Justify the statement ‘Nanotechnology plays by different rules.’

I. The aim of nanotechnology is to design nanostructures and nanoparticles for specific applications.

II. It follows a bottom-up approach and requires special techniques to manufacture nanomaterials.

III. The physical properties of nanostructures are dependent on their size and shape.

IV. The functioning of a nanomaterial is based on the surface area (SA) to volume (V) ratio.

V. Greater the SA/V ratio, greater is the reactivity of such materials. Therefore, the same material shows different physical properties at the nanoscale.

VI. Further, large SA/V ratio; the friction and sticking property of such materials is large.

VII. The laws of quantum mechanics determine the forces among nanomaterials. Thus, Nanotechnology plays by different rules.’
