A new type of three-dimensional (3D) electrochemical sensor was prepared by combining carbon nanotubes on graphene foam (GF/CNT) with molecularly imprinted polymer (MIP), which affords simultaneous identification and quantification towards target compound. The hybrid sensor shows ultralow detection limit of 6.67 × 10− 16 M (S/N = 3), wide range of 2 × 10− 15 M to 1 × 10− 12 M, and superb selectivity for dopamine (DA) detection.
