Google X laboratories has been working on a wristband that can detect cancer cells and warn of impending heart attacks and other diseases transmitted through a person’s blood.

Scientists have created synthetic human skin to detect cancer diseases before they develop. The project is still in its infancy, said Andrew Conrad, head of Google Life Sciences.

He explained that the principle of the work of the nanoparticles, which are thousand times smaller than blood cells, is that they attract the proteins and cells of our body, like a magnet.
