1st Place, World Citizenship: Team For a Better World, Portugal
Ana Ferraz, the one and only team member of Team For a Better World, made a cheap, portable device that can quickly determine someone's blood type in 5 minutes. It has six containers for blood, into each of which you put a reagent. A small centrifuge in the device mixes it up, causing agglutination in some containers, or not, depending on the blood type. The lid of the device contains LED lights and a camera, which takes a picture of the test results and sends it to the software program on a computer. The software analyzes the photo, and determines the blood type. Ferraz says the system could be used in the future to test for other diseases that would react with agglutination to certain reagents, such as syphilis.
"With this portable prototype that eliminates travels to the laboratory, [you can] earn up time to save lives," Ferraz says.
