Maintaining normal biomolecular levels in the human body plays a crucial role controlling various diseases. In this work, we designed portable microelectrochemical sensor based on laser-induced graphene (LIG) for simultaneous determination of ascorbic acid (AA), dopamine (DA), and uric (UA). A simple electrode surface modification strategy, potentiostatic polarization an alkali solution, was applied to functionalize LIG with aim enhancing electrocatalytic activity, conductivity, wettability. After electrochemical pretreatment, modified displayed significantly enhanced activity toward AA, DA, UA, well-separated characteristic oxidation peaks each analyte, thus achieving their detection without further by nanomaterials. Differential pulse voltammetry (DPV) determining these three analytes. Under optimal conditions, calibration curves were obtained ranges 10–5000 μM, 0.1–6000 10–8000 nM limits (S/N = 3) 1.43 6.83 nM, 1.07 respectively. The achieved reliable satisfactory results detecting UA actual urine samples, demonstrating significant application prospects health monitoring clinical diagnosis.
