UCLA -- UCLA scientists have succeeded in making unique nanoscale droplets that are much smaller than a human cell and can potentially be used to deliver pharmaceuticals. “What we found that was unexpected was within each oil droplet there was also a water droplet — a double emulsion,” said Timothy Deming, professor and chair of the UCLA Department of Bioengineering and a member of both the California NanoSystems Institute (CNSI) at UCLA and UCLA’s Jonsson Cancer Center. “We have a water droplet inside of an oil droplet, in water.”
