Metal Nanoparticles Based Electrochemical Biosensors for Cholesterol

Abstract

Electrochemical biosensors (EBS) have recently gained much attention in the field of health care for the management of cholesterol (CHO). This review comprises a report on the modification of electrode surfaces with metal nanoparticles (MNP) for selective and sensitive sensing of CHO. Quantitative analysis of cholesterol is carried out with the use of the amperometric data of linear calibration plot. A good synergistic between MNP of working electrode (WE) and CHO give fast electron transfer and precised electrochemical detection of CHL.
