Drug Delivery

Nanobowls serve up chemotherapy drugs to cancer cells

NanobowlsServeUpChemotherapyDrugsToCancerCells
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

Nanostimulators boost stem cells for muscle repair

Researchers demonstrated that “nanostimulators” – nanoparticles seeded with a molecule the body naturally produces to prompt stem cells to heal wounds – can amp up stem cells’ regenerative powers in a targeted limb in mice

Breakthrough in molecular machines

BreakthroughInMolecularMachines
Molecular machines have the potential to revolutionize the future – if we can find a way to control them. Researchers now report that they have found a way to control the small machines so that they move in a certain direction – for example, into the bloodstream

Screw cancer: Microneedle sticks it to cancer tissue
