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.

Laboratory staff is also working on creating a portable device to regulate the work of the particles, to gather them and analyze cells which particles attract. The device is supposed to become an individual device regularly checking the health status.

''Nanoparticles circulate around your whole body looking for those cells and we collect them using a magnet and basically ask them what they saw,” Conrad said.

The head of research explained that these nanoparticles with cancer cells will “light up.” In order to catch the light, scientists need to study how it passes through the skin. Thus, Google started making “practice arms” with synthetic skin and real human skin from donors, RT reports.

“When they were casting and making these arms they had to make them from materials that behave like skin, have the same autofluresence and biochemical components of real arms,” Conrad said.
