Abstract

This work explores the use of ZIF-8, a metal–organic framework (MOF) material, for its use in the optical detection of volatile organic compounds (VOCs) in Fabry–Pérot and surface plasmon resonance (SPR)-based sensors. The experiments have been carried out with ethanol (EtOH) and show response times as low as 30 s under VOC-saturated atmospheres, and the estimated limit of detection is below 4000 ppm for both sensor types. The selectivity towards other VOCs is relatively poor, although the dynamics of adsorption/desorption differ for each VOC and could be used for selectivity purposes. Furthermore, the hydrophobicity of ZIF-8 has been confirmed and the fabricated sensors are insensitive to this compound, which is a very attractive result for its practical use in gas sensing devices.

Abstract

Digital microfluidics (DM) is an advanced technology in microfluidics where electrowetting force is used to control and manipulate nanolitre and microliter-sized droplets on a set of electrodes.1 DM has gained considerable attention because of fast heat transfer, less reagent volume due to miniaturization of reaction, small footprints and incredible control of droplets. This technique minimizes the analysis time and efforts and offers innovative prospects for process automation and integration in a unique setup. It is very favorable for high throughput applications. The movement of droplets using DM requires a hydrophobic surface on which the processes can be performed easily. SLIPS (Slippery liquid infused porous surface) have been demonstrated to be used as a surface for digital microfluidics because of antifouling properties and fine movement of droplets.2 SLIPS is fabricated by utilizing porous polymeric substrate infused with the slippery fluid. PCR product purification is important step in molecular cloning. The purification is done to remove the enzymes, primers, salts and other non-reacted components from the reaction to get pure amplified band.3 The purity of PCR product is crucial for the gene sequencing, aptamer sequencing and cloning. In addition to this, whole genome sequencing techniques have increased the need for the purity of the nucleic acids used. Purification of DNA using commercially available kits is cumbersome, time-consuming and generates a lot of plastic waste. With digital microfluidics, the high throughput purification of nucleic acids can be achieved. The DM platform used in this study is developed in-house.4 Magnetic nanoparticles have been employed for the purification of PCR product on the DM platform as they have tendency to bind to the DNA. The binding of the DNA to the nanoparticles can be tuned by altering the ratio of DNA and nanoparticles. A pure DNA band, free of primers is obtained on agarose gel after purification via

Abstract

Although aquaculture is a major player in current and future food production, the routine use of antibiotics provides ample ground for development of antibiotic resistance. An alternative route to disease control is the use of probiotic bacteria such as the marine bacteria Phaeobacter inhibens which produces tropodithietic acid (TDA) that inhibit pathogens without affecting the fish. Improving conditions for the formation of biofilm and TDA-synthesis is a promising avenue for biocontrol in aquaculture. In this study, the biosynthesis of TDA by Phaeobacter inhibens grown on micro-structured polymeric surfaces in micro-fluidic flow-cells is investigated. The formation of biofilms on three surface topographies; hexagonal micro-pit-arrays, hexagonal micro-pillar-arrays, and planar references is investigated. The biomass on these surfaces is measured by a non-invasive confocal microscopy 3D imaging technique, and the corresponding TDA production is monitored by liquid chromatography mass spectrometry (LC-MS) in samples collected from the outlets of the microfluidic channels. Although all surfaces support growth of P. inhibens, biomass appears to be decoupled from total TDA biosynthesis as the micro-pit-arrays generate the largest biomass while the micro-pillar-arrays produce significantly higher amounts of TDA. The findings highlight the potential for optimized micro-structured surfaces to maintain biofilms of probiotic bacteria for sustainable aquacultures.

13. Using Impedance Flow Cytometry for Rapid Viability Classification of Heat-Treated Bacteria

Author

Bertelsen, Christian Vinther, Skands, Gustav Erik, González Díaz, Marcos, Dimaki, Maria, Svendsen, Winnie Edith, Bertelsen, Christian Vinther, Skands, Gustav Erik, González Díaz, Marcos, Dimaki, Maria, and Svendsen, Winnie Edith

Abstract

In the future, rapid electrical characterization of cells with impedance flow cytometry promises to be a fast and accurate method for the evaluation of cell properties. In this paper, we investigate how the conductivity of the suspending medium along with the heat exposure time affects the viability classification of heat-treated E. coli. Using a theoretical model, we show that perforation of the bacteria membrane during heat exposure changes the impedance of the bacterial cell from effectively less conducting than the suspension medium to effectively more conducting. Consequently, this results in a shift in the differential argument of the complex electrical current that can be measured with impedance flow cytometry. We observe this shift experimentally through measurements on E. coli samples with varying medium conductivity and heat exposure times. We show that increased exposure time and lower medium conductivity results in improved classification between untreated and heat-treated bacteria. The best classification was achieved with a medium conductivity of 0.045 S/m after 30 min of heat exposure.

