Then, we introduce our new method to determine RET rate between molecule via Plasmon Resonance Energy Transfer Logan Liu 3Optical absorption spectroscopy at visible wavelength range is a common analytical method in chemistry and biology; however, the low sensitivity and spatial resolution of this technique prohibit its application in microscopic or nanoscopic biomolecular analysis and in-vivo cellular/molecular imaging. In this study, we overview resonance energy transfer between molecules in the presence of plasmonic structures and derive an explicit Förster-type expression for the rate of plasmon-coupled resonance energy transfer (PC-RET).
