BIOCATALYSIS BASED BIOSENSORS

Biocatalysy based biosensors are dependent on Enzymes.

Two mechanisms used in the Biocatalysis based biosensors are:

• Mechanism in which the enzyme catalytically transforms the analyte
• Mechanism in which the analyte inhibits the activity of the enzyme.

I think rest can be added to the answer by u. however i will provide a brief outline:

• Definition of a Biosensor
• Components of a biosensor
• Explanation abt the enzyme based biosensors
• Applications with some examples
• Advantages and Disadvantages of Enzyme based Biosensors:

Advantages:

• Specificity
• Fast reaction time and thus a fast response time is observed

Disadvantages:

• Expensive
• Lose activity when the operational conditions are beyond limits (pH, Temp etc)
• Lose activity after few cycles of use
