| Abstract: | An electrochemical bionic sensor for cholesterol detection was developed with molecular imprinting self-assembled film deposited on the screen printed gold electrode. The electrochemical characteristics of the electrode during modification were studied by cyclic voltammetry technique. The response of the sensor to the concentration of cholesterol was detected by chronoamperometric measurements. Cholesterol between 0 and 700nM were detected by this sensor. The linearity range is from 100 to 700 nM with the sensitivity of -2.4nA/μM. |
