Google aims to develop cancer diagnosis pill
Google's research arm, Google X, is working to develop technology that can detect cancer, heart attacks and other diseases before physical symptoms even appear.
Researchers led by molecular biologist, Dr Andrew Connor, hope to develop a pill that works in conjunction with a sensor worn on the wrist.
Nano-particles that detect disease will enter the bloodstream when the pill is swallowed while the sensor monitors the blood for early warning signs of disease.
Dr Connor told BBC News: "What we are trying to do is change medicine from reactive and transactional to proactive and preventative.
"Nanoparticles... give you the ability to explore the body at a molecular and cellular level."
