- Description
- Excessive usage of food additives needs to be extensively examined and regulated. Herein, we report the development of an exceptionally proficient and practical electrochemical sensor for the quantitative determination of 4-hexylresorcinol (4-HR) in shrimps using a molecularly imprinted conducting polymer. By electropolymerizing 2-aminothiazole (AT) on the surface of a carbon fibre paper electrode (CFP) in the presence of 4-HR imprinted polymer films were developed. Bulk-electrolysis was used to produce definite imprinting sites and regulate the release of 4-hexylresorcinol templates. Voltammetric study reveals that the synthesized conducting polymer has outstanding electroactivity towards 4-HR and enables quick electron transfer kinetics. This MIP sensor has a detection limit of 6.03 nM for 4-HR. The modified CFP electrode has been found to be extremely selective to 4-HR due to its intensive contact via intermolecular hydrogen bonding. The modified electrodes were characterized by Scanning Electron Microscopy, Fourier Transform Infrared spectroscopy, Optical profilometry, and X-ray Photoelectron Spectroscopy. 2022 Elsevier B.V.
