Abstract
A highly sensitive method is proposed for the simultaneous determination of dopamine and tyrosine using a Ti3C2 nano layer modified screen printed electrode. The electro-oxidation of dopamine at the surface of the modified electrode was studied using cyclic voltammetry, chrono-amperometry, and differential pulse voltammetry. Under the optimized conditions, the differential pulse voltammetric peak current of dopamine increased linearly with dopamine concentrations in the ranges of 0.5–600.0 µM, and the detection limit of 0.15 µM was obtained for dopamine.
