Tissue-integrated glucose nanosensor uses inactive glucose oxidase enzyme for continuous monitoring

Researchers at the University of California, Berkeley, have developed a battery-independent fluorescent nanosensor based on single-wall carbon nanotubes and an inactive form of an enzyme called glucose oxidase. This nanosensor enables the continuous, reversible, and non-invasive bioimaging of glucose levels in body fluids and tissues. Also, the use of inactive glucose oxidase molecules has major advantages. For example, the manufacturing process of the nanosensors can be simplified, and no toxic byproducts are created.
