▎ 摘　　要

NOVELTY - The electrode has carbon material and nucleic acid. The carbon material is selected from a carbon nanotube, nanoporous carbon, a graphene, carbon nanohorn, a carbon nano coil, and fullerene. The carbon material makes an aqueous dispersion distributed by the nucleic acid contact. The carbon material and nucleic acid are electrodeposited on the electroconductive substrate. The mass ratio of the carbon material and the nucleic acid is 1:0.1-1:10. USE - Electrode used for sensors e.g., biosensor, used for measuring neurotransmitters. ADVANTAGE - Provides an excellent bond strength between a conductive substrate and a carbon material. Generation of rust is prevented. Provides an easy manufacturing method for electrode, without preparing a large-scale apparatus, since chemical vapor deposition method or laser irradiation, are not required. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a manufacturing method of electrode for sensors. DESCRIPTION OF DRAWING(S) - The drawing shows the photographic view of a carbon nanotube that is electrodeposited by the anode surface.
