Organization of Nanoscale Particles in Three Dimensions

It can be argued that Nature’s greatest gift to living beings may be the molecules. The chemical bonds ‘connecting’ the atoms in three dimensions define the nature of the molecule. On the other hand, an imagination, prevalent amongst the scientists practicing nanoscale science and technology, is to be able to organize nanoscale particles in one, two and three dimensions in a hierarchical fashion. The organized structures are expected to be endowed with properties that are not available with the constituent units.

We work on the development of principles to systematically organize nanoscale particles using molecules as the ‘bonds’. This is based on chemical reactions in the liquid medium. We focus on the organization of metal nanoparticles, quantum dots and atomic clusters.
