▎ 摘　　要

NOVELTY - Sensor comprises a base substrate provided with a transparent electrode layer, a metal nanoparticles disposed on the transparent electrode layer, and a porous oxide graphene layer for directly covering surface of at least part of each of the metal nanoparticles and the transparent electrode layer and comprising multiple porous oxide graphene sheets. USE - The sensor is useful for detecting dopamine (claimed). ADVANTAGE - The sensor has improved electrochemically dopamine detection ability by hybridizing the porous oxide graphene layer and the metal nanoparticles together with the transparent electrode layer. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method of manufacturing the sensor for detecting dopamine. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the sensor for detecting dopamine.
