The state of Nanostructures will create a new physica, mechanica, and thermal properties of solid material. For example energy gap for Si increases from 1.1eV for its bulk state to 1.6eV for a nanopar size of about 5nm. In this siz scale all other parameters accordingly changes. For example in technological point of view multi optical frequency detector can be made from the same material with only different device thickness layer for the same material

Ns/Nv = 1/2R, where Ns = concentration of surface atoms, Nv = concentration of volume atoms and R = radius in nanometers. As the radius decreases (and for example reaches nanoscale) the proportion of surface atoms increases compared to the number of volume atoms.
As the ratio changes in favour of surface atoms, the properties of the material changes. These new properties could therefore be used to create new devices.
