Google is working on nanoparticle for finding cancer and fake skin for testing communication

Hidden away inside a world-class life sciences lab on Google’s campus, doctors are trying to change the way people think about their health.

Google has been working on magnetic nanoparticles that would seek out cancer cells in the bloodstream and report back to a smart wristband.

Google is using light signals to talk to the wristband through the superficial veins on the underside of the wrist.
