Nano World: Diamond-nanotube composites
Charles Q. Choi: A novel hybrid material composed of diamond and carbon nanotubes could find use in everything from biological-weapons detectors to flat-panel displays, experts told UPI's Nano World.
The hybrid material could make for coatings as hard and low friction as diamond while less brittle. The composites might also find use in flat panel displays: the diamond may keep the carbon nanotubes from unraveling as they do normally when scientists attempted to make displays made from nanotubes alone. And the diamond-carbon nanotube material could also find use in bioweapons detectors, with nanotubes bound to biomolecules acting as the sensor elements and the diamond behaving as an exquisitely sensitive electrode.
