...microfluidic chip , which are then filled with tiny amounts of dyed liquid. And by tiny, I mean tiny. Microfluidic chips are used in the lab for certain applications of a minuscule nature, from analyzing single cells to even isolating DNA from single cells. These particular grooves are only 20 microns in width J Tanner Nevil at UC Berkeley...

...microfluidic devices, potentially allowing to make cheap disposable diagnostic tests. A pinprick of blood or drop of urine soaked up at the edge of the Whitesides device moves naturally through the paper, in much the way that wine will spread through a paper napkin. But the paper is treated with a hydrophobic polymer, which directs the liquid...
