Novel connector uses magnets for leak-free microfluidic devices

Like other users of microfluidic systems, National Institute of Standards and Technology researcher Javier Atencia was faced with an annoying engineering problem: how to simply, reliably and most of all, tightly, connect his tiny devices to the external pumps and reservoirs delivering liquids into the system. While pondering this one day, he randomly picked up two magnets and began playing with them. As the magnets pulled apart and then snapped back together, Atencia realized that he had his solution.
