...Paul Yager, a biochemist at the University of Washington, meanwhile, has developed a handheld plastic device the size of two stacked card decks that contains strips of patterned paper and wells containing reagents and dyes, and into which a user would insert a fluid sample. The patterns of dots that appear after 20 minutes could be read by a clinician or sent via smartphone camera to a physician elsewhere. Yager says that the box could cost as little as $1 to manufacture in bulk.
