Question

Which of the following is a characteristic of piezoelectric 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 have been asked this question in quiz.

The above asked question is from Biosensor Variants topic in section Biosensor Technology & Regulatory Issues in Biotechnology of Drug Biotechnology

Answer 1

Right option is (d) Detects the angle at which electrons are emitted

The best I can explain: Piezo-electric devices uses gold to detect the specific angles of the emitted electron waves. When the substance is emitted to the laser light it will emit electron waves.  These waves vibrate under the influence of an electric field.
