| Abstract: | The present invention relates to developing Multilayer coating enabled flexible electrodes for lead detection. The multilayer coating consists of copper (Cu), diamond- like carbon (DLC), and ternary nanocomposite of reduced graphene oxide, polynorepinephrine, and alanine (GAP) on the surface of flexible substrate. Cu and DLC coating is developed using magnetron sputtering and plasma-enhanced chemical vapor deposition. Whereas a GAP ternary nanocomposite is applied using drop casting method. Electrochemical studies were performed to investigate the electrochemical performance of the developed GAP/DLC/Cu/PP multilayer composites. The results reveal nearly 3-fold higher peak current than Cu/PP with excellent stability. Cu and DLC materials impart surface conductivity and electrochemical activity, while the functional moieties within GAP facilitate lead detection through chelate formation with lead ions. The developed flexible electrode-based sensor achieves a 6.42 ?A/ppb sensitivity and 0.5 ppb detection limit which is lower than the permissible limit given by WHO and BIS guidelines. |