14. Diphenylalanine Peptide Nanowires as a Substrate for Neural Cultures

Author

Walls, Anne B., Dimaki, Maria, Korsgaard, Tanya, Swiniarska, Małgorzata M., Castillo-León, Jaime, Waagepetersen, Helle S., and Svendsen, Winnie E.

Abstract

Primary brain cells cultured on flat surfaces, i.e., in a two-dimensional fashion, have a long history of use as an experimental model system in neuroscience research. However, it is questionable to which extent these cultured brain cells resemble their in vivo counterparts. Mainly, it has been claimed that the non-oxidative glucose metabolism reflected by lactate production is unphysiologically high. Furthermore, it is known that culturing in 2D alters the phenotype of cells. Here we present diphenylalanine peptide nanowires (PNWs) as a culturing substrate for primary neocortical neurons from mice. The topology of the PNWs leads to neuronal cultures developing in 2.5D environment and hence improved culturing conditions. We investigate the effect of different concentrations of PNWs and different cell densities of neurons on the culturing conditions. The neocortical neurons were examined through scanning electron microscopy in order to study the effect of PNW concentrations and neuron densities on the structural appearance of the cells. Then employing the optimal combination of neuron density and PNW concentration, the neurons were evaluated functionally and metabolically by comparison with neocortical neurons standard culturing methods in 2D. Specifically, we tested neuronal viability, capacity for vesicular release of neurotransmitter GABA, as well as oxidative and non-oxidative glucose metabolism. It was evident that neurons cultured on PNWs exhibited increased viability combined with an increased capacity for neurotransmitter release and a lower fraction of non-oxidative metabolism than neurons cultured in 2D. Hence, neocortical neurons cultured in 2.5D on PNWs appear to be healthier and less glycolytic than neurons cultured in 2D.

29. Sub-100 nm Nanoparticle Upconcentration in Flow by Dielectrophoretic Forces

Author

Dimaki, Maria, Olsen, Mark Holm, Rozlosnik, Noemi, Svendsen, Winnie E., Dimaki, Maria, Olsen, Mark Holm, Rozlosnik, Noemi, and Svendsen, Winnie E.

Abstract

This paper presents a novel microfluidic chip for upconcentration of sub-100 nm nanoparticles in a flow using electrical forces generated by a DC or AC field. Two electrode designs were optimized using COMSOL Multiphysics and tested using particles with sizes as low as 47 nm. We show how inclined electrodes with a zig-zag three-tooth configuration in a channel of 20 µm width are the ones generating the highest gradient and therefore the largest force. The design, based on AC dielectrophoresis, was shown to upconcentrate sub-100 nm particles by a factor of 11 using a flow rate of 2-25 µL/h. We present theoretical and experimental results and discuss how the chip design can easily be massively parallelized in order to increase throughput by a factor of at least 1250.

Abstract

The North American terrapin, the red-eared slider, has globally recognized invasive status. We built a new extensive database using our own original and literature data on the ecology of this reptile, representing information on 1477 water bodies throughout Eurasia over the last 50 years. The analysis reveals regions of earliest introductions and long-term spatio-temporal dynamics of the expansion covering now 68 Eurasian countries, including eight countries reported here for the first time. We established also long-term trends in terms of numbers of terrapins per aquatic site, habitat occupation, and reproduction success. Our investigation has revealed differences in the ecology of the red-eared slider in different parts of Eurasia. The most prominent expression of diverse signs of invasion success (higher portion of inhabited natural water bodies, higher number of individuals per water body, successful overwintering, occurrence of juvenile individuals, successful reproduction, and establishment of populations) are typical for Europe, West Asia and East Asia and tend to be restricted to coastal regions and islands. Reproduction records coincide well with the predicted potential range based on climatic requirements but records of successful wintering have a wider distribution. This invader provides an excellent and possibly unique (among animals) example of wide alien distribution, without the establishment of reproducing populations, but through the recruitment of new individuals to rising pseudopopulations due to additional releases. Therefore, alongside the potential reproduction range, a cost-effective strategy for population control must take in account the geographical area of successful wintering. [ABSTRACT FROM AUTHOR]

