**8. Applications of biosensors**

Biosensors aid in managing human health by detecting bacteria, viruses, and other pathogens, preventing diseases, rehabilitating patients, and monitoring their wellbeing. People may create and enhance healthy behaviors by using step and activity trackers. For those working in clinical science, these tools provide new avenues. Without extracting blood, these sensors pick up substances. Biosensors have several uses in the medical sciences [14, 66–83].
