A novel electrochemical sensor was presented for the determination of L-5-hydroxytryptophan (L-5-HTP) based on a graphene-chitosan molecularly imprinted film modified on the surface of glassy carbon electrode (GR-MIP/GCE). The morphology and composition of the imprinted film were observed in field emission scanning electron microscopy (FESEM), raman spectroscopy and fourier transform infrared (FTIR)...
A molecularly imprinted polymers (MIPs) microsensor was presented as a carbon fiber microelectrode (CFME) coating for specifically recognizing xanthine (Xan). The polymeric film was obtained based on the imprinted procedure of electropolymerization of pyrrole in the presence of the template molecule Xan by cyclic voltammetry, and template was removed by magnetic stirring. Under the optimum conditions,...
