1.1Introduction:

Nanotechnology is the study
of extremely tiny objects. Nanotechnology is the study of manipulating matter
on an atomic scale. The literal meaning of “Nanotechnology” is any technology
which deals in Nano-scale and that has applications in real world. With the
passage of time nanotechnology is evolving day by day. Nanotechnology was
discovered in the mid of twenty century by Professor Dr. Richard P. Feynman.

1.2.1
Nanomaterials:

We categories nanomaterial as
those which have structured components with at least one dimension is less than
100nm. Nanomaterial brings promising advancement to science and technology. we
can be imagine the size of nanometer  as
the diameter of healthy human hair is 10,000 times greater than 1nm. There are
basic fundamental of nanomaterial on the basis of which Nano materials are
classified.

0 Dimension Nanomaterials

1 Dimension Nanomaterials

2 Dimension Nanomaterials

3 Dimension Nanomaterials

1.2.2
(0 Dimension Nanomaterials):

Zero dimensional
Nanomaterials are those in which all dimensions are with in Nano meter length
scale (1nm-100nm) this include quantum dots and cluster of few
Nanoparticles.The most common representation of 0-D Nanomaterial are
Nanoparticles.

There are few properties of
Nanoparticles.

1: Nanoparticles can be
amorphous or crystalline.

2: Nanoparticles can be
single crystalline or polycrystalline.

3: Nanoparticles can be
composed  of single or multi-chemical
elements.

4: Nanoparticles exhibit
various shapes and forms.

5: Nanoparticles can be
polymeric ,ceramic or metallic.

1.2.3(1
Dimensions Nanomaterials):

One dimensional Nanomaterials
are those in which one dimension is out of Nano meter length scale (1nm-100nm)
which includes Nanowires, Nanorods, Nanotubes.

There are few properties of
1-D Nanomaterials.

1: 1-D Nanomaterials can be
amorphous or crystalline.

2: 1-D Nanomaterials can be
single or polycrystalline.

3:  1-D Nanomaterials can be chemically pure or
impure.

4: 1-D Nanomaterials  can be polymeric ,ceramic or metallic.

5: 1-D Nanomaterials are Independent
materials or inserted in inside another 

     medium.

1.2.4(2
Dimension Nanomaterials):

Two dimensional nanomaterials
 are those in which two dimensions are
out of Nano meter length scale (1nm-100nm) which includes Nanofilms  , Nanolayers and Nanocoatings.

There are few properties of
2-D Nanomaterials.

1: 2-D Nanomaterials can be
amorphous or crystalline.

 2: 2-D Nanomaterials can be made up of various
chemical components.

3: 2-D Nanomaterials can be
deposited on substrate.

4: 2-D Nanomaterials can be
used as single layer or multilayer structure.

5: 2-D Nanomaterials can be
polymeric ,ceramic or metallic.

1.2.4(3
Dimension Nanomaterials):

Three dimensional
Nanomaterials are those in which all three dimensions are out of Nano meter
scale (1nm-100nm) which includes Bulk Nanomaterials.Bulk Nanomaterials are
materials that are not restricted to the Nanoscale in any measurement.
These materials are in this way described by
having three subjectively measurements over 100 nm. Materials
have a Nanocrystalline structure or include the nearness of highlights at the Nanoscale.
As for the nearness of highlights at the
nanoscale, 3-D nanomaterials can contain scatterings of nanoparticles, packs of
nanowires, and nanotubes and also multinanolayers.

 1.3 Nanoscience and its Applications:

With the passage of time
nanoscience is emerging day by day. Nanoscience is making an important impact
on human daily life. The assembly of new material at Nano scale length has been
making its impact at large scale in technologies and accessories. By the
evolution of these materials at Nano scale length these materials are showing
extreme properties and maximum efficiency. These Nanomaterials are fabricated
by different techniques at accurate scale and have possible application in many
fields. For example the thin films which are deposited with nanoparticles
are  used in solar cell and in  coating of different type of materials.Nano
membrane are playing vital role in optical field. Nanoparticle are
increasingly  used in catalysis for
boosting up chemical reactions.one of the application of single walled Carbon
nanotubes is that they are used in solar panels due to there strong ultra
violet/vis_NIR absorption chracteristics. Nano-bioengineering
of catalysts is planning to empower change of cellulose from wood chips, corn
stalks, unfertilized perpetual grasses, and so on., into ethanol for fuel.
Cellulosic nanomaterials have exhibited potential applications in a wide
cluster of modern divisions, including gadgets, development, bundling,
sustenance, vitality, medicinal services, car, and guard. Cellulosic
nanomaterials are anticipated to be more affordable than numerous different
nanomaterials and, among different qualities. Carbon nanofibers are  used to make Lithium-ion batteries electrodes
that shows four times more efficient 
storage capacity is relative to current Lithium-ion batteries. In
medical field researchers used nano fibers to capture single cancer cells
circling in circulatory system, and researchers also used nanofibers to deliver
therapeutic drugs. Nano silver
is a disinfectant and harmful to a wide range microscopic organisms like
bacteria, fungi etc. Along the development in nanotechnology our daily will be
much fascinating and by the implementation of all these variations we will be
able to make our present smart as well as future bright.
