DESCRIPTION:Optical microresonators allow enhancement of light-matter inte
 ractions by confining light to micro and nanoscale geometries. In the firs
 t story\, I will describe how we can use optical microresonators as platfo
 rms for performing single-molecule photothermal spectroscopy. We will appl
 y this spectrometer to the conductive polymer\, PEDOT:PSS\, to understand 
 how the properties of the film derive from the properties of the individua
 l polymer molecules. In particular\, we will show how our single-particle 
 spectroscopy allows us to reveal long-range ordering that serves to enhanc
 e conduction and the mechanism of solvent annealing. In the second story\,
  I will describe how interfacing plasmonic materials with optical microres
 onators allows access to even greater enhancements by taking advantage of 
 the small mode volumes of the plasmonic resonators.
