▎ 摘　　要

NOVELTY - The micro-electrode has a main portion which is formed by combining platinum silk and graphene. The diameter of platinum silk is 100-500 (mu)m, and deposition length of platinum silk is 1-3 cm. Graphene depositing electric potential is 0.8 to 1.0V. USE - Micro-electrode. ADVANTAGE - The electrochemical and enzyme are able to be rapidly tested. The stability and lifetime of the sensor are improved effectively. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene alkene micro-electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view showing mirror image of porous graphene micro-electrode.
