Zinc or titanium oxide nanosurfaces can reduce the presence of bacteria on implants, according to research at Brown University, Providence, R.I. Zinc oxide is a well-known antimicrobial agent. Titanium oxide is commonly used in implants. Engineers took nanoparticles of these ceramics and pressed them into dime-sized discs.

They then took microparticles of these same materials and made more discs. Nanostructured surfaces had bumps that measured only 0.023 microns in diameter, while microstructured surfaces had bumps that measured about five microns in diameter. Under a ...
