Voltammetric Determination of Uric Acid in Clinical Serum Samples Using DMF Modified Screen Printed Carbon Electrodes

Figure 2

Differential pulse voltammetry recorded in 0.1 M PBS (pH 7) in presence (b and c) and absence (a) of 1 mM uric acid using untreated SPCE (b) and DMF treated SPCE (c) at a scan rate of 10 mV/s, pulse amplitude of 240 mV, and pulse period of 100 ms.
