Harvard researchers announce new nanotechnology cancer test.

I imagine similar methods ought to be possible to test for things other than cancer. Can you imagine a day when you can go in to see your family doctor and with one drop of blood and a $5 test kit be checked for everything from cancer to that season's strain of the flu? Throw in other developments such as a group I heard about that was working on an MRI machine that could fit on a tabletop without the need for cryogenic cooling of it's magnet and the future of medicine looks pretty good.
