Question

Which of the following technology is used for whole-blood monitoring in diabetes control?

(a) Amperometric biosensor

(b) Potentiometric biosensor

(c) Optical biosensor

(d) Calorimetric biosensor

I got this question in class test.

This is a very interesting question from Optical Biosensors and Piezoelectric Biosensors topic in division Biosensors of Enzyme Technology

Answer 1

Correct answer is (c) Optical biosensor

To explain: Optical biosensor is used for whole-blood monitoring in diabetes control. In this case, the strips include glucose oxidase, horseradish peroxidase and a chromogen. The hydrogen peroxide, produced by the aerobic oxidation of glucose, oxidizes weakly colored chromogen to a highly colored dye.
