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.
