Biosensors are widely used to manage disease or track food allergens. They make use of enzymes that specifically detect a substance in a sample and convert it into a measurable signal. DirectSens has over ten years experience with a specific class of enzymes, which is capable of direct electron transfer. This feature enables a 3rd generation sensing mechanism, which is independent of mediators or oxygen, thus simplifies the architecture and increases performance. Sensors based on this enzyme technology are highly accurate, precise and robust.
