Surface Enhanced Spectroscopy

SES is the technique which involves a reaction of chemical interactions and enormous electromagnetic fields near a surface. It is very sensitive as well as selective and has been exploited in physics, chemistry and biology and medicine. This method is one of the most enormously developing and important technique in the present world. In this method they use Nano sized roughened metal surfaces which are basically made of silver and gold. When these metals made to get excited under the presence of laser, their surface charges get drive thus creating a highly localised light field (plasmonic).
