Google developed a cancer detection device

US technology firm Google is developing a device that can detect early signs of cancer, heart failure and many other serious diseases.

>>>Machinery will diagnose cancer for humans

According to the Wall Street Journal, Google said the technology is a combination of disease-detecting nanoparticles introduced into a body with a wrist sensor . While in the blood, nanoparticles are about one-thousandth the width of red blood cells that will cling to cells, proteins and tissues in the human body.

Nanoparticles will detect tiny changes in the biochemical system of the human body, thereby sending early warning signals for cancer, heart failure and many other dangerous diseases to the wrist sensor.

Early detection is a key condition for treating diseases, especially cancer. Modern medicine can only detect cancers like pancreatic cancer when the patient has entered a critical stage.

'All medical tests that patients have to do will be done through this system. That is our goal ' - Dr. Andrew Conrad, Head of Life Sciences team of Google X lab, where this research project is being implemented. Dr. Conrad, a molecular biologist, has developed a cheap HIV test device that is widely used around the world.

He stressed that Google wants to change medicine from 'reacting' and 'treating' to 'active' and 'preventive'. "Nanoparticles provide the ability to explore the human body at the molecular and cellular levels, " Conrad said. Google is designing nanoparticles capable of marking different disease cells.

They can cling to a cancer cell or cancer DNA fragment or find signs of blood chemistry changes predicting a stroke, heart failure or liver failure . BBC quoted Paul Workman as belonging to Cancer Research Institute says this is a great idea.

'If we can detect cancer early and other diseases, we will be able to intervene by therapy or simply change the way the patient works' - Dr. Workman stressed.

Scientists assessing nanotechnology has a great influence on modern medicine. The US government alone has invested more than US $ 20 billion in nanotechnology research activities since 2001, including US $ 4.3 billion for medical projects.

This is another attempt by Google to expand its reach out of traditional technology areas such as searching the Internet. The Google X lab is developing a self-driving car and Project Loon provides Internet services for rural and forested areas with a weather balloon system.
