Question

Which of the following is a characteristic of calorimetric biosensors?

(a) Detects the change in light adsorption

(b) Detects the photon out for luminescent

(c) Detects the movement of electrons between electrodes

(d) Detects the angle at which electrons are emitted

The question was asked in semester exam.

This question is from Biosensor Variants in portion Biosensor Technology & Regulatory Issues in Biotechnology of Drug Biotechnology

Answer 1

Right answer is (a) Detects the change in light adsorption

The explanation is: Calorimetric biosensors measure the changes in the colour. It measures the changes in light absorption. Many enzymes catalysed reactions are exothermic. The change in temperature can also be detected by the transducer.
