Mr. George Whitesides, professor at Harvard University has developed a diagnostic tool which is very easy to use and absolutely cheap to afford. This tool of Prof. George is turning out be very much useful and scientific world consider this invention as a boon to mankind since, the cheap diagnostic tool can prove to be immensely helpful for millions of poor people around the globe. Coupling two technologies-one being the most modern and the other being the oldest ever, the professor defines a solution which is very much practical.
The professor uses the wide opportunities in micro fluidics and the usage of paper to derive at a unique solution. The device has only the size of a postage stamp and is made of paper. The square shaped material obviously has edges, and these edges when dipped into a blood sample will collect it soon and route it to the channels for testing.
