| Crynodeb: | Title screen Cholesterol plays a crucial role in the human body. High cholesterol level in blood is a marker of CVDs. Therefore, cholesterol determination techniques are necessary for clinical practice. Currently used cholesterol determination techniques involve enzymes or expensive and complicated equipment. Electrochemical techniques are widely spread in test-systems and sensors construction. Novel modification procedure for enzymeless cholesterol determination is suggested in this study. The electrochemical behavior of cholesterol on modified electrode was studied with the usage of cyclic and differential pulse voltammetry. Obtained concentration range is linear from 0.1 up to 100 mM a conditions close to physiological (pH=6.86) with a quantification limit of 0.01 mM. Besides, the electrode surface morphology and pH-effect were studied. The developed technique is promising for the rapid determination of total cholesterol in blood.
