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.
