I'm a fan of nanotechnology, its a fascinating field with long reaching applications. I found this article mentioning that researchers at the Wyss Institute for Bio bioengineering have developed something quite interesting. Its a robot, a really small one. This nanorobot is made from DNA, and is modeled after the body's own immune system. Its function is to seek out specific cell targets within a mixture of different cell types. It then goes about delivering important instructions to the cells, like telling a cancer cell to self destruct for example.
Since the nanorobot is inspired by the body's immune system it will not be targeted for destruction by white blood cells. Also with this "instruction" ability of it's it can be huge for treating disease. The nanorobots can be considered extensions of the body's own natural immune system. The technology has already been tested on leukemia and lymphoma cells with each being successful in activating the cells "suicide switch". This technology might get rid of the practice of radiation treatment and chemo for cancer patients. Very cool.
