against the Gram-negative bacteria Pseudomonas aeruginosa measured using a microplate assay test.

Nanoparticles range in size from 1-100 nm although much larger nanoparticles i.e. up to 300 nm, are widely reported for medical application. Current trends in drug delivery research have shifted focus toward the designing of the “smart” drug delivery systems (DDS) for spacial and temporal control of the drug delivery. When a magnetic moiety is added to a DDS i.e. nanoparticle or liposome, it can be retained in a specific part of the body through localized magnetic field. These magnetically modulated drug delivery systems (MDDS) can also carry payload to deep lying tumor tissues which are difficult to target with other targeting modalities. MDDS are also used as hyperthermic agents under the influence of externally applied alternating magnetic field. Not only the magnetic hyperthermia can kill cancer cells but also causes phase-change in nanoparticles to induce abrupt drug release. Magnetic resonance imaging (MRI) is a diagnostic techniques used to image disease specific changes in tissues using contrast agents such as iron oxide nanoparticles. When iron oxide nanoparticles are loaded with drugs, they act as a contrast agent and carrier for targeted drug delivery which is revolutionizing medical field. In addition to drug delivery applications, magnetic nanoparticles are also being used in biosensors for identification and separation of target molecules/cells from complex mixture. However, challenges associated with optimized particle size, selection of biocompatible materials, and fate of MDDS after in vivo application need to be addressed. Emerging literature also points towards interaction of magnetic field with human body. Thus, carefully tailored magnetic modulated nanoparticles are expected to emerge as a key player in medical field due to their unique diagnostic, therapeutic, sensing and multifunctional application.

The emerging pandemic situation has created unease and dismay at every level, from governing bodies to population and from pharmaceutical manufacturers to front-line servers. Everyone is scarified by the death-dealing and ruinous effects of COVID-19. The encouraging and positive news about vaccine development and successful trials of vaccine proved to be remedial, but another dilemma arises in the form of mutation of the deadly virus. Question marks are arising about the lethality of mutated strain, lack of management and protective measures by the governing bodies, and ambiguities are aroused about the effectiveness of vaccines against them. After an all-inclusive and particularized study and genomic examination of the virus, the researchers have put forward the details that Coronavirus Mutation is Worrying but Not Terrifying. The upshot is that it is required to screen, but at present, their mark suggests that the new strain in the UK is more transmissible but neither severe nor resistant.

Hyperthermia has become an important area of research for cancer treatment throughout the world. Choosing appropriate magnetic nanoparticles for specific performance at the cancerous site of the body is a major problem. In this research work, iron oxide nanoparticles were synthesized using laser ablation and Ag@α‑Fe2O3 and γ-Fe2O3 nanoparticles using chemical methods. The size and shape of synthesized nanoparticles were characterized by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). These nanoparticles were then exposed to the alternating magnetic field in a fluid medium in a calorimeter. The heat generated by nanoparticles in the response to the applied magnetic field due through Neel relaxation and through Brown relaxation effects was measured using an array of the k-type thermometer. Their thermal responses in AC magnetic field to time regarding their types were studied. γ-Fe2O3 produced more heat, sufficient enough to kill the cancer cells selectively.

The low aqueous solubility of many drugs reduces their bioavailability in the blood. Oils have been used for centuries to enhance the solubility of drugs; however, they can disturb the lipid profile of the patients. In this study, self-nanoemulsifying drug delivery systems of omega-3 fatty acids-rich oils are prepared and optimized for the delivery of lipophilic drugs. Rosuvastatin, a potent hypolipidemic drug, was used as a model lipophilic drug. Fish oil showed more than 7-fold higher solubility of rosuvastatin than other oils and therefore it was selected for the development of self-nanoemulsifying drug delivery systems (SNEDDS). Different combinations of surfactants and co-surfactants were screened and a surfactant mixture of Tween 80 (surfactant) and Capryol PGMC (cosurfactant) were selected for compatibility with fish oil and rosuvastatin. A pseudoternary phase diagram of oil, surfactant, and co-surfactant was designed to identify the emulsion region. The pseudoternary phase diagram predicted a 1:3 oil and surfactant mixture as the most stable ratio for the emulsion system. Then, a response-surface methodology (Box-Behnken design) was applied to calculate the optimal composition. After 17 runs, fish oil, Tween 80, and Capryol PGMC in proportions of 0.399, 0.67, and 0.17, respectively, were selected as the optimized formulation. The self-nanoemulsifying drug delivery systems showed excellent emulsification potential, robustness, stability, and drug release characteristics. In the drug release studies, SNEDDS released 100% of the payload in around 6 h whereas, release of the plain drug was less than 70% even after 12 h. Therefore, omega-3 fatty acids-rich healthy lipids have enormous potential to enhance the solubility of lipophilic drugs whereas, self-emulsification can be used as a simple and feasible approach to exploit this potential.

