Primary focus of my inter-disciplinary research program is on synthesis of organic macro molecules, gold nanoparticles and functional materials like quantum dots to engineer models for surface plasmon resonance (SPR)-based fluorescence sensors. SPR is a light induced collective oscillation of electrons on a metal surface (typically a gold nanoparticle). The plasmon oscillation in turn generates a local electric field around the nanoparticle. The SPR of nearby nanoparticles can combine to generate even more concentrated electric field at their inter-particle gap, this phenomenon is called plasmon coupling. This local electric field can be utilized in several ways such as exciting the nearby fluorophores, monitor the aggregation of nanoparticles, enhancing the sensitivity of the biosensors, etc. The SPR on solid phase substrates has been broadly studied, but there is a huge limitation in the biological application of solid phase sensors that give us an opportunity to develop solution phase fluorescence sensors.
