Wound treatment compositions include an oxidized cross-linked polysaccharide which has a chemically induced charge. Preferred polysaccharides are cross-linked dextrans. A charge is preferably provided by diethylaminoethyl groups (DEAE groups) or carboxymethyl groups. The oxidized cross-linked polysaccharide can be applied as a powder directly to a wound site. Alternatively, the oxidized cross-linked polysaccharide can be combined with a delivery vehicle to form a liquid or past to be applied to a wound site.
