Cambridge, Mass—Minute, "nanoscale" devices could lead to a new future in medical diagnostics, detecting proteins, viruses, or DNA in a highly sensitive and selective manner from blood and other bodily fluids in a matter of minutes, says Charles Lieber, PhD, a professor of chemistry at Harvard University, Cambridge, Mass.

While such a prediction may sound like a pipe dream, work on such biological sensors by Lieber and members of his laboratory suggests that these tiny devices could one day help transform diagnostic medicine. Lieber, who holds more than 25 patents for various fundamental aspects of nanotechnology and its applications, is also a scientific founder of a nanotechnology company, Nanosys Inc, in Palo Alto, Calif.

GROWING NANOWIRES

Lieber’s team fashions their electronic devices from silicon nanowires, some of which are only a few atoms thick. They grow nanowires in the laboratory, position them across contacts on a thin plate . . . [Full Text of this Article]
