The electrodeposited graphene (EGR) and cysteic acid (CA) composite (CA/EGR) was fabricated through an electrochemical method for the modification of glassy carbon electrode (GCE). The obtained detection linearity of isoniazid at the CA/EGR/GCE ranged from 0.1 to 200 μM with the detection limit of 0.03 μM (S/N = 3).
