Abstract :
Cholesterol oxidase was immobilized on the 10-Carboxy-1-decanethiol (CDT) self assemble monolayer prepared on the gold (Au) substrate. These electrodes have been characterized using contact angle (CA) measurements, electrochemical techniques and atomic force microscopy (AFM). These ChOx/CDT/Au electrodes have been utilized for the estimation of cholesterol concentration in solution using the surface plasmon resonance (SPR) technique.
