Summary: This work investigates the fabrication of sensor structures by splicing tapered/etched multicore fiber probes with multimode fiber and immobilizing them with gold nanoparticles and molybdenum disulfide nanoparticles to enhance sensitivity. The morphology of the nanoparticles is examined using high-resolution transmission electron microscopy, and the immobilized optical fiber sensor structures are characterized using scanning electron microscopy and SEM-EDX. The functionalization of the acetylcholinesterase enzyme over the nanoparticle-immobilized probe increases sensor specificity. The developed sensor probes are tested for detecting various concentrations of acetylcholine, and performance analyses are performed. The developed tapered fiber sensor exhibits a high sensitivity and wide detection range.
