The nanocrystalline coating of pure silver delivers antimicrobial barrier activity within 30 minutes - faster than other forms of silver. NUCRYST Pharmaceutical's antimicrobial technology is able to produce silver-coated polyethylene films that can release an effective concentration of silver over several days. Thus, as silver ions are consumed, additional silver is released from the dressing to provide an effective antimicrobial barrier. This patented silver-based antimicrobial technology can be applied to a wide range of medical devices including wound dressings, certain types of catheters and various implants to prevent infection. This technology was first applied to burn wound dressings because burns present a very severe risk of infection.- Acticoat, 5" x 5" Dressing, 5/bx, 5 bx/cs (US Only)
