Detection of Ascorbic Acid in Tears with an Extended-Gate Field-Effect Transistor-Based Electronic Tongue Made of Electropolymerized Porphyrinoids on Laser-Induced Graphene Electrodes

Detection of Ascorbic Acid in Tears with an Extended-Gate Field-Effect Transistor-Based Electronic Tongue Made of Electropolymerized Porphyrinoids on Laser-Induced Graphene Electrodes

Porphyrinoids are suitable sensitive materials for potentiometric electronic tongues. In this paper, we take advantage of these properties to develop an electronic tongue using an extended-gate field-effect transistor as a signal transducer. The sensitive films were made of different porphyrins and...
