Harvard University professor George Whitesides, is combining advanced microfluidics with paper, resulting in a versatile, disposable test that can check any tiny amount of urine or blood for evidence of infections diseases or chronic conditions. This would be a great tool for poor parts of the world because its cheap and easy to use. These devices a paper squares about the size of stamps. The edge of the square can be dipped in urine or placed on top of blood. The liquid then moves through different channels into testing wells. Different chemical reactions happen in the wells, changing the paper either blue, red, yellow, or green. The is a reference key that helps determine the results. Paper based diagnostics already exist for pregnancy tests. The difference here is that Whitesides' devices can perform many reactions.
