A new durable antibacterial cotton fabric was successfully prepared by free-radical graft copolymerization of acrylic acid (AA) and itaconic acid (IA) onto a cotton fabric in an aqueous medium. Ammonium persulfate (APS) was used as the initiator in the presence of a crosslinker, methylene bisacrylamide (MBA). The nanocomposite hydrogel was obtained from in situ formation of silver nanoparticles from reduction of silver cations by sodium borohydride. A proposed mechanism for nanocomposite formation was suggested and the effect of ratio of IA to AA on water absorbency discussed. FTIR, UV-Vis, X-ray, and scanning electron microscopy were employed to characterize the structure of the prepared superabsorbent. The antibacterial activity of the hydrogel was tested qualitatively and quantitatively. Results showed that the silver nanoparticle-loaded fabric has potent antibacterial activity to Escherichia coli Gramnegative bacteria.

Background:The preparation of silver nanoparticles often involves some tedious steps and extra reducing agents. PDMAEMA and β-CD can act as the reducing and stabilizing agents for the preparation of silver nanoparticles without any external reducing agent. Methods: β-Cyclodextrin-g-Poly (2-(dimethylamino) ethylmethacrylate) as the stabilizer and reductant to prepare colloid silver nanoparticles in situ. Such an approach greatly simplified the preparation and purification of silver nanoparticles. Results: The graft yield of β-CD-g-PDMAEMA increased with the increase of amount of DMAEMA.Ag nanoparticles was obtained under neutral or slightly alkaline environment.The intensity of surface plasmon resonance peak of Ag nanoparticles increased as the concentration of β-CD-g-PDMAEM and silver nitrate increased. In addition, the Ag nanoparticles were in the form of spherical particles observed by transmission electron microscopy (TEM). The FTIR spectrum of nanocomposite showed that coordination existed between the silver nanoparticles and tertiary amino groups of PDMAEMA segments. Conclusion: Silver nanoparticles were successfully prepared by in situ synthetic method, using β-CD-g-PDMAEMA as both reductant and stabilizer. It can be envisioned that the theroresponsive silver nanocomposite could find applications in biomedical feld.

“…39,41,43,61,62,[87][88][89][90][91] By combining several materials, different groups have developed antibacterial coatings that are anticorrosive, 39,43 titanium dioxide has also been combined with both silver nanoparticles and zinc oxide (ZnO) to improve the broad-spectrum antibacterial coverage of the coating. 61,62 Selvam et al demonstrated that the ZnO in these coatings performed better against both S. aureus and E. coli than the TiO 2 and silver nanoparticles alone. 61 It is hypothesized that the ZnO enhances the antibacterial activity because it readily permeates bacterial membranes through the generation of hydrogen peroxide.…”

This work provides an overview, with advantages and limitations of the most recently developed antibacterial coating technologies, enabling other researchers in the field to more easily determine which technology is most advantageous for them to further develop and pursue. AbstractOver the past 20 years, the field of antimicrobial medical device coatings has expanded nearly 30-fold with technologies shifting their focus from diffusion-only based (short-term antimicrobial eluting) coatings to long-term antimicrobial eluting and intrinsically antimicrobial functioning materials. A variety of emergent coatings have been developed with the goal of achieving long-term antimicrobial activity in order to mitigate the risk of implanted device failure. Specifically, the coatings can be grouped into two categories: those that use antibiotics in conjunction with a polymer coating and those that rely on the intrinsic properties of the material to kill or repel bacteria that come into contact with the surface. This review covers both long-term drug-eluting and non-eluting coatings and evaluates the inherent advantages and disadvantages of each type while providing an overview of variety applications that the coatings have been utilized in.
