Question

Biosensors measure glucose concentrations between which of the following ranges?

(a) 10^-1 to 10^-2 M

(b) 10^-2 to 10^-4 M

(c) 10^-1 to 10^-4 M

(d) 10^-1 to 10^-7 M

The question was posed to me during an online exam.

I'm obligated to ask this question of Biosensors in section pH Meters and Ion Analysers of Analytical Instrumentation

Answer 1

Correct option is (d) 10^-1 to 10^-7 M

The best I can explain: Biosensors measure glucose concentrations between 10^-1 to 10^-7 M. It is linear in the range of 10^-2 to 10^-4 M.
