Drug Delivery

Light drives injection

By coupling a bacterial injection system with a light-controlled molecular switch, scientists are able to inject proteins into eukaryontic cells

Nanobowls serve up chemotherapy drugs to cancer cells

Scientists have explored the use of liposomes to deliver chemotherapy drugs to tumor cells. But drugs can sometimes leak out of liposomes before they reach their destination. Now, researchers report a way to stabilize liposomes by embedding a stiff nanobowl in their inner cavity

Cockle shells picked to treat dog cancer

A team explains how nanoparticles made from the cockleshell material calcium carbonate aragonite can be used to carry the anticancer drug doxorubicin. These drug-loaded nanoparticles have been used to successfully treat dogs with solid tumours
