Production and property of antimicrobial chitosan fibers

This study used AgNO_3 solutions to treat chitosan fibers.Since the amine groups in the chitosan have chelating abilities,silver ions are absorbed onto chitosan fibers.When the silver-contained fibers are in contact with normal saline,the silver ions are released into the solution,acting as an antimicrobial agent.Experimental results show that the silver-contained chitosan fibers have much better antimicrobial effect than the untreated chitosan fibers.
