Two-dimensional transition metal dichalcogenides (2D TMDs) have gained considerable attention from the scientific community for their various applications thanks to their remarkable chemical, physical, optical and electronic properties. In this study, MoS2 nanosheets were synthesized using a kitchen blender with the assistance of a surfactant so-called Pluronic F127 through a shear-exfoliation process. Different techniques were used to characterize the chemical composition, nanostructure, and electrochemical properties of the synthesized MoS2-F127 as well as Pt modified with MoS2-F127 (Pt/MoS2-F127) electrode. The Pt/MoS2-F127 electrode combined with differential pulse voltammetry was used for the electrochemical detection of homovanillic acid (HVA) in the presence of common interferents in urine. The study provides a new approach to discriminate the electrochemical signal of HVA and UA which lead to higher selectivity of the sensor.
