lease of the drugs."

The next step in the research is to design and optimize liposome/nanoparticle assemblies that can target cancer cells or other disease-causing cells. In vitro cancer cell studies are already underway in collaboration with URI pharmacy professor Matthew Stoner.

"We are functionalizing the liposomes by putting in different lipids to help stabilize and target them so they can seek out particular cancer cell types," he said. "We are building liposomes that will attach to particular cells or tumor regions."

Bothun said that research on nanomedicine shows great promise, but there are still many challenges to overcome, and the targeting of appropriate cells may be the greatest challenge.

"Any ability to target the drug is better than a drug that goes everywhere in your system and generates off-target effects," he said, noting that the hair loss and nausea from anti-cancer drugs are the result of the high drug concentrations needed for treatment and the drug's affect on non-target cells. "If you can get an assembly to a targeted site without losing its contents in the process, that's the holy grail."
