Question

Which of the following is a characteristic of electrochemical biosensors?

(a) Detects the change in light adsorption

(b) Detects the photon out for luminescent

(c) Detects the movement of electrons between electrodes

(d) Detects the angle at which electrons are emitted

I got this question by my school principal while I was bunking the class.

I'm obligated to ask this question of Biosensor Variants topic in portion Biosensor Technology & Regulatory Issues in Biotechnology of Drug Biotechnology

Answer 1

Correct option is (c) Detects the movement of electrons between electrodes

Easy explanation: For a given applied current, electrochemical biosensors study the movement of the electrons in redox reactions detected when a potential is applied between two electrodes. Thus, these biosensors can detect the change of the electron flow due to any reaction,
