Nanobowls serve up chemotherapy drugs to cancer cells

For decades, scientists have explored the use of liposomes—hollow spheres made of lipid bilayers—to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination, reducing the dose received by the tumor and causing side effects in healthy tissues. Now, researchers report in ACS' Nano Letters a way to stabilize liposomes by embedding a stiff nanobowl in their inner cavity.
