Nanomaterials Synthesis

Nanomaterials Synthesis: Nanotechnology relates to the ability to build functional devices based on the controlled assembly of nano scale objects for specific technological applications.

Bottom up and Top Down 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.
