UW-Madison spinoff gets FDA OK for bacteria-killing wound dressing
By David Tenenbaum, UW-Madison
Imbed Biosciences today received clearance from the Food and Drug Administration to market its patented wound dressing for human use. The dressing it calls Microlyte Ag is a sheet as thin as Saran Wrap and can conform to the bumps and crevices of a wound, says company CEO Ankit Agarwal.
The dressing is now cleared by the FDA as a class II medical device, for prescription and over-the-counter use.
Like many dressings now used to treat burns and other persistent wounds, Microlyte Ag contains silver to kill bacteria – but in much smaller quantities.
“Silver is an excellent antimicrobial agent,” says Agarwal, a co-founder of the company in the Madison suburb Fitchburg, “as it is active against a broad range of bacteria and yeast. But the large silver loads found in conventional silver dressings can be toxic to skin cells.

This chronic pressure sore on an Irish wolfhound received conventional treatment for more than three months at the UW–Madison School of Veterinary Medicine.
That kill ratio even appeared in tests against some of the nastiest hospital-acquired superbugs, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococcus. Read more …
