prototype device
A prototype device takes a nasal swab and, in minutes, shows a readout for pathogen DNA or RNA ton paper strips. The device performs multiple steps like breaking open cells, extracting nucleic acids and copying the strands for detection. It can be heated electrically or via hand-warmer chemistry.

...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.
