A biosensor is an analytical device that combines biological detecting elements like a sensor system and a transducer to convert a biological response into an electrical signal. It works by communicating with the analyte being tested and converting the response into an electrical signal by the transducer. Medical biosensors play a significant role in medical diagnostics and patient monitoring, as they are uniquely suited to real-time detection challenges due to their use of biological molecules, tissues, and organisms. Glucose biosensors are widely used in clinical applications for diabetes diagnosis, accounting for 85% of the world market. The biosensor field has expanded into various types, including immunosensors and thermal biosensors.
