The strontium titanium oxide nanoparticles (STO NPs) was synthesized via a combustion method and characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX) and elemental mapping analysis. The redox behavior of the strontium titanium oxide modified glassy carbon electrode (STO/MGCE) was investigated through cyclic voltammetry, revealing a high electroactive surface area. The redox peaks were observed in 0.2 M phosphate buffer solution (PBS) of pH 7.0. The scan rate studies revealed that the process was governed by diffusion controlled. The pH dependence indicated that equal numbers of protons and electrons participated in the redox reaction and the limit of detection (LOD) and limit of quantification (LOQ) were obtained using varying analytes concentrations. Using cyclic voltammetry (CV) and differential pulse voltammetry (DPV), the STO/MGCE exhibited highly sensitive, individual and simultaneous detection of dopamine (DA) and uric acid (UA)