The severe life-threatening effects of systemic chemotherapy are well documented. Doxorubicin, DOX is the most effective antineoplastic agent but with the least specific action that is responsible for severe cardiotoxicity and myelosuppression that necessitates careful monitoring while administering. Stimuli-sensitive/intelligent drug delivery systems, specifically those utilizing temperature as an external stimulus to activate the release of encapsulated drugs, have become a subject of recent research. Thus, it would be ideal to have a nanocarrier comprising safe excipients and controllable drug release capacity to deliver the drug at a particular site to minimize unwanted and toxic effects of chemotherapeutics. We have developed a simple temperature-responsive nanocarrier based on eutectic mixture of fatty acids. This study aimed to develop, physicochemically characterize and investigate the biological safety of eutectic mixture of fatty acids as a novel construct for temperature-responsive drug release potential.Methods: We have developed phase change material, PCM, based on a series of eutectic mixtures of fatty acids due to their unique and attractive physicochemical characteristics such as safety, stability, cost-effectiveness, and ease of availability. The reversible solid-liquid phase transition of PCM is responsible to hold firm or actively release the encapsulated drug. The eutectic mixtures of fatty acids (stearic acid and myristic acid) along with liquid lipid (oleic acid) were prepared to exhibit a tunable thermoresponsive platform. Doxorubicin-loaded lipid nanocarriers were successfully developed with combined hot melt encapsulation (HME) and sonication method and characterized to achieve enhanced permeability and retention (EPR) effect-based solid tumor targeting in response to exogenous temperature stimulus. The cytotoxicity against melanoma cell lines and in vivo safety studies in albino rats was also carried out.Results: Doxorubicin-loaded lipid nanocarriers have a narrow size distribution (94.59– 219.3 nm), and a PDI (0.160– 0.479) as demonstrated by photon correlation microscopy and excellent colloidal stability (Z.P value: − 22.7 to − 32.0) was developed. Transmission electron microscopy revealed their spherical morphology and characteristics of a monodispersed system. A biphasic drug release pattern with a triggered drug release at 41°C and 43°C and a sustained drug release was observed at 37°C. The thermoresponsive cytotoxic potential was demonstrated in B16F10 cancer cell lines. Hemolysis assay and acute toxicity studies with drug-free and doxorubicin lipid nanocarrier formulations provided evidence for their non-toxic nature.Conclusion: We have successfully developed a temperature-responsive tunable platform with excellent biocompatibility and intelligent drug release potential. The formulation components being from natural sources present superior characteristics in terms of cost, compatibility with normal body cells, and adaptability to preparation methods. The reported preparation method is adapted to avoid complex chemical processes and the use of organic solvents. The lipid nanocarriers with tunable thermoresponsive characteristics are promising biocompatible drug delivery systems for improved localized delivery of chemotherapeutic agents.Graphical Abstract: Keywords: nanostructured lipid carriers, lipid nanocarriers, thermoresponsive, eutectic mixtures, fatty acids, phase change materials, doxorubicin, acute toxicity studies, hemolysis assay

Classical prodrug design is a sweeping approach to throw away futile side effects related to drug therapy. The main purpose of prodrug designing is to ameliorate physicochemical, pharmaceutical, and pharmacokinetic characteristics of particular compounds to resolve issues like formulation, delivery to the target site, and toxicity limitations. To fabricate the pharmacological action in CNS, drugs must cross the blood-brain barrier (BBB). Therefore, prodrug strategies are designed which include lipidization and the use of carriers and transporters. In this article, we have reviewed different anticancer, neuroprotective, and antiviral prodrugs. Flurbiprofen prodrugs, glycosylated prodrugs, resveratrol prodrugs, levodopa, etc., are mapped out for neurodegenerative disorders in CNS. Due to the poor oral pharmacokinetic properties of antiviral agents, drug design methods are performed by combining the parent drug molecule with a number of active components such as dipeptide esters, amino acids, nucleosides, and macromolecular-based prodrugs.

