George Whitesides' presentation focuses on how, in a world dominated by money, it is possible to mass-produce some kind of method for testing for disease in poor areas of the world without sending a doctor or have a laboratory. Well his solution was a small urine test, about the size of a postage stamp. These tests are small, lightweight, made of paper and tape, and cost almost nothing to produce. The paper absorbs body fluids, such as urine, and changes color to provide diagnostic information, such as showing how much glucose or protein is present. His goal is to deploy these simple paper-based diagnostic systems in developing countries, where people with basic training can administer tests and send results to distant doctors with a cellphone.

Harvard chemistry professor George Whitesides has co-authored more than 950 scientific papers, and is also the co-founder of a dozen companies and holds more than 50 named patents. He works in four main areas: biochemistry, materials science, catalysis and physical organic chemistry. Meanwhile, he is trying to invent a future in which medical diagnoses can be made by anyone at virtually no cost. He co-founded a non-profit organization called Diagnostics for All, which aims to provide low-cost diagnostic devices, to provide healthcare in a world where cost is everything. (http://www.ted.com/speakers/george_whitesides.html) From experience, in his long career in chemistry, George Whitesides was a pioneer in nanoscale microfabrication and self-assembly. Now it's trying to create and mass-produce a diagnostic lab on a chip. While other people are… halfway there… because it's more expensive or requires more steps. This is often true, but when it comes to consumers they often only want what they pay for and not what they don't need. These new tests contain no electronic parts, screens or even words. All they have is the bare minimum of parts and materials used to do exactly what they are intended to do: save lives. Plus, simplicity doesn't pay the people who help it. With such low production costs and the ability to distribute them for free to people who have no money, it becomes a non-profit organization that receives funding, but no one receives a salary. Unfortunately, many people would never dedicate their work to something they wouldn't get paid for, but most people can't quit their old job to work somewhere new. So, this all boils down to being a volunteer organization that I hope becomes a world-changing organization.
