Well, to me it seems they would be related. When you talk about nano particles, it is going to involve a WHOLE LOT of particles. This will demand that they be able to "talk" and communicate with each other to coordinate themselves.
If for example, you inject nano particles into your blood stream (for whatever purpose), they will have to "flow" together. This will have to involve certain amount of intelligence for them to be able to overcome whatever obstacles they encounter. I suppose you could communicate with them through wireless signals to control them, but they will themselves have to have base knowledge and AI to reach whatever goal they have been programed to reach.
