Bottom up Synthesis of Nanomaterials

Synthesis of nanoparticles is a combination of two stage process, nucleation and growth. Most phase transformations begin with the formation of numerous small particles (clusters) of the new phase that increase in size until the transformation is complete. • Nucleation is the process whereby nuclei (seeds) act as templates for crystal growth.
