摘      要：Non-enzymatic electrochemical sensor was developed for estimation of low-level ***/tungsten carbide(PIN/WC)nanocomposite was synthesized and used as an electroactive material to develop low-cost modified stainless steel plate electrode(SSPE).Surface morphology of developed electrode was characterized by scanning electron *** behavior of cholesterol was investigated through electron impedance spectroscopy,potentiodynamic polarization and cyclic voltammetry in 1-M KOH electrolytic *** quantification of cholesterol was studied by square wave voltammetry and differential pulse *** calibration plots between the cholesterol concentration and peak current were in linear relation with limit of detection of 1.23×10^(−6) mol L^(−1).The overall result reveals that developed PIN/WC/SSPE electrode has excellent performance for trace-level cholesterol estimation and can be further employed for cholesterol monitoring in blood serum samples.
