Nano-Ribbons to Monitor Glucose Level from Body Fluid

An ultra-thin, flexible sensor that could be incorporated into contact lenses or on the back of watches for real-time glucose tracking has been developed by a research team. The team created a biosensor using nanoribbons of indium oxide, an enzyme glucose oxidase, a natural chitosan film and single-walled carbon nanotubes. When glucose is present in a test sample, it interacts with the enzyme, setting off a short chain of reactions and ultimately creating an electrical signal.
