*************************
Researchers at MIT have found that
carbon nanotubes wrapped with a
small piece of DNA can serve as
highly sensitive biological sensors
for detecting single molecules in
living cells in real time, at a
sensitivity that far exceeds that of
fluorescent dyes, the standard tool
for molecular imaging. The sensors
could eventually be used to monitor…

Flawed nanotubes could be perfect
silicon replacement

*************************
Oak Ridge National Laboratory
scientists have have discovered that
a circuit of nanotubes can only
guide a current if some of the tubes
carry structural defects. Carbon
nanotubes are better conductors than
silicon at transmitting charge,
which means nanotube circuits could
boost computing speeds while
reducing chip size. Structural
defects,…
