George Whitesides and the Paper Diagnostic Systems

The presentation by George Whitesides focuses on mass production of ways to test diseases in poor areas of the world without going to doctors and laboratories in a world where money is a major part. His solution is a small urine test that is as big as a stamp. These tests are small and lightweight, made of paper and carpet tape, the cost is almost zero. Paper absorbs bodily fluids such as urine, and paper provides diagnostic information such as indicating the amount of glucose or protein by changing color.

He said, you start with paper. It is very cheap. It is water absorbent. It is easy to color. In order to turn paper into a diagnostic tool, Whitesides processes it with a wax printer. The printer melts the wax onto paper and forms a channel with nano-sized molecules at the edge. These molecules react with substances in body fluids. The white side explained that this fluid "distributes themselves to these different wells or holes and then turns into a color." Please think about pregnancy test. For example, a stamp that turns blue in one corner indicates a diagnosis and a pattern in another color diagnoses another. The cost to create a diagnostic stamp is 10 cents each, and Whitesides wants to make them cheaper. Almost every advanced mobile phone with camera can program images of stamps.

This film is not based on actual countries, people, events, but it may be affected as it may be related to some of these problems. There are two different countries to come to the United States. One is a fictional place, Zamunda Africa, and the other is Queens in New York State, USA.

Researchers including George Whiteheads at Harvard University are likely to use mobile phones to report medical treatment to remote areas around the world or to walk for more than a day to see doctors and nurses . The Whitesides team is to work on a paper that can touch with a drop of blood, then take a picture, analyze it, and send a text message to a clinic where you can make a diagnosis.

"Despite future confusion, we live in one of the greatest historical times, software fills the world, fills every niche market, and exciting opportunities are everywhere I guess. "
