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.
