In monitoring the metabolic activities of humans and plants, conventional ion sensors have faced challenges such as resolution limits and damage to biological tissues. In this study, we developed an ISM-OLAPS by laminating an ion-selective membrane (ISM) onto an organic light-addressable potentiometric sensor (OLAPS), which is composed of all-organic materials and is theoretically capable of multi-sensing and 2D imaging. The evaluation results showed favorable sensitivities for K and Na ion, confirming that ion selectivity can be realized even with a parylene insulation layer.
