Nanotube Flickering Reveals Single-Molecule Rendezvous


June 7, 2007

News thumbnail Bruce Weisman and Laurent Cognet In this week's issue of the journal Science, French and U.S. researchers describe a new technique that allowed them to zoom in and observe quantum quasiparticles called excitons on individual carbon nanotubes. The team, which was led by Rice University chemist Bruce Weisman and University of Bordeaux physicist Laurent Cognet, found that each exciton travels about 90 nanometers and visits around 10,000 carbon atoms during its 100-trillionth-of-a-second lifespan.
