Research: Carbon Nanotubes Can Act as Implanted Sensors Long-Term

Carbon nanotubes can act as sensors for up to a year when implanted under the skin or injected into the bloodstream for short-term monitoring, according to new research published at Nature Nanotechnology.

The sensors take advantage of carbon nanotubes’ natural fluorescence, which brightens or dims when coupled to a molecule that binds to a specific target. For this study, researchers from the Massachusetts Institute of Technology focused on nitric oxide which is produced during inflammation and has a role in cancer that’s not well understood.
