Explain the construction of a mass based biosensor giving suitable analyte and compare the same with optical based biosensor?
Introduction What are biosensors? It is an analytical device that detects changes in Biological processes and converts them into an electrical signal which can be then measured or analyze. The biological material is usually in the form of an enzyme, with the help of a process known as electroenzymatic approach, which is a chemical process of converting the enzymes into corresponding electrical signals (usually current) with the help of a transducer. The combination of biological element and a transducer will convert the biological material into a corresponding electrical signal. Depending on the type of enzyme, the output of the transducer will be either current or voltage. Biosensors are based on the method of the transduction, which is classified into three category:- Mass based biosensors Optical based biosensors Electrochemical biosensors Mass based biosensors The mass based biosensors, also known as gravimetric biosensors apply the basic principle of a response to a change in
