Abstract
Biosensors are analytical devices that are broadly used for the detection of
chemical substances like tissue, organelles, cell receptors, enzymes, antibodies, etc.
Smart materials respond to the external impulse, and convert the impulse to readable
signals. Nowadays, smart materials are used in every requirement of a human being.
The various kinds of smart materials are the subject of extensive investigation. This
chapter examines the fundamental idea and practical use of smart materials in the
biosensing industry.