Increasing drift in antimicrobial therapy failure against Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), and the advent of extended resistant strains strongly demand discovery of mechanisms underlying development of drug resistance. The emergence of resistance against anti-TB drugs has reached an alarming level in various parts of the world, providing an active platform for the design of new targeted drug delivery. Reactive oxygen species (ROS) have an important role in controlling TB pathogenesis. At macrophage activation, ROS that are produced inside macrophages directly kill resident bacteria. These ROS possess a dual character because they can kill macrophages along with the resident bacteria. Targeting these ROS can play a remarkable part in overcoming resistance of conventional drugs. Nanoparticles (NPs) have evolved as a potential drug carrier for targeted delivery and elimination of various resistance mechanisms against antimicrobials. Receptor-mediated targeting of macrophages via different NPs may be a promising strategy for combating drug resistance and enhancing efficacy of old-fashioned antimycobacterial agents.

A multiple dose regimen is a concept that is used for certain diseases as arthritis, heart diseases etc. It is used to increase the therapeutic activity and clinical efficacy of the drugs. Drugs are usually used in single doses to produce acute effect but in cases where chronic affect is required multiple dosage regimen is required. Designing the dosage regimen and maintaining the drug concentration in blood plasma after administration are the primary goals to achieve safety and efficacy. That is to maintain drug concentration in therapeutic window. Moreover, the IV infusion and continuous IV diffusion is reviewed.

Docetaxel is relatively less hydrophobic and twice as potent as paclitaxel. Like other taxane chemotherapeutic agents, docetaxel is not well tolerated and shows toxicity in the patients. Nanoencapsulation of potent chemotherapeutic agents has been shown to improve tolerability and therapeutic outcome. Therefore, the present study was designed to fabricate chitosan and sodium tripolyphosphate (STPP) based on ionically cross-linked nanoparticles for sustained release of docetaxel.Methods: Nanoparticles were prepared by the ionic-gelation method by dropwise addition of the STPP solution into the chitosan solution in different ratios. CNPs were characterized for post-formulation parameters like size, zeta potential, scanning electron microscope (SEM), FTIR, DSC/TGA, pXRD, and in-vitro drug release, as well as for acute oral toxicity studies in Wistar rats.Results and discussion: The optimized docetaxel loaded polymeric nanoparticles were in the size range (172.6nm–479.65 nm), and zeta potential (30.45–35.95 mV) required to achieve enhanced permeation and retention effect. In addition, scanning electron microscopy revealed rough and porous surface, whereas, FTIR revealed the compatible polymeric nanoparticles. Likewise, the thermal stability was ensured through DSC and TG analysis, and powder X-ray diffraction analysis exhibited solid-state stability of the docetaxel loaded nanoparticles. The in-vitro drug release evaluation in phosphate buffer saline (pH 7.4) showed sustained release pattern, i.e. 51.57–69.93% within 24 hrs. The data were fitted to different release kinetic models which showed Fickian diffusion as a predominant release mechanism (R2= 0.9734–0.9786, n= 0.264–0.340). Acceptable tolerability was exhibited by acute oral toxicity in rabbits and no abnormality was noted in growth, behavior, blood biochemistry or histology and function of vital organs.Conclusion: Ionically cross-linked chitosan nanoparticles are non-toxic and biocompatible drug delivery systems for sustained release of chemotherapeutic agents, such as docetaxel.Keywords: tripolyphosphate, ionic gelation, sustained release, targeting, biocompatible, biodegradable

