Nanotechnology on the cellular level, Nano cell retrievers and transporters

[dragon2211]

I have a question to ask. I have know knowledge of nano research. I have been reading about it a lot lately. I was particularly interested in a report that discussed how nano bits were developed that could signal out certain cells, pick them up and transport them to another area. My question is , could these nano bits locate cancer cells, pick them up and send them to some organ in the body that could flush them out of the body. I would like to know if this has ever been looked at or if it is even passable.What a great way to defeat cancer if this could be done.

Im just winging it but it might work. They growth process of cancer cells is fairly

quick so as long as you could beat the regenerative pace of the cells you could \

pick it apart in a way perhaps?
