Biosensor companies | Biosensor manufacturers

This page mentions list of biosensor companies. It provides manufacturers or companies which manufacture Biosensors of different types. It mentions selection parameters to be considered for purchasing biosensors for desired application.

What is Biosensor?

The analytical device which detects analyte and combines it with physico-chemical detector or transducer is known as Biosensor. Biosensor consits of bio-receptor, transducer and electronics circuit with display unit.

Bioreceptor is a bio-molecule which recognizes target analyte. The transducer element converts recognition event into measurable signal such as electrical signal. This electrical signal is amplified and processed to display in appropriate measurement unit or format.

The two components viz. bioreceptor and transducer are integrated on single sensor. The biosensor diagram depicts components typically available in a biosensor. For example, glucose measurement can easily be done by simply dipping specially designed biosensor into the sample. Biosensors are simple in construction and quick in measurements. There are different types of biosensors based on their working principles viz. Piezoelectric sensor, Electrochemical sensor, Optical sensor etc.

Biosensor selection parameters

Following specifications or parameters are considered in selecting biosensor for use.
• Sensitivity : It is the measure of response of biosensor to per unit change in analyte concentration.
• Selectivity : It is the ability of the biosensor to respond only to desired target analyte and ignore other interfering chemicals.
• Range : It is the concentration range over which biosensor sensitivity is good. It is also known as dynamic range or linearity.
• Response time : It is the time required to indicate 63 % of its final response due to step change in analyte concentration.
• Reproducibility : It is the accuracy with which biosensor output can be achieved.
• Detection time : It is the lowest concentration of analyte to which measurable response is available from biosensor.
• Stability : This parameter characterizes change in its sensitivity (or baseline) over constant period of time.
• Life time : It is the time period over which biosensor can be used without any performance degradation.

The biosensor companies consider many factors in the development of biosensors. It involves selection of suitable bioreceptor, immobilization method, design of transducer and packaging. The manufacturers finalize various specifications of biosensor such as measurement range, linearity, sensitivity, selectivity etc. as mentioned above.
