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 control the length, the height, the pore openings and the pore volumes within the nanowire scaffolds’ by varying the time, temperature and alkali concentration in the reaction,’ who added that the process was also extremely sustainable, requiring only that the device be rinsed in reusable water after the heating process. These **nanowire** scaffolds might also be used in hospitals or in meat-processing plants to kill **bacteria**. For more information "ZDnet":[ http://blogs.zdnet.com/emergingtech/?p=677]
