Nanotechnology leads to better bone implants

A team of U.S. researchers has found a new and inexpensive way to create a nanowire coating for titanium surfaces used in bone implants. Their nanowire scaffolds can be used 'to create more effective surfaces for hip replacement, dental reconstruction and vascular stenting.' As said the lead researcher, 'We can...

Nanoparticles used to trap oil drops

Rice University researchers have found a new way to spontaneously assemble nanoparticles into bag-like sacs. Their 'nanobatons' could be used to clean up oil spills by trapping oil droplets in polluted waters. These nanoparticles could even be more useful for delivering drugs. The researchers found that 'ultraviolet light and magnetic...
