Question

Which of the following is false for a biosensor?

(a) Self-contained integrated device

(b) Capable of providing specific information

(c) Uses a biological recognition

(d) Don’t connect to a transduction element

The question was posed to me during an interview.

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

Answer 1

The correct answer is (d) Don’t connect to a transduction element

To explain: A biosensor is an integrated device which is capable of providing quantitative analytical information using a biological recognition element. This element will be in direct contact with a transduction element. An enzyme electrode is a biosensor. It’s a sensor that integrates a biological element with a transducer such that it can produce an electronic signal.
