Pathogenic bacteria consistently pose significant challenges within the oral mucosal environment by altering bioflora, biofilm development, and enamel demineralization, thus leading to extensive clinical resources for treatment. This review aims to gather suitable and novel information in terms of providing advanced bio-inspired therapeutic facilities to alleviate the burden of treatment on both the patient and medical infrastructure. Botanical nanoparticle-based mouthwashes have been synthesized using mostly green synthesis technology. Botanical nanoformulations-based mouthwashes are efficient for maintaining microbial flora and mimicking natural extracellular matrix (ECM) components. Furthermore, dental caries can also be treated by these nanoparticles through the promotion of enamel remineralization and bacterial growth suppression. These nature-inspired oral rinses/mouthwashes confer significant advantages relative to their synthetic counterparts, particularly in terms of safety, efficacy, and formulation simplicity. The potential applications of these bioinspired nanomaterials extend beyond wound healing and dental infection management, heralding a promising frontier in oral health restoration. The diversified range of these nanomaterials, from Propolis, Miswak, and Chitosan nanoparticles (NPs) to pomegranate extract and Matricaria chamomilla L. extract-based mouthwashes, introduces an exciting new dimension to oral care.

The inculcation of bioinspiration in sensing and human-machine interface (HMI) technologies can lead to distinctive characteristics such as conformability, low power consumption, high sensitivity, and unique properties like self-healing, self-cleaning, and adaptability.

[Display omitted] • Crb-PβAE-ALG NPs were prepared by ionic gelation. • The NPs were subsequently coated by platelet membrane (PltM) using ultra-sonication method. • Bioinspired Crb-loaded platelets (Plt@Crb) were also prepared for comparison. • Plt@Crb and PltM@Crb-PβAE-ALG NPs exhibited enhanced cytotoxicity in 4 T1 cells. • PltM@Crb-PβAE-ALG NPs demonstrated superior therapeutic efficacy than Plt@Crb in vivo. Triple-negative breast cancer (TNBC) has poor prognosis. Carboplatin (Crb) is a widely used chemotherapeutic agent, in TNBC but with serious systemic toxicity and poor tumor targeting. Bioinspired drug-loaded platelets (Plt) and Plt-coated nanocarriers evade macrophage phagocytosis by membrane proteins like CD47. The goal of this study was preparation of a novel alginate-poly (β-amino ester) (PβAE) nanoparticles (NPs) for targeted delivery of Crb to TNBC cells by developing and comparison of two bioinspired carriers of Plt membrane (PltM) coated Crb-loaded alginate-poly (β-amino ester) nanoparticles (PltM@Crb-PβAE-ALG NPs) and Plt loaded Crb (Plt@Crb). The NPs were prepared by ionic gelation and subsequently were coated by platelet membrane using ultra-sonication method. The loading efficiency, release profile, and in vitro cytotoxicity of both formulations were evaluated on HUVEC and 4 T1 cells. Additionally, the in vivo tumor targeting, therapeutic efficacy, and organ toxicity of the two formulations were assessed in a murine tumor model. Results showed both Plt@Crb and (PltM@Crb-PβAE-ALG NPs) exhibited high drug loading efficiency, sustained release, enhanced cytotoxicity against 4 T1 cells, and decreased cytotoxicity in normal cells (HUVEC) in vitro. In vivo studies revealed that although both formulations considerably improved tumor inhibition compared to free Crb, but the PltM@Crb-PβAE-ALG NPs demonstrated superior cytotoxicity and therapeutic efficacy, thanks to improved Crb's internalization efficiency, enhanced stability, and controlled release properties.

Polyserotonin nanoparticles (PSeNP) and films are bioinspired nanomaterials that have potential in biomedical applications and surface coatings. As studies on polyserotonin (PSe) nanoparticles and films are still in their infancy, synthetic pathways and material development for this new class of nanomaterial await investigation. Here, we sought to determine how different buffers used during the polymerization of serotonin to form nanoparticles and films impact the physicochemical properties of PSe materials. We show that buffer components are incorporated into the polymer matrix, which is also supported by density functional theory calculations. While we observed no significant differences between the elasticity of nanoparticles synthesized in the different buffers, the nanoscale surface properties of PSe films revealed dissimilarities in surface functional groups influenced by solvent molecules. Overall, the results obtained in this work can be used towards the rational design of PSe nanomaterials with tailored properties and for specific applications. [ABSTRACT FROM AUTHOR]

