Question

Which of the statement for a biosensor is false?

(a) The linearity of the sensor should be ‘high’

(b) Value of the electrode response per substrate concentration should be low

(c) Chemicals Interference must be minimized for obtaining the correct result

(d) Response time should be low

I have been asked this question by my college professor while I was bunking the class.

I would like to ask this question from Biosensor Variants in section Biosensor Technology & Regulatory Issues in Biotechnology of Drug Biotechnology

Answer 1

Right choice is (b) Value of the electrode response per substrate concentration should be low

To elaborate: Linearity of the sensor should be ‘high’ for the detection of high substrate concentration. The sensitivity should be high to detect the substrate concentration. Selectivity should be high so that chemicals interference is minimized for obtaining the correct result.
