nanoflowers seeded from nano-sized particles of metals that grow, or self assemble, in a natural process. Eye surgeons would implant these fractal devices within the eyes of blind patients, providing interface circuitry that would collect light captured by the retina and guide it with almost 100 percent efficiency to neurons for relay to the optic nerve to process vision. microscopic-beauty
