Enzyme sensors

Enzyme sensors are devices that detect specific substances, called analytes, by using enzymes—biological molecules that catalyze chemical reactions. When the target analyte interacts with the enzyme, it triggers a reaction that produces a measurable signal, such as an electrical change. These sensors are highly selective and sensitive, making them useful for monitoring health (like blood glucose levels), detecting environmental pollutants, or ensuring food safety. Essentially, enzyme sensors work like biological detectors, using natural processes to identify and quantify specific substances accurately and efficiently.
