dc.description.abstractIn this work we propose electrochemical lossy mode resonance (eLMR) as a powerful method for the detection of manganese (Mn) ions. The sensor is based on a simple planar waveguide (sodasingle bondlime glass coverslip) coated with a thin layer of indium tin oxide (ITO) to obtain an optical resonance effect. Simultaneously, the ITO layer served as the working electrode in the cathodic stripping voltammetry (CSV) of Mn. The eLMR sensor is capable of simultaneously performing electrochemical (EC) and optical measurements, specifically lossy mode resonance (LMR), to monitor the growth of the adsorbed Mn layer on the ITO electrode and the electrochemically modulated diffusion layer. For Mn2+ ions, a limit of detection (LoD) of 1.26 ppb has been demonstrated using the EC method, whereas the optical method exhibited a LoD of 67.76 ppb. The results obtained indicate significant potential for application in molecular electrochemistry and studies focused on electrified interfaces.es_ES
