A highly sensitive and selective method was developed for simultaneous detection of uric acid (UA), xanthine (XA) and hypoxanthine (HX) based on a 1,3,6,8-pyrene tetra sulfonic acid sodium salt functionalized nitrogen-doped graphene (PyTS-NG) composite. The material was synthesized by using a facile ultrasonic method via π-π conjugate action between 1,3,6,8-pyrene tetra sulfonic acid sodium salt (PyTS) and nitrogen-doped graphene (NG) mol. Compared with pristine NG, the material had better dispersivity and conductivity, which might be attributed to a large number of edge-plane-like defective sites on the surface of PyTS-NG that would accelerate electron transfer between electrode and species in solution The surface morphol. was characterized by SEM and TEM. The electrochem. behaviors of UA, XA and HX on the surface of PyTS-NG were studied by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Under the optimized condition, the linear ranges for the determination of UA, XA and HX were 9-1000, 8-800 and 8-200 μM, with the detection limits (S/N = 3) of 0.331, 0.0838 and 0.231 μM, resp. Also, the practical application of the present method was evidenced by determining UA, XA and HX in human blood serum and urine samples.
