Abstract: A fiber-optic sensing apparatus, system, and method for characterizing at least one metal ion in a solution are provided. The sensing apparatus includes a fiber-optic sensor and a controller. The sensor includes an optical fiber with tilted grating in its core, and includes a conductive and surface plasmon resonance (SPR)-active coating assembly that allows the sensor to also serve as an electrochemical working electrode. The controller is electrically connected with the sensor, configured to provide an adjustable potential such that when the coating assembly is in contact with the solution, redox reactions of each of the at least one metal ion occur on an outer surface thereof, resulting in a detectable change of the surface plasmon waves generated in the fiber-optic sensor. Based on the change thus detected, identities and/or concentration of the at least one metal ion in the solution can be determined with high accuracy and sensitivity.
