DESCRIPTION:Speaker: Jeremy Baumberg\nhosted by Rafal Klajn\nAbstract: Our 
 ability to trap light into extreme nanoscale gaps between coinage metals u
 sing plasmonics now enables routine vibrational spectroscopies of molecula
 r monolayers\, even within active molecular electronics devices. We show h
 ow light-induced forces pull single adatoms from metals\, to create ‘pic
 ocavities’ which confine light to volumes < 1nm3. Such thousand-fold str
 onger optical forces depend on nearby molecules as well as temperature and
  local optical field\, and offer a route to single-molecule optical tweeze
 rs. Confinement allows new breakthroughs in surface-enhanced Raman scatter
 ing (SERS) allowing low-cost robust approaches to sensing of many metal-mo
 lecule processes as well as trace analytes in solution or vapour. These ha
 ve applications in healthcare technologies\, environmental protection\, ag
 ritech\, and security\, which I will explore.
