There are different types of biosensors based on different principles. However, generally they are categorized as:

Optical biosensors

Potentiometric biosensors

Resonant Biosensors

Thermal-detection Biosensors

Ion-Sensitive Biosensors

Electrochemical Biosensors

Conductimetric

Amperometric

Potentiometric

Calorimetric biosensors

It is appropriate to use biosensors for pollution control or when one moves their eye. The biosensors control the movement in which the eye makes from one's nerves.
