“…PVA has been widely used for the synthesis of antimicrobial nanofibers because of its inexpensiveness, biocompatibility, biodegradability, and non-toxicity [29,[32][33][34][35][36]. For the synthesis of antimicrobial PVA nanofibers, various antimicrobial agents including metal or metal oxide nanoparticles (Ag, TiO 2 , CuO, ZnO) [25,32,37], phosphonium salts [38], quaternarized chitosan [26,27], antibacterial drug [20,24], carbonaceous nanomaterials [39][40][41], tea extraction [25], and quaternary ammonium compounds (QACs) [28,38,42] have been incorporated into the PVA polymer solution.…”

“…Electrospun fibrous membranes can overcome the limitations exhibited by other types of polymeric and ceramic membranes employed in water remediation processes due to their higher porosities and interconnected pore structures offering higher permeability to water during filtration. [22][23][24][25] Under this perspective, a new approach for water disinfection through a pH-responsive (cationic) electrospun polymer membrane is presented herein. 21 The latter is a very important requirement in processes where water disinfection takes place through bacteria adsorption onto the membrane.…”

“…,24,26,36,37 The antibacterial efficiency requires an antimicrobial agent that could lead to bacterial death. However, membrane modification by adding such chemicals may result to the generation of harmful products.In this study bacteria removal is realized via the development of electrostatic attractive interactions between the (gram-negative) P. aeruginosa and Advenella sp.…”

Electrospun microfibrous membranes comprised of poly(methyl methacrylate)-poly((2diethylaminoethyl) methacrylate) random copolymers (PMMA-co-PDEAEMA) of various chemical compositions blended together with a commercially available PMMA have been fabricated with diameters between 4.0-6.4 µm and further evaluated as adsorbents for bacteria removal from aqueous media. The morphology and thermal stability of the membranes were determined by scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA), respectively. Tensile tests were also performed in order to investigate their mechanical properties. Membrane evaluation as adsorbents against two gram-negative bacteria namely Pseudomonas aeruginosa and Advenella species revealed that the membranes containing the highest percentage of the cationic moieties (DEAEMA) exhibited the highest adsorption efficiency. The bacteria removal by the microfibrous membranes was studied by UV-vis spectrophotometry upon measuring the optical density (OD) of the microorganisms. The highest recorded bacteria removal percentages after 8 hr were approximately 70% and 45%, for the Pseudomonas aeruginosa and Advenella species respectively, whereas in both cases complete (100%) bacteria removal was observed after 24 hr of membrane immersion in bacteria-containing aqueous solutions. The experimental adsorption isotherms for P. aeruginosa and Advenella sp. were well-fitted with the Langmuir isotherm model indicating a monolayer adsorption process. SEM was also used to confirm the adhesion of the bacteria onto the electrospun microfibers. Most importantly, these materials exhibited great performance on the removal of microorganisms from urban wastewater as determined via the standard plating technique prepared by agar. Methyl methacrylate (MMA, Fluka, ≥ 99%), poly(methyl methacrylate) (PMMA) (Mw ∼ 350 000, Sigma-Aldrich), n-hexane (Scharlau, 96%), tetrahydrofuran (THF, Scharlau, extra pure) and ethyl acetate (EA, Scharlau, GC grade, 99.8%) were used without further purification. 2-(diethylaminoethyl) methacrylate (DEAEMA, Sigma-Aldrich, 99%) was passed through a basic alumina column prior to the polymerizations and used without further purification. The radical initiator 2,2'-azobis(2-methylpropionitrile) (AIBN, Sigma-Aldrich, 95%) was recrystallized twice from ethanol. Deuterated chloroform (CDCl 3 , Merck), glutaraldehyde (Sigma-aldrich, 25% in water), calcium chloride dihydrate (CaCl 2 .2H 2 O, Scharlau, Reagent grade), ammonium sulfate ((NH 4 ) 2 SO 4 , Scharlau, reagent grade), sucrose (Himedia), potassium phosphate dibasic (K 2 HPO 4 , Sigma-aldrich, ≥98%), magnesium chloride (MgCl 2 , Sigma, ≥98%) and sodium chloride (NaCl, Himedia) were used as received by the manufacturer. The selected gram-negative microorganisms Pseudomonas aeruginosa LVD-10 and Advenella species LVX-4 were provided by the Applied Microbiology Laboratory culture collection of the Cyprus University of Technology. They were previously isolated and deposited in GenBank with accession number KF728673.1 for P. ...

“…Bubble electrospinning, blown-film methods, and multiple pendant drop jets from porous tubes have been reported to be scalable and able to reach productions as high as 10 g/h. 6,7 In bubble electrospinning, the bubbles create the curved surface analogous to the pendant drop of conventional electrospinning leading to a particularly suitable process for large scale production of nanofibers. Bubble technique involves the formation of multiple electrostatically driven jets of polymer from every charged bubble of polymer solution and, therefore, the system requires higher voltage than that used in conventional needle spinning.…”

“…Apparently the biocidal chemical did not leach into filtered water but was effective inhibiting surface-attachment of bacteria. 7 The natural antibacterial property of chitosan was also claimed for water filtration in chitosan-PCL mats, which showed effective against S. aureus adhesion with high flux, an almost complete removal of 300 nm beads and good membrane integrity. 126 Chemical post-functionalization was used to decorate electrospun PAN with silver, either as Ag C or forming silver nanoparticles.…”

Electrospinning is a versatile technique providing highly tunable nanofibrous nonwovens. Many biomedical applications have been developed for nanofibers, among which the production of antimicrobial mats stands out. The production of scaffolds for tissue engineering, fibers for controlled drug release, or active wound dressings are active fields of research exploiting the possibilities offered by electrospun materials. The fabrication of materials for active food packaging or membranes for environmental applications is also reviewed. We attempted to give an overview of the most recent literature related with applications in which nanofibers get in contact with living cells and develop a nano-bio interface.
