Abstract : Herein highlighting a molecular imprinted pyromellitic acid modified indium tin oxide electrode for the quantification of L-tryptophan. The quality and features of the modified electrode were in accordance with the basic characteristic features of a sensor in all perspectives. The morphological and the functional group identification of the electrode surface were done by scanning electron microscopy and infrared spectroscopy. The proposed electrode material exhibits prolonged stability with ease of handling for real sample analysis. The linear range of the fabricated electrode was noticed to be the highest linearity reported through a molecular imprinted electrode for the electrochemical quantification of L-tryptophan. The electrode has a linear range from 0.4 μM to 500 μM with lower detection limit of 0.1 μM. The sensitivity of the electrode was calculated to be 0.297 μM/μA/cm2.
