Reporting in the Sept. 4 issue of Science, researchers at the University of Rochester in New York and at Universität Siegen in Germany describe their identification of constant, narrow-linewidth fluorescence from individual single-walled carbon nanotubes. The phenomenon may have uses in the development of single-photon emitters for quantum cryptography or of single-molecule sensors for biological applications. Using single-molecule fluorescence spectroscopy, the researchers excited individual 200- to 300-nm-long nanotubes at room temperature with 632.8-nm light from a HeNe laser.
