NOVELTY - The utility model claims a transparent graphene can be induced by surface plasma strip array structure, comprising a lining plate and graphene strip combination unit; the upper surface of the lining board is fixed with a regular arrangement of graphene strip combination unit, graphene strip combination unit comprises the size of the side strip A, a central strip and lateral strips B, side strips, a central strip and the side strip B; the side strip A and strip B longitudinal alignment are placed side by side, central strip horizontally placed between the side strips and lateral strips B, and the central strip is vertical to the lateral strips, strip B side. position of the filtering belt of the utility model can be randomly adjusted by the gate voltage, filter depth can reach good effect, and the device structure compared with the current similar metal structure is simple, can be manufactured by thin film deposition method; the pair of biological detection, use of filter and sensor is more flexible, and the effect is better.
