Nano-particles are between 1 and 100 nanometers in size. In Nano-technology, a particle is defined as a tiny object that behaves as a whole unit with respect to its transport and properties. Particles are further classified according to diameter and fine particles are sized between 100 and 2,500 nanometers, and coarse particles cover a range between 2,500 and 10,000 nanometers. Molecular Nano-technology is a technology ability to create structures, atomic specifications by mechanosynthesis. This is distinct from nanoscale-materials.
