Preparation of Carcinoembryonic Antigen Immunosensor Based on Au Nanoparticles Loaded-Metal-Organic Frameworks

A novel electrochemical immunoassay for CEA was developed using Au nanoparticles loaded-metal-organic frameworks (Au NPs/Cu-TPA) as signal unit. Cu-TPA containing large amounts of Cu2+ ions can be used to achieve the detection of CEA.