Abstract

Lamellar and non‐lamellar liquid crystalline nanodispersions, including liposomes, cubo-somes, and hexosomes are attractive platforms for drug delivery, bio‐imaging, and related pharmaceutical applications. As compared to liposomes, there is a modest number of reports on the continuous production of cubosomes and hexosomes. Using a binary lipid mixture of citrem and soy phosphatidylcholine (SPC), we describe the continuous production of nanocarriers for delivering thymoquinone (TQ, a substance with various therapeutic potentials) by employing a commercial microfluidic hydrodynamic flow‐focusing chip. In this study, nanoparticle tracking analysis (NTA) and synchrotron small‐angle X‐ray scattering (SAXS) were employed to characterize TQ‐free and TQ‐loaded citrem/SPC nanodispersions. Microfluidic synthesis led to formation of TQ‐free and TQ-loaded nanoparticles with mean sizes around 115 and 124 nm, and NTA findings indicated comparable nanoparticle size distributions in these nanodispersions. Despite the attractiveness of the mi-crofluidic chip for continuous production of citrem/SPC nano‐self‐assemblies, it was not efficient as comparable mean nanoparticle sizes were obtained on employing a batch (discontinuous) method based on low‐energy emulsification method. SAXS results indicated the formation of a biphasic feature of swollen lamellar (Lα) phase in coexistence with an inverse bicontinuous cubic Pn3m phase in all continuously produced TQ‐free and TQ‐loaded nanodispersions. Further, a set of SAXS experiments were conducted on samples prepared using the batch method for gaining further insight into the effects of ethanol and TQ concentration on the structural features of citrem/SPC nano‐self-assemblies. We discuss these effects and comment on the need to introduce efficient microfluidic platforms for producing nanocarriers for delivering TQ and other therapeutic agents.

Abstract

Bacteria detection, counting and analysis is of great importance in several fields. When viability plays a major role in decision making, the counting of colony-forming units grown on agar plates remains the gold standard. However, because plate counts depend on the growth of the bacteria, it is a slow procedure and only works with culturable species. Impedance flow cytometry (IFC) is a promising technology for particle detection, counting and characterization. It relies on the perturbation of an electric field by particles flowing through a microfluidic channel. The perturbation is directly related to the electrical properties of the particles, and therefore provides information about their composition and structure. In this work we investigate whether IFC can be used to differentiate viable cells from inactivated cells. Our findings demonstrate that the specific viability state of the bacteria has to be considered, but that with proper characterization thresholds, IFC can be used to classify bacterial viability states. By using three different inactivation methods-ethanol, heat and autoclavation-we have been able to show that the impedance response of Escherichia coli depends on its viability state, but that the specific response depends on the inactivation method. With these findings we expect to be able to optimize IFC for more reliable bacteria detection and counting in the future.

Abstract

Pyocyanin is a virulence factor solely produced by the pathogen Pseudomonas aeruginosa. Pyocyanin is also a redox active molecule that can be directly detected by electrochemical sensing. A nanograss (NG) based sensor for sensitive quantification of pyocyanin in sputum samples from cystic fibrosis (CF) patients is presented here. The NG sensors were custom made in a cleanroom environment by etching nanograss topography on the electrode surface followed by depositing 200 nm gold. The NG sensors were utilized for amperometric quantification of pyocyanin in spiked hypertonic saline samples, resulting in a linear calibration curve with a R2 value of 0.9901 and a limit of detection of 172 nM. The NG sensors were applied in a small pilot test on five airway samples from five CF patients. The NG sensor was capable of identifying P. aeruginosa in the airway samples in 60 s without any sample pretreatment.

Abstract

Monitoring and control of manufacturing processes is of great importance in all industries. Bioprocesses use living microorganisms to produce a broad range of valuable goods such as proteins, hormones, enzymes or fermented food products. In a bioprocess, metabolite concentrations vary with the different fermentation phases. Non-ideal mixing conditions further contribute to the formation of local concentration gradients. These conditions render process monitoring a challenging task, specifically in large bioreactors. To ensure high product yields, product quality and process consistency, it is essential to monitor and control the bioreactor, which is tightly connected with the metabolism of the microorganisms. Therefore, being able to measure physico-chemical processes from a quantitative and qualitative perspective is key to achieving successful process control [1]. At many production sites nowadays, simple real-time monitoring systems are already implemented. These systems rely on measurements providing a limited number of variables such as pH, temperature, dissolved oxygen concentration, and carbon dioxide evolution rate (CER). Contrary to that, information concerning biologically important variables such as the concentration of different nutrients, metabolites, and biomass is mainly available by laborious off-line analyses [2]. Over the past decades, there has been an increasing focus on process analytical techniques (PAT) that allow rapid and non-destructive measurements in the frame of fermentation based manufacturing. Therefore, the sensing techniques employed need to be rapid to facilitate this deeper understanding of the process. Rapid quantification is also required for improved process control. On-line monitoring of key primary and secondary metabolites enables fast decision-making through applying dynamic feeding strategies that are tailored to the process conditions. Electrochemical (bio)sensors offer the possibility of on-line monitoring in combination
