Question

list the different properties of nanoparticles which make them from bulk materials.?​

Answer 1

Nanomaterials or the Nanoparticles are the set of particles or the substances where atlas one dimension is less than approximately 100nm.

or it can be also classically illustrated as the follows:

Nanomaterial is an object that has atleast one dimension in the nanometer scale approximately 1-100nm.

Note: Richard Feynman is known as the father of nanotechnology.

Bulk Material

A bulk material exhibits a square root energy (E1/2) dependence of the density of states, while in a 2D system it is described by a step function, the 1D systems show an E−1/2 dependence for each quantized state, and in 0D, all available states exist only at discrete energy values since the electron is confined in all three spatial dimensions [35,36].
