Glucose Nano-monitor for Diabetics

A new technology is being developed that can constantly monitor a person’s blood sugar level and alert them when they need an insulin shot. Nanosensors, injected under the skin, would trigger a fluorescent response when exposed to an infrared light, and alert a patient if they need insulin.

The nanosensor technology could be used to measure other chemicals, such as sodium, which could be used to detect dehydration.
