How Biosensors Detect Molecules

Biosensors detect biological molecules and chemical contaminants by combining biology with physical measurement. They can identify targets such as proteins or cells, as well as non-biological molecules like chemicals or contaminants. This makes biosensing a useful field for studying and monitoring many kinds of samples.

Biosensors have revolutionized the fields of medicine and biotechnology through the detection and characterization of target molecules in complex biological fluids. A biosensor is a device that uses a biological receptor molecule, such as an enzyme, to detect a specific compound. Biosensors use different methods, such as electrochemistry, mechan...
