What are biosensors used for?

Biosensors have a wide range of applications. In the medical field, they are used for monitoring glucose levels in diabetic patients, detecting pathogens in clinical samples, and identifying biomarkers for various diseases. Environmental applications include detecting pollutants in water and air, while food safety biosensors can identify contaminants or spoilage indicators in food products. Additionally, biosensors are used in bioprocessing and industrial applications to monitor fermentation processes and other biochemical reactions.
