چکیده
In the present work, a nanocomposite of two-dimensional WSe2 nanosheets with poly(3,4‑ethylenedioxythiophene (WSe2@PEDOT) was prepared by facile hydrothermal method and characterized in terms structural morphological analyses. This nanocomposite used to modify glassy carbon electrode for construction an electrochemical sensing platform simultaneous determination dopamine (DA) uric acid (UA) presence ascorbic (AA). It found that incorporation PEDOT into nanosheets exhibited enhanced behaviors electro¬catalytic activity against DA UA. Using differential pulse voltammetry (DPV) measurements, WSe2@PEDOT modified displayed wide linear detection ranges 16 466 µM 20 582.5 The also high selectivity UA major interference other interferent substances.
