Nanomaterials describe, in principle, chemical substances or materials of which a single unit is sized (in at least one dimension) between 1 and 100 nm (the usual definition of nanoscale [1]). Nanomaterials research takes a materials science -based approach to nanotechnology , leveraging advances in materials metrology and synthesis which have ...
These are nanomaterials in which one of the three physical dimensions in a single unit of the material is on a length scale greater than the nanoscale. Other examples of one-dimensional nanomaterials are nanowires , nanobelts, nanotubes , and nanosheets .
A nanostructure is a structure of intermediate size between microscopic and molecular structures.Nanostructural detail is microstructure at nanoscale.. In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.
Dimensionality plays a major role in determining the characteristic of nanomaterials including physical, chemical, and biological characteristics. With the decrease in dimensionality, an increase in surface-to-volume ratio is observed. This indicates that smaller dimensional nanomaterials have higher surface area compared to 3D nanomaterials.

Nanocomposite is a multiphase solid material where one of the phases has one, two or three dimensions of less than 100 nanometers (nm) or structures having nano-scale repeat distances between the different phases that make up the material.
The improved photostability of quantum dots, for example, allows the acquisition of many consecutive focal-plane images that can be reconstructed into a high-resolution three-dimensional image. [78] Another application that takes advantage of the extraordinary photostability of quantum dot probes is the real-time tracking of molecules and cells ...
Materials, which atoms and molecules form constituents in the nanoscale (i.e., they form nanostructures) are called nanomaterials. Nanomaterials are the subject of intense research in the materials science community due to the unique properties that they exhibit. Nanostructure deals with objects and structures that are in the 1 – 100 nm range ...
