Question

The signal produced due to interaction of analyte with biological material is converted into signal which can be easily quantified by

• A. Biorecognition component
• B. Biological transducer
• C. Electronic system
• D. None of the above

Answer 1

The correct option is B Biological transducer

Biosensors are the analytical instruments that measures the concentration of analyte present in the sample by specific interaction with the biomolecules which are immobilised in the device. They recognise and interacts with the analyte producing signal which is detected by a biological transducer. The transducer converts the generated signal, due to specific molecular interaction, into an electrical signal which is then amplified by an amplifier and is measured. Therefore the correct answer is option B.
