What is a biosensor designed to do?

A biosensor is an analytical device that converts a biological response into an electrical signal, enabling the detection of specific substances, such as chemicals or pathogens. This functionality is vital in various fields, including medical diagnostics, environmental monitoring, and food safety. Biosensors use biological elements, such as enzymes, antibodies, or even whole cells, to recognize the target analyte, which is then quantified or qualified through a transducer element.

The ability to detect the presence of chemicals or pathogens makes biosensors particularly valuable for identifying contaminants or diagnosing diseases accurately and quickly. This direct detection method is crucial for timely intervention in health and safety concerns, showcasing the practical and innovative application of biotechnology in everyday life.
