AUSTIN, Texas — Inspired by the paper-folding art of origami, chemists at The University of Texas at Austin have developed a 3-D paper sensor that may be able to test for diseases such as malaria and HIV for less than 10 cents a pop.
Such low-cost, "point-of-care" sensors could be incredibly useful in the developing world, where the resources often don't exist to pay for lab-based tests, and where, even if the money is available, the infrastructure often doesn't exist to transport biological samples to the lab.
