Question

Blood glucose biosensor is an example of ___________.

• A. Conduct metric biosensor
• B. Potentiometric biosensor
• C. Amperometric biosensor
• D. None of the above

Answer 1

Answer: (C)

Amperometric biosensor

Amperometric biosensors are biosensors which function by the production of a current when a potential is applied between two electrodes. One of its application is the determination of glucose concentrations by the use of an immobilised glucose oxidase membrane. Reaction results in a reduction of the oxygen concentration as it diffuses through the biocatalytic membrane to the cathode, this being detected by a reduction in the current between the electrodes

So, the correct answer is option C.
