Different methods of adding silver into wound dressings

In order to find effective methods to combine silver ions with base material,this paper analyzed the structures and properties of various silver compounds currently available on the international market,and introduced the preparing methods of various silver-contained wound dressings on the world market.Results showed that since it has a low antimicrobial activity,metallic silver should have very fine particle size and be incorporated into the base material on its surface so that silver compounds can exchange ions with exudates from the wound,making silver ions easy to release.Because of the large varieties of silver compounds and base materials,silver-contained wound dressings differ significantly in their functional properties.
