nanotechnology - Bottom-up approach | Britannica

nanotechnology - nanotechnology - Bottom-up approach: Bottom-up, or self-assembly, approaches to nanofabrication use chemical or physical forces operating at the nanoscale to assemble basic units into larger structures. As component size decreases in nanofabrication, bottom-up approaches provide an increasingly important complement to top-down techniques.
