In this work, fabrication of Localized Surface Plasmon Resonance based fiber optic sensing probe for cadmium detection in an aqueous solution is reported. Multimode fiber-photonic crystal fiber-multimode fiber structure coated with gold nanoparticles make up this probe. The proposed sensor's sensitivity is 1.564 nm/ppm. Furthermore, the sensor is small in size, immune to electromagnetic interference, making it ideal for a wide range of harsh environments and real-time measurement.

In this study, a fiber optic sensing probes based on localized surface Plasmon resonance was presented to detect various Heavy metal zinc concentrations in an aqueous solution. The fiber optic sensing probe consists of a single mode fiber-coreless fiber-single mode fiber structure coated with a 40 nm thickness of gold nanoparticles - polyvinyl pyrrolidone using an immersion method. The results obtained in the experiment showed that the sensor's sensitivity is 1.38 nm/ppm in the range of 0 to 6 ppm concentrations.
