Abstract

The essence of nanotechnology is the ability to work at the molecular level, atom by atom, to create large structures with fundamentally new properties. Nanostructures offer a new paradigm for materials manufacture by submicron-scale self-organization and self-assembly to create entities from the “bottom up” rather than the “top down” method. Nanometer structures will foster a revolution not only in information technology hardware but also in advances healthcare, therapeutics, diagnostics, environment and energy.
