Enhancement of Electrochemical Detection of Gluten with Surface Modification Based on Molecularly Imprinted Polymers Combined with Superparamagnetic Iron Oxide Nanoparticles

Dalawan Limthin et al.

Summary: Novel molecularly imprinted polymers (MIPs) functionalized with superparamagnetic nanoparticles (SPIONs) were successfully developed for gluten detection. The modified electrode surface morphology was characterized by scanning electron microscopy-energy-dispersive X-ray spectrometry. The performance of the MIP electrode was evaluated using cyclic voltammetry, amperometry, and electrochemical impedance spectroscopy. The MMIP electrode exhibited a dynamic linear range of 5-50 ppm, a detection limit of 1.50 ppm, and excellent selectivity, sensitivity, stability, and reproducibility.
