Thoraiya DyerHow nanoparticles kill tumors in the brain

Brain cancer is rare. But other types of cancers are not. Doctors know what drug to use, but they don't know how to target the tumor so the rest of the healthy cells won't be destroyed.
Consider this: The researchers at the University of Michigan (U-M) Comprehensive Cancer Center have found a way to inject the drug Photofrin into nanoparticles, which in turn target the cancerous area -- a not too invasive process that resulted in the survival of brain cancer afflicted lab rats and extended their lifespans way longer than expected.
How does it happen? "Photofrin is drawn through the bloodstream to tumors. Doctors then use a special laser light to activate the drug, which collapses the blood vessels that feed the tumor. Without its blood supply, the tumor starves."
We have seen but the tip of the iceberg!

...Maybe not so demented after all?
My daughter and I have great hopes for advances in the uses of nanobot-technology, as she has Cerebral Palsy. We know one day they'll find a way around the peculiarities that is Cerebral Palsy and be able to re-join the parts of the brain that are destroyed at birth through this type of nano-bot or bio-technology.
Great Post, thanks for the update and links.
