2. Introduction  A biosensor is a device that measures biological or chemical reactions by generating signals proportional to the concentration of an analyte in the reaction.  Biosensors are employed in applications such as disease monitoring, drug discovery, and detection of pollutants, disease causing micro-organisms and markers that are indicators of a disease in bodily fluids.(blood)

3. Definition of sensors  Sensor  A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure.

4. Biosnesors  Biosnesors are analytical tools for the analysis of bio- material samples to gain an understanding of their bio- composition, structure and function by converting a biological response into an electrical signal.

6. PARTS OF BIOSENSORS 1. Analyte 2. Bioreceptor 3. Amplifier 4. Processor 5. Display

7. Types of Biosensors 1. Optical biosensors 2. Thermal Biosensors 3. Nucleic Acid-based Biosensors 4. Conductimetric Biosensors

8. Applications of Biosensors 1. Biosensors for Clinical Diagnostics Glucometer is a medical device for determining the approximate concentration of glucose in the blood. glucoseblood

9. 2. Environmental Monitoring Biosensors with sensing elements for nitrates and phosphates are becoming common for water pollutants.

10. 3. Food Industry Biosensors are used in food industry for food quality control for measurement of amino acids, carbohydrates, alcohols, gases, etc.

11. Advantages of biosensor  Specific in response to analyte  Rapid response  Simple to operate  Require no pretreatment of sample  Ease to use  Economical

12. Conclusions  Biosensors are nowadays ubiquitous in biomedical diagnosis as well as a wide range of other areas such as point-of-care monitoring of treatment and disease progression, environmental monitoring, food control, drug discovery, and biomedical research.
