A novel molecularly imprinted impedimetric sensor for melamine determination

► We developed a novel MIP impedimetric sensor for melamine determination. ► The sensor was fabricated by electrochemical polymerization of 2-MBI MIPs films. ► The sensor is reusable and has great improvement in sensitivity and selectivity. ► It is a fast and real-time method for the detection of melamine in real samples. ► It is an effective method to monitor nonelectrochemically active substances.
