NOVELTY - The utility model claims a surface flying vertical graphene biosensor, comprising: a circuit board, a ceramic substrate, a vertical graphene electrode, a conductive adhesive line; the vertical graphene electrode is set on the ceramic substrate, the circuit board is provided with a groove, the ceramic substrate is fixed in the groove, two ends of the conductive glue line are respectively connected with the vertical graphene electrode, the circuit board is connected with the circuit; the height difference between the surface of the vertical graphene electrode and the surface of the circuit board in the ceramic base body is 0.2 +/ - 0.1mm; the groove is matched with the ceramic substrate. The utility model uses conductive glue line to realize the conduction between the circuit of the graphene electrode and the circuit board, the production process is reduced, which effectively reduces the production cost, and can effectively avoid the oxidation caused by the metallized hole, erosion, the process difficulty is large, the resistance deviation is large, it can effectively reduce the detection time and further reduce the cost.
