Battery-independent fluorescent nanosensor for non-invasive bioimaging of glucose levels

Monitoring glucose levels is one of the key elements in health monitoring. A research team has now developed a battery-independent fluorescent nanosensor based on single-wall carbon nanotubes and an inactive form of the enzyme glucose oxidase (GOx). Because the enzyme is not in its active form, the analyte is not consumed during the measurement, and continuous, reversible, and non-invasive bioimaging of glucose levels in body fluids and tissues is possible, the team reports in the journal Angewandte Chemie.

Blood glucose levels are typically measured using GOx-based…
