▎ 摘　　要

NOVELTY - The sensor has a substrate whose surface is provided with a sensing layer. The sensing layer is composed of a graphene layer and a gold nano-particle film layer. The graphene layer is a wrinkle structure. The graphene layer surface is formed with a gold nano-particle film layer. Both sides of the sensing layer are provided with source electrodes and drain electrodes. A dopamine aptamer is fixed between the source electrode and the drain electrode. The guide member is used for guiding the connection rope connected between the unit blocks, so that the unit block is guided to move in the lane. USE - Three-dimensional pleated graphene field-effect transistor sensor for detecting dopamine for helping cell transfer pulse including a nanometre biosensor. ADVANTAGE - The three-dimensional pleats sensor graphene field-effect transistor has large specific surface area, has biological molecule binding sites, and has high sensitivity, good selectivity, high specificity and good safety characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing three-dimensional pleated graphene field-effect transistor sensor; and an application of three-dimensional pleated graphene field-effect transistor sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the manufacturing process of the three-dimensional pleated graphene field-effect transistor sensor for detecting dopamine for helping cell transfer pulse (Drawing includes non-English language text).
