Electrochemical polarization provides a practical means to enhance the typically sluggish electrochemical kinetics of screen‐printed electrodes. This study introduces an electrochemically deposited poly(amino acid) modification on screen‐printed carbon electrodes (SPCE) for the concurrent detection of Vitamin C (VC) and Paracetamol (PA). The poly(a...
