Bottom Top Approach

Bottom Top Approach: There are two approaches for synthesis of nano materials and the fabrication of nano structures. Top down approach refers to slicing or successive cutting of a bulk material to get nano sized particle. Bottom up approach refers to the buildup of a material from the bottom: atom by atom, molecule by molecule or cluster by cluster. Both approaches play very important role in modern industry and most likely in nanotechnology as well.
