New material shows promise for wound treatment

Treating skin wounds, especially pressure ulcers, has become easier over the years with the advent of new commercial dressings. But a group of scientists have developed a material that not only hastens the healing of such wounds but also prevents bacteria from sticking.

The researchers recently published the results of their study in Applied Materials & Interfaces, a journal of the American Chemical Society (ACS).

In a press release posted on the ACS website, the researchers explained that they took a porous dry film similar to those already on the market, and attached to that film structures called zwitterionic copolymers, which have successfully been used to keep bacteria from sticking to blood-filtering devices.

The resulting biomaterial was able to keep the wound environment moist yet breathable while also being slick enough to prevent bacteria from sticking.

In studies done on mice, the researchers noted that there was complete regrowth of skin and total formation of new connective tissues after only 14 days.
