Construction of an Amperometric Cholesterol Biosensor Based on DTP(aryl)aniline Conducting Polymer Bound Cholesterol Oxidase

ÇEVİK, Emre | CERİT, Alaaddin | GAZEL, Nilay | YILDIZ, Hüseyin Bekir

In this study, an amperometric cholesterol biosensor was constructed based on cholesterol oxidase immobilized on a conducting 4-(4H-dithienol[3,2-b:2’,3’d]pyrrole-4)aniline polymer, (DTP(aryl)aniline). Glassy carbon electrodes were covered with P(DTP(aryl)aniline) which is used for the wiring of enzyme to the electrode surface by using electro-polymerization. The electron transfer was successfully made by the bio-catalytic activity and possession of the unique morphology of the polymer allowed efficient immobilization of the cholesterol oxidase enzyme. Analytical performances, linear range, de ...Daha fazlası

Enzyme‐Based Biosensors in Food Industry via Surface Modifications (Chapter 7)

GAZEL, Nilay | YILDIZ, Hüseyin Bekir

Enzyme technology has received great attention with improvements in biological remediation techniques. Enzyme-based biosensors can qualify as a measuring system as they permit the detection of biological events by detecting biochemical changes in biological processes. Advantages of biosensors are identification of even small quantities, cost effectiveness, and requirement of less power and less volume for identifying a wide linear range for usage [1]. Moreover, biosensors have high sensitivity, selectivity, and good response time for different kinds of applications.
