 Costing just a cent to produce and requiring just a single drop of blood to function, this paper chip, designed by chemist George Whitesides, can diagnose HIV, tuberculosis, malaria and more. What substance makes this tiny marvel possible? Comic-book ink. The water-resistant ink pushes the blood into the different paper channels, each of which contain chemicals that react with the blood and change color to indicate the presence and severity of the various diseases. |
