Tiny hitchhikers attack cancer cells: Gold nanostars first to deliver drug directly to cancer cell nucleus

Nanotechnology offers powerful new possibilities for targeted cancer therapies, but the design challenges are many. Scientists have now developed a nanoparticle that can deliver a drug directly to a cancer cell's nucleus. They have also directly imaged nanoscale dimensions showing how nanoparticles interact with the nucleus, which dramatically changes shape. The researchers found this shape change linked to cells dying and the cell population becoming less viable.
