In remote regions of the world where electricity is hard to come by and scientific instruments are even scarcer, conducting medical tests at a doctor’s office or medical lab is rarely an option. Scientists are now reporting progress toward an inexpensive point-of-care, paper-based device to fill that void with no electronics required. Their study on the extremely sensitive test, which simply relies on the user keeping track of time, appears in the ACS journal Analytical Chemistry. More »
