Difference Between Top Down And Bottom Up Approach In Nanotechnology. 1 top down approach refers to slicing or successive cutting of a bulk material to get nano sized particle. Manufacturing process starts from larger structures in top down approach where starting building blocks are smaller than the final design in bottom up approach.
There are two approaches for synthesis of nano materials and the fabrication of nano structures. In the top down approach youwillestimate the duration of deliverables andormajordeliverables. What is top down and bottom up approach in nanotechnology.
Manufacturing process starts from larger structures in top down approach where starting building blocks are smaller than the final design in bottom up approach.
Differences of top down vs. Answer 1 of 2. Top down approaches are backward looking while bottom up approaches are forward looking. 1 top down approach refers to slicing or successive cutting of a bulk material to get nano sized particle.
