Nanotextured Implant Materials: Blending in, Not Fighting Back
April 9, 2007
Texture turns out to be nearly as important as chemistry when designing materials for use in the human body. In two related experiments, Brown University engineers Thomas Webster and Karen Haberstroh found that cells responded differently to materials with identical chemistry but different surface textures. On both titanium and polymer materials, nanoscale surface textures yielded a more natural, accepting response, while microscale patterns spurred a rejection response.
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) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
