Fund Project:

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.
