Nanosheet Could Prevent Burn Infections

Aug-13-14 A new, nanonsheet material able to cling to irregular skin could provide a more effective treatment for burn victims.

The nanosheets are made by first spinning the biodegradable polymer poly(L-lactic acid) (PLLA) in a test tube of water, breaking the material down into smaller pieces. This mixture is then poured onto a flat surface, where the pieces overlap and merge to dry into a single sheet. The unique makeup of the nanosheet allows it to tightly cover even tiny bumps and irregularities (such as the wrinkles on a mouse's digit), and effectively block the Pseudomonas aeruginosa bacteria—a major cause of skin infections.

In tests, the nanomaterial protected wounds for a total of six days—twice as long as with just a dressing alone.
