Biosensor Applications, Uses, Examples and Advantages

A biosensor is a device that can convert a biological signal into an electrical or electronic signal. In this article, you will find a lot of uses of biosensors and important biosensor applications. Here you also find the advantages of biosensors.

The biosensors are also identified as Analytical devices. The term 'Biosensor' implies that it integrates biological elements (e.g. enzymes, antibodies, tissue, etc) with a physicochemical detector. When the biosensor comes into contact with the substance it's looking for (e.g., glucose in our blood), a chemical reaction happens. This reaction changes the properties of the sensing element, kind of like how a key fits into a lock and turns it.

The detector or transducer used in biosensors works in a physicochemical way that may be optical or piezoelectric or electrochemical and it transforms the signal resulting from the interaction between the analyte and biological element into an electrical signal or another signal that can be measured easily.

The electrical signal is then sent to a simple display or a device that shows the results. It could be a number on a screen or a light that turns on, indicating the level of the substance detected.

Biosensor Applications and Uses

1. There is a huge application of biosensors in the medical industry for testing purposes.

2. The biosensor is used for pathogens detection purposes.

3. Biosensors are also used for water treatment purposes.

4. Biosensors are used for environmental monitoring purposes such as gas detection or tracing.

5. They are used for toxic metabolite detection.

6. The biosensor is used to identify the contaminants in water such as heavy metal ions. This process is generally used when river water is treated for drinking.

7. Biosensors are used in the security system and biodefense technology.

8. Blood Glucose biosensor is used for glucose monitoring inside the human body.

9. The biosensor is also used for testing of cholesterol.

10. Biosensors are used for the measurement of vitamins, biotin, folic acid, etc.

11. Biosensors are used in Agriculture, Biotech industries to continuously monitor types of chemicals, and their properties in a specific system.

Biosensor Advantages

1. Using biosensors we can easily detect the harmful chemicals or biological agents inside a human body.

2. A biosensor can convert the biological signal into an electrical or electronic signal which can be easily measured, quantified, and amplified.

3. A biosensor can work just by utilizing a specific biochemical reaction, there is no more complexity in the working of the biosensor.

4. Biosensor technology is not so costly, day by day the use of biosensor technology increases.

5. Biosensors are highly specific for the analyte.

6. Biosensor devices are very smaller in size and they are biocompatible.

7. Biosensors are very reliable.

Biosensor Examples

One of the most common examples of biosensors is the blood glucose biosensor which is used to measure the glucose in the blood.
