▎ 摘　　要

NOVELTY - Manufacturing electrochemical electrode based on laser-induced carbon material comprises (1) forming a laser-induced carbon material on the upper surface of the base substrate, (2) dripping a liquid material on the formed laser-induced carbon material, and (3) forming nanoparticles on the laser-induced carbon material by irradiating a laser to the liquid material, where the laser-induced carbon material is superhydrophilic. USE - The electrode is useful for capacitors, bacterial growth inhibition, selective biosensors, and plasmonic sensors. ADVANTAGE - The method is environmentally friendly.
