Abstract :
The oxidation of dopamine was studied with differential pulse voltammetry at both Pt/PEDOT-PB modified electrode and Pt/PEDOT-PB microelectrode in the presence of ascorbic acid. The results show a detection limit of 10μM in the lack of ascorbic acid and 40 μM in the presence of ascorbic acid. The paper also present a diagnostic system at conceptual level with disposable biosensors able to collect brain probes or to be implanted to study and treat neuromotor disorder based on dopamine detection.