Staphylococcus haemolyticus is a cause of bovine mastitis, leading to inflammation in the mammary gland. This bacterial infection adversely affects animal health, reducing milk quality and yield. Its emergence has been widely reported, representing a significant economic loss for dairy farms. Interestingly, S. haemolyticus exhibits higher levels of antimicrobial resistance than other coagulase-negative Staphylococci. In this study, we synthesized silver/silver chloride nanoparticles (Ag/AgCl-NPs) using Solanum lasiocarpum root extract and evaluated their antibacterial and antibiofilm activities against S. haemolyticus. The formation of the Ag/AgCl-NPs was confirmed using UV–visible spectroscopy, which revealed maximum absorption at 419 nm. X-ray diffraction (XRD) analysis demonstrated the crystalline nature of the Ag/AgCl-NPs, exhibiting a face-centered cubic lattice. Fourier transform infrared (FT-IR) spectroscopy elucidated the functional groups potentially involved in the Ag/AgCl-NPs synthesis. Transmission electron microscopy (TEM) analysis revealed that the average particle size of the Ag/AgCl-NPs was 10 nm. Antimicrobial activity results indicated that the minimum inhibitory concentration (MIC) and maximum bactericidal concentration (MBC) of the Ag/AgCl-NPs treatment were 7.82–15.63 μg/mL towards S. haemolyticus. Morphological changes in bacterial cells treated with the Ag/AgCl-NPs were observed under scanning electron microscopy (SEM). The Ag/AgCl-NPs reduced both the biomass of biofilm formation and preformed biofilm by approximately 20.24–94.66 % and 13.67–88.48 %. Bacterial viability within biofilm formation and preformed biofilm was reduced by approximately 21.56–77.54 % and 18.9–71.48 %, respectively. This study provides evidence of the potential of the synthesized Ag/AgCl-NPs as an antibacterial and antibiofilm agent against S. haemolyticus. • Ag/AgCl-NPs were synthesized using S. lasiocarpum root extract. • Ag/AgCl-NPs showed potent antibacterial and antibiofilm activity. • Ag/AgCl-NPs reduced biofilm biomass and bacterial cell viability.

The industry transfer of laboratory-use magnetic separation is still hampered by the lack of suitable nanoparticles, both in terms of their features and large-scale availability. Surface Active Maghemite Nanoparticles (SAMNs) characterized by a unique surface chemistry, low environmental impact, scalable synthesis and functionalization were used to develop a bio-inspired lactoferrin (LF) recognition system. Based on the LF affinity for DNA, a self-assembly process was optimized for obtaining a SAMN@DNA hybrid displaying chemical and colloidal stability and LF specificity. SAMN@DNA was successfully tested for the affinity purification of LF from crude bovine whey. Advantages, such as high selectivity and loading capacity, nanoparticle re-usability, outstanding purity (96 ± 1%), preservation of protein conformation and short operational time, were highlighted. Finally, scalability was demonstrated by an automatic system performing continuous purification of LF from 100 liters day−1 of whey. This study responds to essential prerequisites, such as efficiency, re-usability and industrialization feasibility. [Display omitted] • A nano-hybrid recognition site is revealed by molecular modelling on lactoferrin surface. • ɣ-Fe2O3-DNA-lactoferrin hybrid is prepared by self-assembly and characterized. • ɣ-Fe2O3-DNA nanomaterial is optimized for lactoferrin affinity purification. • High-purity and high-yield lactoferrin is attained in two hours by magnetic isolation. • An automatic pilot-plant purifying 100 L day-1 lactoferrin from whey is presented.

• We compare the efficacy of bioinspired nanomaterials with that of existing conventional dressings. • We discuss the anti-microbial and anti-biofilms activities of bioinspired nanomaterials in promoting wound healing. • We review approaches used to target bioinspired nanomaterials for delivery at wound sites. Chronic wounds are ubiquitously inhabited by bacteria, and they remain a challenge as they cause significant discomfort and because their treatment consumes huge clinical resources. To reduce the burden that chronic wounds place upon both patients and health services, a wide variety of approaches have been devised and investigated. Bioinspired nanomaterials have shown great success in wound healing when compared to existing approaches, showing better ability to mimic natural extracellular matrix (ECM) components and thus to promote cell adhesion, proliferation, and differentiation. Wound dressings that are based on bioinspired nanomaterials can be engineered to promote anti-inflammatory mechanisms and to inhibit the formation of microbial biofilms. We consider the extensive potential of bioinspired nanomaterials in wound healing, revealing a scope beyond that covered previously. [ABSTRACT FROM AUTHOR]

Abstract: Microorganisms naturally form biofilms on solid surfaces for their mutual benefits including protection from environmental stresses caused by contaminants, nutritional depletion or imbalances. The biofilms are normally dangerous to human health due to their inherited robustness. On the other hand, a recent study suggested that electrochemically active biofilms (EABs) generated by electrically active microorganisms have properties that can be used to catalyze or control the electrochemical reactions in a range of fields, such as bioenergy production, bioremediation, chemical/biological synthesis, bio-corrosion mitigation and biosensor development. EABs have attracted considerable attraction in bioelectrochemical systems (BESs), such as microbial fuel cells and microbial electrolysis cells, where they act as living bioanode or biocathode catalysts. Recently, it was reported that EABs can be used to synthesize metal nanoparticles and metal nanocomposites. The EAB-mediated synthesis of metal and metal–semiconductor nanocomposites is expected to provide a new avenue for the greener synthesis of nanomaterials with high efficiency and speed than other synthetic methods. This review covers the general introduction of EABs, as well as the applications of EABs in BESs, and the production of bio-hydrogen, high value chemicals and bio-inspired nanomaterials.
