Tóm tắt

Monitoring uric acid (UA) level in body fluids is of great significance for clinical diagnosis and treatment of related diseases. Herein, we introduce a simple smartphone-assisted colorimetric sensing platform for detection of UA. The experiment exhibited that the peroxidase-like activity of copper-doped Prussian blue (CuPB) could be enhanced by the doping of Cu element on Prussian blue. CuPB displayed excellent peroxidase-like activity and efficiently catalyze the oxidation of 2,2-diazo-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) in the presence of H
