Question

In calorimetric biosensor, the temperature changes are measured by means of _________

(a) Ion-selective electrodes

(b) Clark oxygen electrode

(c) Thermistors

(d) Colorimetric test strips

I have been asked this question in class test.

This is a very interesting question from Calorimetric Biosensors topic in chapter Biosensors of Enzyme Technology

Answer 1

Correct answer is (c) Thermistors

To explain: The temperature changes are usually determined by means of thermistors at the entrance and exit of small packed bed columns containing immobilised enzymes within a constant temperature environment. Ion-selective electrodes, clark oxygen electrode and colorimetric test strips are used in potentiometric, amperometric and optical biosensors respectively.
