What are Nanostructures?
Nanostructures are the structures that material consists of the range 1 to 100 nm. Generally, the electrons are confined to a minimum of one dimension. The structure between the intermediate size of microscopic and molecular structure.

While the other of the dimensions are move-free in all dimensions. Generally, it is generated as the by-product of the reactions in the combustion, and its production across the engineering happens in particular functions.
Classification of Nanostructure:
This is classified into four kinds that depend on their dimensions size:
- Zero-Dimensional
- One-Dimensional
- Two-Dimensional
- Three-Dimensional

| Classification of 0D, 1D, 2D, 3D |
Types of Nanostructure:
Nanostructure has many chemical, physical, optical, mechanical, biological, and magnetic properties. However, there are four types here we discuss:
- Carbon Based Materials
- Metal Based Materials
- Composites
- Dendrimers
1. Carbon Based Materials:
It consists of many carbons, that form hollow spheres, tubes, or ellipsoids. Ellipsoidal and spherical carbon nanomaterials are from as fullerenes, rather cylindrical are known as nanotubes. In this regard, many of the applications involve improved coatings, films, lighter, and stronger materials etc.

2. Metal-Based Materials:
This involves nanogold, quantum dots, metal oxides, and nanosilver like titanium dioxide. The quantum dot is a nearly packed semiconductor crystal that consists of hundreds and thousands of atoms, that have some nanometers to some hundred nanometers. Alternating the size of quantum dots alters their optical properties.
3. Composites:
This is the combination of the nanoparticle with some other of the larger, nanoparticle,, and maybe the bulk type of materials. Nanostructures, like as nanosized clays, that are we add and packaging materials of the auto parts, to increase mechanical, barrier, flame-retardant, and thermal properties.
4. Dendrimers:
From branched units, the nanosized polymers are built from this that are present in the nanomaterials. The dendrimer surface has several chain ends, that has that have particular chemical functions. For catalysis it is useful. This is due to three-dimensional dendrimers having interior cavities that place the other molecules, which is good for drug delivery.

Examples of Nanostructure:
- Quantum Dots
- Nanoscale Materials
- Nanoscale Optics
- Nanoelectronics
- Nanomechanical Systems
1. Quantum Dots:
The quantum mechanical property in the Quantum Dots that are semiconductor nanoparticles. In addition, they are utilized in the quantum dot laser, quantum dot displays, and also in quantum dot photodetectors, etc have all of the applications in electronics and optics.
2. Nanoscale Materials:
Nanostructure enables the generation of novel materials with particular properties. For instance, in exceptional thermal and electrical conductivity, carbon nanotubes are exhibited, creating value in electronics and materials science.
3. Nanoscale Optics:
The survey of optics shows the interaction of nanoscale structures with light. This causes the development of the Nanoscale optical structure or devices that involve waveguides, and plasmonic antennas for utilization in sensing and telecommunications.

4. Nnanoscale Electronics:
Nanostructure is reorganized electronics by the capability of the reduction of electronic components. This enables the development of quick and more energy-efficient electronic equipment or devices.
5. Nanomechanical Systems:
Nanostructure is capable of the generation of nanoscale mechanical systems, like as switches and nanomechanical systems. These types of equipment have applications in specific sensing and measurements.
Properties of the Nanostructure:
Some properties are as:
- Surface energy is high
- Surface atoms have large fractions
- In bulk materials that do not exist to reduce imperfections
- Moreover, it has spatial confinement
Conclusion of Nanostructures:
The Nanostructure is the structure that has a particular surface area, happening in the quantum size that shows the conclusion in the brilliant absorption beneath the VIS and UV regions of the spectrum in the solar. The device of fabrication is useful in the nanostructure.