Nanotheranostics is an emerging frontier of personalized medicine research particularly for cancer, which is the second leading cause of death. Supramolecular aspects in theranostics are quite allured to achieve more regulation and controlled features. Supramolecular nanotheranostics architecture is focused on engineering of modular supramolecular assemblies benefitting from their mutable and stimuli-responsive properties which confer an ultimate potential for the fabrication of unified innovative nanomedicines with controlled features. Amalgamation of supramolecular approaches to nano-based features further equip the potential of designing novel approaches to overcome limitations seen by the conventional theranostic strategies, for curing even the lethal diseases and endowing personalized therapeutics with optimistic prognosis, endorsing their clinical translation. Among many potential nanocarriers for theranostics, lipid nanoparticles (LNPs) have shown various promising advances in theranostics and their formulation can be tailored for several applications. Despite the great advancement in cancer nanotheranostics, there are still many challenges that need to be highlighted to fill the literature gap. For this purpose, herein, we have presented a systematic overview on the subject and proposed LNPs as the potential material to manage cancer via non-invasive approaches by highlighting the use of supramolecular approaches to make them robust for cancer theranostics.

Hematology tests, considered as an initial step in patient diagnostic process, require laboratory equipment and technicians which is a time and labor-consuming procedure. Such facilities may be available in a few central laboratories in under-resourced countries. The growing need for low cost and rapid diagnostic tests contributes to point-of-care (POC) medical diagnostic devices providing convenient and rapid test tools particularly in areas with limited medical resources. In the present study, a comprehensive numerical simulation of POC blood cell separation has been modeled using a finite element method. Tag-less separation of blood cells i.e. platelets, red blood cells, and white blood cells was carried out using standing surface acoustic waves (SSAWs) generated by interdigital transducers (IDTs) located at lateral sides of the microfluidic channel. Blood sample intake along with sheath flow was introduced via two symmetrical tilted angle inlets and middle inlet, respectively. Different parameters like wave frequency, wave amplitude, medium flow rate, and microchannel dimensions were analyzed in order to find the best design and optimum condition of blood cell sorting inside the device. Superposition of acoustic radiation force applied by SSAWs accompanied by drag force caused by medium flow drove the blood cells toward different path lines correlated to their size. Red and white blood cells were sorted out through separate locations in the middle outlet and, platelets were sorted out through the side outlets. Each cell then guided to their respected visualization chamber for further image processing analysis. The results of the presented numerical study would be very promising in designing and optimizing the POC blood testing device.

The oral delivery of cancer chemotherapeutic drugs is challenging due to low bioavailability, gastrointestinal side effects, first-pass metabolism and P-glycoprotein efflux pumps. Thus, chemotherapeutic drugs, including Docetaxel, are administered via an intravenous route, which poses many disadvantages of its own. Recent advances in pharmaceutical research have focused on designing new and efficient drug delivery systems for site-specific targeting, thus leading to improved bioavailability and pharmacokinetics. A decent number of studies have been reported for the safe and effective oral delivery of Docetaxel. These nanocarriers, including liposomes, polymeric nanoparticles, metallic nanoparticles, hybrid nanoparticles, dendrimers and so on, have shown promising results in research papers and clinical trials. The present article comprehensively reviews the research efforts made so far in designing various advancements in the oral delivery of Docetaxel. Different strategies to improve oral bioavailability, prevent first-pass metabolism and inhibition of efflux pumping leading to improved pharmacokinetics and anticancer activity are discussed. The final portion of this review article presents key issues such as safety of nanomaterials, regulatory approval and future trends in nanomedicine research.

Graphene, the mother of all carbon materials, has unlocked a new era of biomedical nanomaterials due to its exceptional biocompatibility, physicochemical and mechanical properties. It is a single atom thick, nanosized, two-dimensional structure and provides high surface area with adjustable surface chemistry to form hybrids. The present article provides a comprehensive review of ever-expanding application of graphene nanomaterials with different inorganic and organic materials in drug delivery and theranostics. Methods of preparation of nanomaterials are elaborated and biological and physicochemical characteristics of biomedical relevance are also discussed. Graphene form nanomaterials with metallic nanoparticles offer multiscale application. First, graphene act as a platform to attach nanoparticles and provide excellent mechanical strength. Second, graphene improves efficacy of metallic nanoparticles in diagnostic, biosensing, therapeutic and drug delivery application. Graphene-based polymeric nanocomposites find wider application in drug delivery with flexibility to incorporate hydrophilic, hydrophobic, sensitive and macromolecules. In addition, grapheme quantum dots and graphene hybrids with inorganic nanocrystal and carbon nanotubes hybrids have shown interesting properties for diagnosis and therapy. Finally, we have pointed out research trends that may be more common in future for graphene-based nanomaterials.

