Also, in the treatment of cardiovascular diseases, prevention of restenosis (post stent placement) and lung diseases, nanotechnology offers great scope for early diagnosis and effective drug delivery. In the case of blood diseases, systemic cytotoxicity could be reduced by targetting drugs to lymphocytes. Nanotechnology offers such targeted drug delivery system. [Buxton, 2006]

Electronics

Nanotechnology will usher a quantum leap in computing. In fact, with nanotechnology quantum computing will be a reality very soon. Computers based on nanowires or nanotubes would have super-computing power but still be handheld. Carbon nanotubes are highly conductive and are better than copper. They also have semi-conducting properties. Thus far, the realization of building nanoscale electronic circuits using carbon nanotubes had been a problem. However, researchers at Caltech have already designed and built 'nanowire-based circuits'. Dr. Hongjie Dai, professor at Stanford University says "the move to CMOS with nanowires is important if nanowires are to be...
