What are nanomaterials?
Nanoscale materials are defined as a set of substances where at least one dimension is less than approximately 100 nanometers. A nanometer is one millionth of a millimeter - approximately 100,000 times smaller than the diameter of a human hair.
Nanomaterials are of interest because at this scale unique optical, magnetic, electrical, and other properties emerge. These emergent properties have the potential for great impacts in electronics, medicine, and other fields.
Why different properties?
Why different properties?
The two main reasons why materials at the nano scale can have different properties are increased relative surface area and new quantum effects.
Nanomaterials have a much greater surface area to volume ratio than their conventional forms, which can lead to greater chemical reactivity and affect their strength.
Also at the nano scale, quantum effects can become much more important in determining the materials properties and characteristics, leading to novel optical, electrical and magnetic behaviours.
Common types of nanomaterials include nanotubes, dendrimers, quantum dots and fullerenes.
Nanomaterials have applications in the field of nano technology, and displays different physical chemical characteristics from normal chemicals (i.e., silver nano, carbon nanotube, fullerene, photocatalyst, carbon nano, silica).

Application:
Nanomaterials split their conventional counterparts because of their superior chemical, physical, and mechanical properties and of their exceptional formability.
Thus, Nanomaterials have wide range of applications in the field of electronics, fuel cells, batteries, agriculture, food industry, and medicines. Some are listed below.
