Stability Investigation Of Electrochemical Laser Scribed Rgo Sensors For Nitrite Detection

Herein, we propose a new procedure to fabricate electrochemical laser scribed reduced graphene oxide rGO sensors with optimized methodology in order to enhance the stability of the obtained electrodes by treating a PET flexible substrate with plasma treatment then immersing it in Poly (diallyldimethylammonium chloride) polymer solution. Several testes are made to prove the enhancement such as electrochemical testes by running cyclic voltammetry. The final electrodes showed good capacity to nitrite (NO2-) detection with an acceptable long-term stability.
