Question

The amperometric transducers used in biosensors is used to detect _________________.

• A. Change in current during electrochemical oxidation or reduction
• B. Change in conductive properties of the sample solution
• C. Change in potential proportional to the concentration of analyte
• D. None of the above

Answer 1

The correct option is A Change in current during electrochemical oxidation or reduction

Amperometric transducers detect change in current as a result of electrochemical oxidation or reduction.

Typically, the bioreceptor molecule is immobilized on the working electrode commonly gold, carbon, or platinum.

The current produced is a direct measure of the rate of electron transfer.
