Metal nano-bumps could improve artificial body parts
Biomedical engineers at Purdue University have proven that bone cells attach better to metals with nanometer-scale surface features, offering hope for improved prosthetic hips, knees and other implants. Conventional titanium alloys used in hip and knee replacements are relatively smooth – their surfaces possess bumps measured in microns – or millionths of a meter. Natural bone and other tissues, however, have rougher surfaces with bumps about 100 nanometers – or billionths of a meter – wide.
