“…12 Bigger and more protuberances would be among the nanofibrous membranes because of the high positive charge of the composites. 20 In contrast, the negative charge of REC neutralized the positive charge of LY, which contributed to the decrease of beads.…”

“…Various methods applied to immobilize LY include protein adsorption onto nanoparticles, [17][18][19] layer-by-layer assembly technique, 20,21 surface grafting modification 22 and the embedding methods, 23 and so on. Considering the weakness of those methods, such as the craft complicacy, the technical difficulties and the toxicity of raw materials, more efforts have been made to explore new methods of immobilizing LY.…”

Lysozyme (LY) exfoliated rectorite (REC) based electrospun nanofibrous membranes with enhanced bacterial inhibition ability and thermostability were fabricated via electrospinning. All the obtained membranes exhibited better fiber shape and threedimensional structure, which could be observed by scanning electron microscopy. Energy-dispersive X-ray analysis, X-ray photoelectron spectroscopy, and Fourier transform infrared (FTIR) spectrum denoted the existence of LY and REC in the composite membranes. Besides, the FTIR results suggested that there were interactions between REC and polyvinyl alcohol (PVA)/LY chains. Small angle X-ray diffraction indicated that REC was exfoliated by PVA and LY chains. In addition, the exfoliation of REC was directly confirmed by transmission electron microscopy. According to Brunauer-Emmett-Teller surface area test results, PVA/LY/REC membranes had higher surface area than that of PVA/LY membranes. The performance tests showed that both the thermal stability and antibacterial activity of the composite membranes were enhanced after adding REC.

“…Subsequently, the modi¯ed CS was polymeric assembled with a polyanion to achieve better contact killing. For example, negatively charged electrospun cellulose acetate¯brous mats were modi¯ed with multilayers of the positively charged intercalated composites including chitosan-organic rectorite (OREC), 54 lysozyme-chitosan-OREC, 55 and quaternized carboxymethyl-chitosan-OREC 56 and the negatively charged sodium alginate via polymeric assembly approach. The polymeric structured¯brous mats enhanced the inhibition against E. coli and S. aureus.…”

This paper will update readers on the latest work in the area of antibacterial polymeric systems. There is extensive literature on existing systems. This complexity con¯nes us to the latest antibacterial materials which possess (1) responsive antibacterial activity on their own; (2) antibio¯lm formation and (3) formation of antibacterial polymeric¯lms. The objective of this review is to provide an overview of the antibacterial synthetic polymer¯eld. In this paper, I will analyze the early promise of this technology as well as highlight potential challenges that adopters could face. The primary focus will be the application of materials to the medical industry and to show how these materials can be tailored to create responsive, customized bactericidal materials.

“…16,17 Chitosan has several interesting properties including, biodegradability, nontoxicity and fungicidal effects, which make it an attractive material for uses in a wide range of industries. 5,[18][19][20][21][22][23][24][25][26] However, electrospinning of chitosan has proven to be difficult, because of the poor solubility of chitosan in water. Many researchers have investigated the effect of solvents on the morphology of chitosan nanobers, such as, acetic acid, hydrochloric acid, formic acid and triuoroacetic acid (TFA).…”

Needleless electrospinning for scaled-up production of ultrafine chitosan hybrid nanofibers used for air filtration

et al. 2016

Large scale ultrafine chitosan hybrid nanofibers containing TiO 2 and/or Ag nanoparticles were prepared using a needleless electrospinning method. The nanofiber production rate reached 50 g h À1 using the needleless electrospinning method, which was much higher than 0.02-1 g h À1 in the traditional single needle electrospinning method. By optimizing the spinning parameters, nanofibers with a smooth uniform morphology were obtained with diameters ranging from 25 to 60 nm and Ag nanoparticles with an average size of 2.9 nm were deposited on the surface of the nanofibers without aggregation. The hybrid nanofibers exhibited a significant increase in filtration efficiency (>99%) for removal of nanoparticle aerosols, comparable to commercial high-efficiency particulate air filters, but with a lower pressure drop and less mess. The chitosan hybrid nanofibers showed excellent antibacterial activity, e.g.97% of E. coli and 99% of S. aureus were killed within 2 h. The cross-linked nanofibers exhibited excellent water durability and maintained a stable microstructure in high humidity and in water immersion. Daily productivity can be above 1.2 kg, which makes these ultrafine nanofibers suitable for the application of wound dressing, air filtration and environmental purification.
