abstract = "Cadmium, as a contaminant in drinking water, necessitates rapid and real-time detection due to its significant health implications. This study leverages the capabilities of optical fibers for swift and immediate detection, introducing a novel fiber optic technology for cadmium ion detection. The technology employs a MoS2-modified configuration consisting of single-mode fiber, no-core fiber, multimode fiber, no-core fiber, and single-mode fiber (SNMNS). The detection mechanism utilizes the evanescent field generated by the SNMNS structure, which interacts with MoS2 to adsorb cadmium ions(Cd2+), resulting in observable spectral changes. Fiber optic sensor performance was observed achieving a maximum sensitivity of 74.88 nm/μM and a limit of detection (LOD) of 0.77 nM. The proposed sensor's rapid and highly sensitive detection capabilities hold significant potential for the online monitoring of Cd(II) contamination in groundwater.",
