PolyMedix Inc. says it has received a $150,000 grant from the National Science Foundation to help develop sutures that resist infections.

The Radnor biotech company said that grant, which begins July 1, will support six months of research in one of its compounds that seems well-suited for use in sutures.

Surgical site infections are the third most common hospital-acquired infection, the company said, and because more than 60 percent of them are at the incision site, sutures coated with an antibacterial agent could aid in reducing them.

Nicholas Landekic, PolyMedix president and CEO, said that this was the company's 12th grant or research contract, but the first grant from the National Science Foundation.    - Roslyn Rudolph