Proniosomes (PN) are the dry water-soluble carrier systems that may enhance the oral bioavailability, stability, and topical permeability of therapeutic agents. The low solubility and low oral bioavailability due to extensive first pass metabolism make Pentazocine as an ideal candidate for oral and topical sustained release delivery. The present study was aimed to formulate the PNs by quick slurry method that are converted to niosomes (liquid dispersion) by hydration, and subsequently formulated to semisolid niosomal gel. The PNs were found in spherical shape in the SEM and stable in the physicochemical and thermal analysis (FTIR, TGA, and XRD). The quick slurry method produced high recovery (> 80% yield) and better flow properties (θ = 28.1–37.4°). After hydration, the niosomes exhibited desirable entrapment efficiency (44.45–76.23%), size (4.98–21.3 μm), and zeta potential (− 9.81 to − 21.53 mV). The in vitro drug release (T100%) was extended to more than three half-lives (2–4 h) and showed good fit to Fickian diffusion indicated by Korsmeyer-Peppas model (n = 0.136–0.365 and R2 = 0.9747–0.9954). The permeation of niosomal gel was significantly enhanced across rabbit skin compared to the pure drug-derived gel. Therefore, the PNs are found promising candidates for oral as dissolution enhancement and sustained release for oral and topical delivery of pentazocine for the management of cancer pain.

Rheumatoid arthritis (RA) is a chronic inflammatory disease of joints with no permanent cure. Although, there are some treatment strategies for RA that can go into remission but a precise treatment strategy is not currently available due to different patient manifestations. In addition, the use of various naturally available anti-inflammatory agents and antioxidants are hampered due to their instability in blood and lack of effective penetration into the synovial fluid. In this study, we aimed to enhance the therapeutic potential of natural but less bioavailable flavonoids by using lipid-based nanocarriers. Three types of lipid nanocarriers including stearic acid (SA), stearic-lauric (SL), and lecithin-chitosan (LC) nanocarriers (with encapsulated naringenin) were prepared by hot melt encapsulation and coprecipitation techniques, respectively. Arthritis in rats was induced by a single injection of complete Freund's adjuvant (CFA) in the sub-planter region of the left hind paw. Thirty six (36) male albino rats were divided into six groups with six animals each. Sole naringenin (NAR) and NAR-loaded lipid NPs (40 mg/kg) were administered orally to treatment groups after 1 h of CFA injection for 28 days continuously. NAR-loaded nanocarriers of spherical shape were synthesized with an average size less than ∼190 nm and zeta potential ( +30 mV for LC). We observed the encapsulation efficiency (EE) of 85%, 78% and 81% for LC, SA and SL, respectively. In vitro release of NAR from all nanoformulations showed sustained release behaviour. NAR loaded all lipid nanoformulations significantly (p

Lipid-polymer hybrid nanoparticles (LPHNPs) are emerging platforms for drug delivery applications. In the present study, methotrexate loaded LPHNPs consisted of PLGA and Lipoid S100 were fabricated by employing a single-step modified nanoprecipitation method combined with self-assembly. A three factor, three level Box Behnken design using Design-Expert® software was employed to access the influence of three independent variables on the particle size, drug entrapment and percent drug release. The optimized formulation was selected through numeric optimization approach. The results were supported with the ANOVA analysis, regression equations and response surface plots. Transmission electron microscope images indicated the nanosized and spherical shape of the LPHNPs with fair size distribution. The nanoparticles ranged from 176 to 308nm, which increased with increased polymer concentration. The increase in polymer and lipid concentration also increased the drug entrapment efficiency. The in vitro drug release was in range 70.34-91.95% and the release mechanism follow the Higuchi model (R2=0.9888) and Fickian diffusion (n

