Nanomodified Surfaces Seal Leg Implants Against Infection
March 22, 2011
Researchers at Brown University have created nanoscale surfaces for implanted materials that mimic the contours of natural skin. The surfaces attract skin cells that, over time, are shown to build a natural seal against bacterial invasion. The group also created a molecular chain that allows an implant surface to be covered with skin cell-growing proteins, further accelerating skin growth. Results are published in the Journal of Biomedical Materials Research A.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2012, its budget was $7.0 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives about 50,000 competitive requests for funding, and makes about 11,500 new funding awards. NSF also awards about $593 million in professional and service contracts yearly.
