Nano technology


Basically, all the things around us compose atoms and molecules. For a deep understanding of the behaviour a particular material, the quantum characteristics of the atoms are observed. Nanotechnology refers to the science of construction of items from bottom-up using the tools and technology available today. It helps in the formation of high-performance products.

With the advent of research, it has found that there exists a scale that is way smaller than the actual molecular scale. It is the nanoscale that can measure even one-billionth of a meter, yes it’s true. 

The nanoscale can arrange these atoms together to form new materials and structures. Nanotechnology is a combination of all the research and inventions involving the properties of elements at this nanoscale.

The term nano targets to the scale of one-billionth of a meter. This is smaller than the wavelength of the light even. Nanotechnology is the research which involves the manipulation of matter at the nanoscale level. 

It was discovered that the quantum properties of matter at the nano scale gets differ than those of the atomic scale. That’s why the research associated with nanotechnology is very broad. It includes many fields of science covering Organic chemistry, Molecular biology, Surface science, Molecular engineering, Semiconductor physics and Energy storage.

Research in the field of nanotechnology

Nanoscale research of matter is too much fascinating as it is the basic stage where the atoms get an arrangement together. Therefore, one can form many different types of materials by manipulating matter at this scale. 

The range of nanoscale is from 1 to 100 nm. Nanometre digit is smaller than the microscale and larger than the atomic scale.

The research around this technology has various properties of the matter, so it is important to have a strong background in multiple sciences.

At the nanoscale level, the rules of the quantum mechanics of the material differ so a lot from its atomic level. Like, a material which behaves as an insulator at molecular form can behave as a semiconductor, when it gets breakdown into the nanoscale. During this level, the melting point of the substances can also change due to an increase in the surface area. 

All the research around nanotechnology in recent days involves the study of these properties at the nanoscale level. This research also helps to know how to use them for new applications and for innovative research.

Nanoscale materials are useful for lots of bulk applications. For instance, nanofillers are useful in solar cells to reduce their production cost. Most importantly, nanotechnology has made a great contribution to the biomedical field.

In addition, applications like tissue engineering, drug delivery, and biosensors have been evolved. It leads to research and innovation of genetics and DNA technology.

Nanotechnology has helped in the structuring of artificial DNA. (Dioxiribo Nucleic Acid) It helps to study some other nucleic acids.

Other above all, in the synthesis of materials, nanotechnology has helped to design well-shaped molecules. New fabrication techniques such as nanolithography, Atomic Layer deposition are available in the market.

What are the types of Nanotechnology?

Nanotechnology deals with the particular study of matter at the nanoscale and the sciences at this scale come under nanotechnology. The one science which deals with the manipulation of matter to form high-performance transistors and microprocessors is Nanoengineering.

Likewise, nanotechnology is useful for the production of pharmaceutical products, it is a Nano medicine. Nanotechnology is highly useful for the fabrication purposes of electronic devices, which are Nanoelectronics.

Over the years nanotechnology has developed as Nanomechanics, Nanophotonics and also Nanoionics, which provides a basic scientific foundation for nanotechnology.

What are some advantages and disadvantages of nano technology?

Advantages of Nanotechnology

The development of this field has been beneficial in the evolution of various new sciences. The properties of the materials get manipulated according to our necessity.

Materials made from nanotechnology are more durable, stable, stronger, lighter, more reactive, better electrical conductors.

Disadvantages of Nanotechnology

The disadvantages are exactly similar to the ones which normally occur with the development of new technology. The effect of nanotechnology on environmental conditions is mostly concerned. The impact of this technology on the global economy is also of a big problem.

In conclusion, Future research in the nano-technology field involves the development of nanorobotics and the applications of it in medicines. New nanomanufacturing devices are useful for future commercial usage.

Moreover, nanomachines have been proposed which will be helpful in the development of new nanomaterials and nanosystems. Matter whose properties can be easily reversible and externally controlled are developed using nano-technology.
