  • Molecularly imprinted conducting polymer film based aqueous amino acid sensors
    Patent number: 9239311
    Abstract: Molecularly imprinted conducting polymer (MICP) films were electro-polymerized on glassy carbon electrode having specific recognition sites for amino acid viz. L-tyrosine and/or L-cysteine. The amino acid templates in various imprinted films were ejected out by over-oxidation followed by washing and stabilization. Again, the template leached MICP films were modified with metal oxides [oxides of Cu2+, Hg2+, Pd2+, Au3+, Pt4+ etc]. The resultant leached MICP and metal oxide modified template leached MICP film based GCE will now selectively sense L-tyrosine and/or L-cysteine in aqueous media by direct and catalytic means respectively employing differential pulse voltammetric waveform. The sensitivity and selectivity of the sensors prepared by the invention are high and the stability is good, which will be widely used in clinical diagnostics, chemical industry, environment protection and other related fields.
