Ten cent origami test for Malaria and HIV
First, test chemicals are selectively embedded on "oPAD" paper. Then, Origami folding wraps up a dab of stuff from the patient. Folded properly, the different reagents line up and become active when you squeeze the oPAD. Unfold and look for a colour change! Doctoral student, Hong Liu at Austin University made the connection between origami which he grew up with and a scientific paper on "microfluidic paper sensors". Next up is a urine glucose test which requires some electricity. A bit of aluminum foil is embedded in folding test paper and it turns into a battery when a spot of pee is added. This has potential to travel cheaply to all corners of the earth where the test will be affordable and can be conducted with volunteers.
