Normally, fine powders would be called "micronized", but in your case it is sub-micron. I don't think it would be entirely dishonest to call it nano-something, but "nanonized" or "nanoized" don't have a very good ring. I like "nanoparticles", "nanoparticulate", "nanoparticulated". However, they are not neologisms, which would be highly desirable for anything you want to make into a trademark.
