What is a Biosensor?

A biosensor is a sensor used to detect and measure biological molecules or microorganisms. It utilizes biological materials such as enzymes, antibodies, or DNA to recognize specific chemical or biological substances, generating electrical or optical signals in response. The biosensor works by detecting the chemical reaction that occurs when the target is identified and converting that signal into a measurable output. This technology is widely used in fields such as medical diagnostics, environmental monitoring, and food safety, helping with health monitoring, disease diagnosis, and pollution detection.

Application of Biosensor

✅ Blood Glucose Measurement
Biosensors are widely used for measuring blood glucose levels in diabetic patients. These sensors allow for real-time monitoring of glucose levels in the blood, enabling patients to easily manage their health.
✅ Environmental Monitoring
Biosensors are also used for environmental monitoring, detecting harmful substances in water and soil. For example, sensors have been developed to detect toxic chemicals and heavy metals in environmental samples.
✅ Food Safety Testing
In the food industry, biosensors are used to detect microorganisms and harmful chemicals in food products. They can quickly identify bacteria or pathogens in food, ensuring food safety.
✅ Early Disease Detection
Biosensors are used in the early detection of diseases like cancer and infections. By detecting specific markers or pathogens, biosensors can help identify diseases before symptoms appear.
