An overview on photonic detection of substances in bio-chemical label-free sensing applications based on receptors combined with multimode plastic optical fibers (POFs) will be presented in this webinar organized by the Photonic Detection Technical Group. Nunzio Cennamo from the University of Campania Luigi Vanvitelli will give a talk focused on different kinds of POF sensors (intrinsic and extrinsic) exploiting various types of receptors and useful in several application fields. The sensor structures and the sensing mechanisms of different simple, highly sensitive, and low-cost POF probes will be reported and compared. Moreover, different kinds of chemical and biological receptors combined with POF probes, highlighting the advantages and disadvantages of each receptor, will be presented in detail. More specifically, the chosen POF sensing platforms, including low-cost and simple interrogation setups, will be described showing their ability to monitor specific receptors exploiting intensity variation techniques and plasmonic phenomena, as well. Finally, a prospect of future developments of biochemical sensors with multimode POFs will be discussed.
