Low Cost Paper Lab Will Check Your Blood

Testing your blood might be a troublesome process, especially if you’re in countries that aren’t that well developed. It seems that Harvard chemist, George Whitesides, might have come up with a simple solution on how to tackle this issue, and it just costs a cent. This little square of paper contains comic book ink, which is water-resistant, and will push the blood dropped on it into different paper channels, each of which contains chemicals that react with the blood, and will change color to indicate if the blood contains a certain type of disease. With a low production cost, and the simplicity of its use, it certainly seems like a viable option. Video after the jump.
