Potential applications of nanoparticles embedded U-bent fiber optic probe

As an emerging interdisciplinary, nanotechnology combined optical technology has drawn phenomenal attention in most of the fields. As a result, many novel sensors of nanoparticles (NPs) embedded U-bent Fiber optic probe have been developed. This paper deals about the spectacular growth of this novel strategythat is based on the evanescent wave signal and the NPs ability to tune LSPR (local surface plasmon resonance) adding more potential. A study has been made on its diverse applications ranging from parameters monitoring down to biomolecule detection till recent pandemic identification are discussed.
