This chapter discusses the unique approach's phenomenal expansion, which is based on the evanescent wave signal and NPs' capacity to tune LSPR (local surface plasmon resonance), which offers greater potential. . This also includes the fabrication process of nanoparticles embedded U-bent Fiber optic probe (NP@UFOP) along with the merits of the probe from that of the other optical probes. A study has been made on its diverse applications ranging from parameters monitoring down to biomolecule detection till recent pandemic identification that are discussed in the chapter. 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 embedded U-bent Fiber optic probe have been developed.
