文摘Polysaccharide-based composite materials（beads） containing silver nanoparticles（AgNPs） were successfully prepared.Hydrogel beads acted as an efficient vehicle for Ag＊ delivery.Beads promoted the AgNPs protection and inhibited their aggregation.Antimicrobial assays showed that the beads/AgNPs concentration can be modulated to deliver an amount of Ag＊ necessary for kill Escherichia coli cells.
