DESCRIPTION:Prof. Jeremy Baumberg\, Cavendish Laboratory\, Dept. of Physic
 s\, University of Cambridge\, UKhttp://www.np.phy.cam.ac.uk/http://www.phy
 .cam.ac.uk/directory/baumbergj\nHow tightly can we confine light? For many
  years this was thought to be on the order of the optical wavelength\, but
  new insights allow us to squeeze it down to nearly a single cubic nanomet
 re. This opens up a new regime where we can watch single molecules\, and s
 culpt directly on the nanoscale using light. By combining metallic nano-ob
 jects at very close distances\, we squeeze light into these tiny dimension
 s at resonant wavelengths whose colour depends exquisitely on the nanoscal
 e geometry. Below 1nm gaps\, we detect the influence of quantum mechanics 
 in the optical signatures\, at room temperature and ambient conditions. We
  also show how it is possible to track single molecules\, and discuss the 
 implications for nano-chemistry and healthcare technologies.
