This study aims to detect the target antigen by the composite film based on macroporous hexagonal carbon ferrochrome (MHCF) and graphene nanosheets (GNPs). Specifically, we will modify antigen-specific antibodies on the surface of MHCF, and study the electrochemical properties of MHCF/GNPS film under different conditions by cyclic voltammetry and impedance spectroscopy. We will also explore the impact of antigen-antibody interactions on its perance. The results of this study will provide theoretical and technical support for the development and application of reagent-free electrochemical immunosensors.
