In new work recently published in the journal ACS Nano, Kwon's lab developed a stabilized form of a common chemotherapy agent, gemcitabine, and encased it in nanoparticles capable of slowing down their release. In mouse models of human lung cancer, the improved drug inhibited tumor growth more effectively than standard gemcitabine.

"There's been a lot of hype about nanotechnology," says Kwon, who has worked in the field for more than 20 years. "It's an ambitious goal: to target drugs to particular places in our body."
