Sensor Chemistry and Mediators
Introduction
Diabetic test strips use sensor chemistry and mediators to measure blood glucose levels accurately. They rely on enzymes like glucose oxidase or glucose dehydrogenase to break down glucose. Mediators like ferricyanide or osmium transfer electrons, playing a crucial role.
Key Components
- Enzymes convert glucose into gluconic acid or other products.
- Mediators facilitate electron transfer between the enzyme and the electrode.
- Electrodes measure the electrical signal generated by the reaction.
Technology and Innovation
Advances in nanotechnology and material science improve sensor performance. New mediator molecules and enzyme variants enhance accuracy and stability.
Manufacturers and Product Lines
Major manufacturers like Roche, Abbott, and Bayer develop innovative test strips. Their product lines feature wireless connectivity and mobile apps.