In several pharmacologic, pharmacology, and alternative medicine studies, oral administration of medication or test substances to experimental animals is needed. It is clinically sound and recommended to administer test substances to experimental animals along the same route that they are taken or expected to be taken by humans as general bioavailability; the pharmacology and pharmacology parameters obtained for the drug will depend significantly on the route chosen to administer it. The lack of ready access to high-quality oral tubing built for different species, as well as a widespread lack of technical expertise to properly use out-of-the-box techniques in this part of the world, has made this route controversial among medicine scientists. The typical problems and difficulties associated with the oral administration of test product solutions were avoided by mistreating either the syringe alone or incorporating it into the animals feeds or drinkables. This jury-rigged oral tubing was also used to ensure that the expected doses were correctly administered in each case.

Pharmacokinetic modeling helps to estimate the ADME parameters of all the natural and synthetic drug substances in humans and animals. There are two types of approaches for predicting the kinetic processes inside the body i.e., model approach and model independent approach. Model approach is further divided into compartmental and physiological models and model independent approach consists of non-compartmental models. Compartmental modeling is the most widely used approach. It visually shows the rate processes of drug deposition and also predict the drug concentration time graph. Compartmental model consists of catenary and mammillary models. Mammillary models can either be one compartment, multi compartment or two compartments. The physiologically based pharmacokinetic models consists of compartments that correlates with various body tissues, connected by blood circulatory system. Another name for non- compartmental analysis is model-independent approach that means it does not require any compartment model.

Mathematical model a numerical classification of the biological framework and utilized to state quantitative connections. A pharmacokinetic compartment is a numerical idea that portrays a space in the body that medication seems to possess These models just mediate the test information and permit an experimental equation for the assessment of medication focus with time. A non- compartmental model is a pharmacokinetic model that does not involve the consequence of a definite compartment model is called a Non-compartment model. This approach is based on the consequence that the drugs or substances created in a metabolic process follow direct kinetics, which is the basis that this approach can be functional to any compartment model. The non- compartmental analysis gives an elective strategy to portraying drug pharmacokinetics without appointing a specific compartmental model to the medication.

The rapid change in the failure of antimicrobial therapy due to an increase in the number of infections caused by antimicrobial resistance and the commencement of comprehensive resistant strains robustly claim detection of appliances causing the improvement of drug resistance. In this article, we review the double tactics to decrease antimicrobial resistance infections in hospitals by the improvement of hospital infection prevention and control (IPC) and Antimicrobial Stewardship (AMS) programs and their gradually significant part in decreasing the feast of antibiotic resistance using an ethical framework that enables clinicians and to appraise policies for rational use of an antibiotic in six practical steps. Though the procedure of bacteriophages and antibodies has been partially applied, further encouraging plans, such as probiotics and antimicrobial peptides, are under improvement. Novel approaches such as genetically modified phages and CRISPRCas9 also converse, and plasmid curing and anti-plasmid methods might reduce ARG existence and alert bacteria about antibiotics.

With time viral infections are increasing day by day due to various reasons like new viruses, the resistance of viruses to antiviral therapy, and mutation of one form of the virus to another form; these types of problems create many challenges in the field of research. Furthermore, a lot of challenges are encountered in the treatment of antiviral therapy, like interaction with other medication and use of increased frequency and a high dose of antiviral due to infection in CNS or synovial fluid where drug permeation is less. Consequently, toxicity and other side effect chances will be more. Nano-technological approaches are used to overcome these challenges. The beneficial properties come from such engineering, including stimuli sensitivity, targetability, and longevity; these are all combined to give multifunctional nano-carriers that concurrently execute different beneficial tasks

Complete coverage of all possible test instances in the testing of integrated systems could achieve by using combinatorial testing (CT) strategies. Combinatorial testing has widely been studied in Web service testing research. Few studies related to testing basic web services while others focus on the composite service behavior of web services to generate minimum test cases or test data. This paper is a part of another larger paper that systematically map the available research work on combinatorial testing of web services. The paper presents a Classification scheme to structure the area and to report results based on the answers of three selected research questions. A classification scheme comprises combinatorial techniques algorithms and tools for testing and standard based SUT. This study exposes that even web service testing is getting noteworthy attention still very few approaches of CT applied to test web services.
