Chitosan-organosilica hybrid decorated with silver nanoparticles for antimicrobial wearable cotton fabrics.

Functional cotton fabrics using silver-based nanoparticles (AgNPs) have attracted a lot of attention as a new generation of healthcare wearable textile. In this study, cotton fabrics were coated via impregnation with silver nanoparticles using chitosan (Cs) and (or) chitosan-organosilica (Cs-OSH) solutions as adhesives matrices. The physicochemical properties were studied using UV-VIS spectroscopy, and transmission electron microscopy (TEM) and scanning electron microscope coupled with energy-dispersive X-ray spectroscopy methods (SEM-EDX).
