A novel amperometric immunosensor for determination of human serum chorionic gonadotrophin (hCG) was constructed by immobilizing hCG antibody with nano-gold and chitosan (CHIT) hybrid film electrochemical co-deposited on a glassy carbon electrode. The fabricated procedures and electrochemical behaviors of proteins on such an interface were characterized with electrochemical impedance, cyclic voltammetry...
A novel strategy for the preparation of reagentless immunosensor for rapid determination of α-1-fetoprotein (AFP) in human serum has been developed. The immunosensor was prepared by immobilizing α-1-fetoprotein antibody (AFP Ab) onto the glassy carbon electrode modified by gold nanowires (Au NWs) and ZnO nanorods (ZnO NRs) composite film. Gold nanowires and ZnO nanorods were produced by an electrodeposition...
