Types of biosensors, their working principles, and applications in the medical industry

Types of biosensors	Description	Application
a) Resonant biosensor	Acoustic wave transducers are used with receptors	Analysis of therapeutic antibody concentrations
b) Optical detection biosensor	A signal is generated when UV light passes through the silicon wafers	Therapeutic Drug Monitoring
c) Thermal detection biosensor	Temperature detectors are used to monitor changes in temperature	Constantly monitor body temperatures
d) Ion sensitive biosensor	The interaction of ions with a semiconductor changes the electric potential of the semiconductor which is then measured	Drug testing and screening
e) Electrochemical biosensor	It generates ions by a chemical process that changes the electrical properties of the analytic solution	Early detection of gene mutation and cancer
