Nanoscience and Nanotechnology have emerged within the borderland between physics, chemistry and biology. When a material is reduced in size till a nanometric levels, Its properties and behavior are described by quantum physics and chemistry not the classical science. There is not a defined limit between classical and quantum science but as while the material is reducing its size the energy levels, those that say us how the materials behave, are more discrete going from classical to quantum physics and chemistry.

Quantum Science is not so common to us because we are living in a macroscopic world where we can easily understand the trajectory of a ball in a basketball match but not the route of an electron because it is described by probabilities. However the quantum world is now quite present in our modern live because it plays an important role in the way the semiconductors, superconductors, lasers, an now nano-materials work. In the future, we should like to control and organize them into new structures with new abilities.
