Mixed metal oxide based electrochemical sensing of inhibitory neurotransmitter serotonin in the presence of dopamine

Abstract

A mixed metal oxide modified electrode has been employed for the voltammetric determination of neurotransmitter serotonin in the presence of dopamine. The electrode was morphologically and electrochemically characterized using scanning electron microscope and cyclic voltammetry respectively. Differential pulse voltammetry were performed to measure the serotonin concentration at the electrode surface. A dynamic linear range of 0.2-52 μm was obtained. Viability of the sensor was tested in blood sample.
