Abstract
Laser-induced graphene was obtained from polyimide films by lasing with a commercial CO2 laser. Then porphyrinoids were electrosynthesized on the electrodes using cyclic voltammetry. These electrodes were employed as working electrodes in an extended gated field-effect transistor configuration. The array exhibits excellent sensitivity towards ascorbic acid and dopamine. Furthermore, artificial tears were tested with and without ascorbic acid as real samples.
