In-situ detection of physical and chemical changes in plasmonic nanocavity

In-situ observation of light-induced physico-chemical changes is a long sought experimental approach to gain mechanistic understanding of the underlying fundamental processes. Here, we present experimental results that demonstrate the possibility of using plasmonic nanocavity for inducing and observing physical and chemical changes. This is demonstrated by monitoring photons scattered by a plasmonic nanocavity, in which materials of interest (organic and inorganic systems) are embedded.
