• strategy employing TiO2/GQDs was used to fabricate a sensitive voltammetric sensor for the determination of URI and HYP in real samples. The decoration of nanoscale TiO2 with GQDs can provide excellent electrode modification because of the combination of enlarged active surface area and strong adsorptive
