▎ 摘 要
NOVELTY - Sensor electrodes each comprise a carbon-based layer and a layer of graphene platelets. The layer of graphene platelets modifies surface properties of the carbon-based layer such that the sensor electrode with both carbon-based layer and layer of graphene platelets has a narrower distribution of electrochemical properties than sensor electrodes comprising carbon-based layer excluding layer of graphene platelets. USE - Sensor electrodes. ADVANTAGE - The sensor electrodes have improved physical property, electrical property, biochemical property and reproducibility. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of electrode apparatus. Screen-printing silver ink contact traces (310) Reference electrode (320) Sensors (330)
