The identification of handedness for single carbon nanotubes becomes possible by scientists from Peking University in China

In the past three decades, various optical spectroscopic techniques have been demonstrated to identify the chiral indices (n, m) of carbon nanotubes unequivocally even at the single-tube level. However, the accurate characterization of the handedness via optical spectroscopy has been unrealizable for single nanotubes. Here, we developed the Rayleigh scattering circular dichroism to fulfil the dream of complete structure identification of both chiral indices and handedness for single nanotubes.
