Gold Nanoshell Cancer Therapy (2005)

Anyone know what happened to research on this? It seemed like a reasonable approach to treating some types of cancer like subcutaneous tumors and brain tumors. There's a wikipedia article[1] where the last reference is from 2011 and things were looking good at that point.

IIRC brain tumors can be really tricky to treat and this method showed some promise. The testing on mice was working well back around 2010 and I figured it would be further along by now.

Haha, wrong video sorry!

NOVA used to have a neat video about it so I just linked to the first thing after searching for nanoshells. Here's an article about it at least:
