Long-term sensors, smart thermometers and the Scanadu Nirvana
The first study of long term use of carbon nanotubes as implanted sensors has been published in Nature Nanotechnology. The nanotubes were implanted for a year in animals to track nitrous oxide (NO), an indicator of inflammation which is important in and of itself, but the level of NO is also not understood long term in cancer. To detect NO, the tubes are wrapped in DNA with a particular sequence and wrapped in an alginate gel to stay in place for a recorded 400 days. The MIT team working on this is also working on nanotubes for real-time detection of glucose levels, towards an accurate insulin pump that would end the diabetic’s perpetual Battle of Stalingrad.
