A biosensor can be used to detect blood glucose level of a person. True or false?

The correct option is A True
Biosensors are the devices with an immobilized biological material such as enzymes, hormones, DNA, antibodies etc. Thus a biological component is combined with a physicochemical detector. They convert the biological signal into electrical signals. They can be used in medical field, agriculture and industries. Few applications include:
1. Blood glucose level can be detected.
2. pollution level of water can be detected.
3. Screening of diseases.
4. Check the fermentation during the production of beer.
