Anti-cancer system bursts nanoballoons with lasers

The image shows a nanoballoon before (left) and after (right) being hit by a red laser. The laser causes the balloon to pop open and release the anti-cancer drugs directly at a tumor. Image: Jonathan Lovell.

New drug delivery method targets cancer cells – not the entire body – and limits chemotherapy side effects.

Understanding staph’s relationship with nanostructures

This scanning electron microscopy image reveals how Staphylococcus Aureus cells physically interact with a nanostructure. A bacterial cell (blue) is embedded inside the hollow nanopillar's hole and several cells cling to the nanopillar's curved walls. Image: Mofrad lab and the Nanomechanics Research Institute.

Berkeley Lab-led research could guide the development of bacteria-resistant materials.
