Nanostructures have so many uses that it's unbelievable. One of the advantages of DNT's approach is that they make structures of various sizes by connecting new generations of particles together. Think of it using Tinkertoys; at the center, there's a ball-shape, which is connected to extensions outward. That layer has ball-shapes of its own, which allow another layer on top of it; making the structure larger without wasting a lot of mass. Each generation makes a larger structure, which translates into specific uses. For instance, a G3 (generation 3) structure may fall through a blood vessel, while a G5 structure would follow the vessel, targeting various points on the body.
