Abstract
An antibacterial wound dressing is based on or derived from gel-forming fibers such as carboxymethyl cellulose or alginate fibers having silver ions linked thereto at some but not all of the exchangeable sites such that the distribution of silver ions over the exchangeable sites is substantially uniform. The silvered fibers for the wound dressing can be prepared by contacting an assembly of precursor gel-forming fibers having exchangeable sites under conditions which do not cause irreversible gelling of the fibers with an amount of a solution containing silver ions so as to link silver ions at some but not all of the exchangeable sites, the whole of the assembly of precursor gel-forming fibers being contacted essentially simultaneously with the entire solution containing silver ions.
