Abstract
A simple and efficient molecularly imprinted sensor (MIPs/GR/GCE) was firstly prepared by electropolymerization of pyrrole in the presence of bovine serum albumin (BSA) in an aqueous solution based on a graphene modified glassy carbon electrode for the selective recognition of bovine serum albumin. The prepared sensor was characterized by differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS), in which [Fe(CN)6]3−/4−was used as an electrochemical active probe. The results showed a wide linear range from 1.0 × 10-3to 1.0 × 10-9g/mL. And the imprinted biosensor indicated excellent selectivity and high sensitivity.
