▎ 摘　　要

NOVELTY - The biosensor has a glass substrate whose two sides are formed with ITO part. The ITO part is covered on a pole. A non-glass substrate is provided with graphene and the ITO part that are located on two sides of graphite alkene part. The ITO part of a capacitor is covered with graphite gasket PET that is formed with an upper sputtering gold film. The upper sputtering gold film is covered on a PET substrate. Silicon-on-insulator glue is formed on a sample tank in the glass substrate. An electrode is connected with the capacitor. Thickness of the film is about 150 nm. USE - Graphene capacitor biosensor. ADVANTAGE - The biosensor realizes detect limit of adenosine triphosphate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene capacitor biosensor manufacturing method (2) a graphene capacitor biosensor detecting method. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating an operation performed by a graphene capacitor biosensor.
