Nanotechnology: Approaches to Nanotechnology - 0 views

Puja Bhatia on 25 May 13Bottom-up, or self-assembly, approaches to nano-fabrication use chemical or physical forces operating at the nano-scale to assemble basic units into larger structures. As component size decreases in nano-fabrication, bottom-up approaches provide an increasingly important complement to top-down techniques. Inspiration for bottom-up approaches comes from biological systems, where nature has harnessed chemical forces to create essentially all the structures needed by life.
