Title: Surface plasmons for high sensitive spectroscopy and super-resolution microscopy

Metal nanoparticles (NPs) exhibit unique optical responses due to the collective oscillations of the electron gas in the conduction band of the metal, termed as surface plasmons (SPs), of which frequency depends strongly on the element, size and shape of the NPs. SPs can create regions of concentrated fields, ‘hot-spots’ due to the localized SPs resonance, which can be used for high-sensitivity surface enhanced spectroscopy and high-resolution microscopy. In this lecture, use of SPs for spectroscopy and microscopy will be discussed.
