2020) Development of silver nanoparticle-based hydrogel composites for antimicrobial activity, Green Chemistry Letters and Reviews, 13:1, 34-40, ABSTRACT Antimicrobial function of Ag nanoparticles (NPs) has a strong correlation with the released Ag + cations that are produced by oxidation of Ag NPs in a solution state under ambient condition. Therefore, in order to develop anti-infective materials for biomedical applications, one needs to include Ag NPs inside biocompatible materials, which can allow slow release of Ag + cations. Hydrogels of natural polymers could be an ideal choice for the purpose because (a) the physicochemical properties of hydrogels resemble with biological tissue, and (b) the inclusion of Ag NPs inside hydrogels prevents the direct release of Ag NPs, while allowing the release of Ag + cations out of the hydrogels. In this regard, we present a simple strategy for producing Ag NPscontaining hydrogel based on natural alginate polymers. The chemical modification of alginate, blending with Ag NPs, gelation by photo-crosslinking process have been discussed in connection with antimicrobial reaction on model bacterium.

Polydopamine was utilized an adhesive interface for the uniform coating of Au nanoparticles in the pores of polydimethylsiloxane to enhance the output performance of triboelectric nanogenerators.

Engineering plasmonic nanoparticles (NPs) into superstructures comprising two or more distinctive materials is highly desirable because these assemblies can unfold new properties that differ from those exhibited by their individual...

Poly(lauryl methacrylate) films containing Au@Ag@SiO2 nanoparticles and InP@ZnS quantum dots were prepared to investigate metal-enhanced fluorescence in polymer composites.
