Overview of optical biosensing techniques Academic Article uri icon


  • Commonplace optical biosensing techniques include the classical techniques of optical spectroscopy, polarimetry, and ellipsometry, in addition to more modern techniques such as surface plasmon resonance and guided waves. Currently state-of-the-art techniques under extensive investigation include whispering-gallery waves and surface-enhanced optical phenomena near metallic nanoparticles. A succinct overview of the fundamentals of these techniques accompanies remarks on commercial successes and research accomplishments.
