SUMMARY:Extreme Nanooptics With Precision Molecular Assembly - Prof. Jerem
 y J Baumberg\, (University of Cambridge\, UK)

CONTACT:Dr Anna Ott
DESCRIPTION:Coupling between coinage metal `plasmonic' nano-components gen
 erates strongly red-shifted optical resonances combined with intense local
  light amplification on the nanoscale. I will show how we now create ultra
 low volume plasmonic cavities trapping light to the atom scale <1nm^3\, an
 d are routinely able to watch individual molecules and bonds vibrating. Us
 ing DNA origami we couple 1-4 dye moleculestogether optomechanically\, and
  produce strong-light matter coupling that changes their quantum emission 
 properties. We also watch redox chemistry in real time\, watching single e
 lectrons shuttle in and out of single molecules\, as well as layered mater
 ials confined in the same gap. Prospective applications range from (bio)mo
 lecular sensing to fundamental science. I particularly focus on applicatio
 ns to nanomachinery actuation by light.
