Biosensor is an analytical device containing an immobilized biological material, which can specifically interact with the analyte to produce a signal that can be measured.The biological material can enzyme, antibody, hormone, etc.
A biosensor has 2 components:
- Biological Component: Enzyme, Hormone, Antibody, etc.
- Physical Component: Transducer, Amplifier
Types of Biosensors:
- Electrochemical Biosensors
- Thermometric Biosensors
- Optical Biosensors
- Piezoelectric Biosensors
- Immunobiosensors
- Whole Cell Biosensors
