  • Wound dressings containing complexes of transition metals and alginate for elastase-sequestering
    Patent number: 8187626
    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.
