Carbon nanotubes, or CNTs, are hollow wires of pure carbon about 50,000 times narrower than the finest human hair -- but stronger than steel. CNTs have enormous potential in a variety of biological applications, including medical diagnostics and treatments. There's a problem, however, and until now it has been what technologists call a "stopper." For reasons not entirely known, CNTs are cytotoxic -- contact with them kills cells.
