Rensselaer: Nanoscale 'Liquid Pistons' Could Drive Lenses, Drug Delivery
Description Researchers at Rensselaer Polytechnic Institute have developed what they call "liquid pistons," in which oscillating droplets of ferrofluid precisely displace a surrounding liquid. The pulsating motion of the ferrofluid droplets, which are saturated with metal nanoparticles, can be used to pump small volumes of liquid which one day could precisely drive mobile phone cameras, medical imaging equipment, implantable drug delivery devices, and implantable eye lenses. The study also demonstrated how droplets can function as liquid lenses that constantly move, bringing objects into and out of focus.

The work was published in the peer-reviewed journal, Lab on a Chip, and funded by the U.S. Defense Advanced Research Projects Agency (DARPA).
