It's got to be Guinness Book world record. A team of researchers has created a working radio from a single carbon nanotube that they say functions across a bandwidth widely used for commercial radio. Its application possibilities range from radio-controlled devices that could flow in the human bloodstream to a new generation of wireless communication devices.
"This breakthrough is a perfect example of how the unique behavior of matter in the nanoworld enables startling new technologies," says Bruce Kramer, a senior advisor for the National Science Foundation (NSF). The radio was developed at the NSF's Center of Integrated Nanomechanical Systems.
