Abstract

Transition metal (e.g., silver and copper) derivatized phosphorylated polysaccharides (cellulose, starch, gauze) provide antimicrobial and elastase sequestration properties to wound dressings, and the wound dressing have enhanced water sorption and elastase sequestration when used with alginates. Wound dressings with alginates (e.g., silver alginate, crosslinked alginates, etc.) provide enhanced wound fluid absorption as well as elastase sequestration.

Claims

exact text as granted — not AI-modified
1 - 5 . (canceled) 
     
     
         6 . A wound dressing comprising:
 a phosporylated polysaccharide substrate complexed with at least one transition metal; and   an alginate coating wherein said alginate coating is crosslinked, wherein the alginate coating comprises an alginate selected from the group consisting of ammonium alginate, sodium alginate, potassium alginate, magnesium alginate and alginic acid.   
     
     
         7 - 9 . (canceled) 
     
     
         10 . The wound dressing of  claim 6 , wherein the alginate coating comprises ammonium alginate.
