Nano technology

Nano Technology plays an important role in advancing technologies and developing innovative technologies. Here, we will learn more about nanotechnology.

Table of Content
  •  

Nanotechnology, also known as nanotech or nanotechnology meaning controlling and understanding the matters like atoms, and molecules, that fall within the dimensions of 1 to 100 nanometers to develop some innovative technologies and applications. It includes some diverse fields of science such as organic chemistry, energy storage, surface science, engineering, molecular biology, microfabrication, molecular physics, and semiconductor physics. As of now, scientists are under debate regarding the applications of nanotechnology. With the help of this technology, new devices and materials can be created, and it has a wide application as well. The major application of nano technology is in nanoelectronics, biomaterials products, and nanomedicine. 

Origin of nanotechnology 

Nanotechnology came into the discussion from Richard Feynman, a famous physicist. This discussion started from the “There’s plenty of room at the Bottom” talk, which is also famous, and in this talk, the possibilities of production from atomic manipulation were described. It was started in 1959, and after a decade, Norio Taniguchi coined the term nanotechnology.

What is nanotechnology?

Nanotechnology means the execution of engineering, technology, and science at a nanoscale that has dimensions between 1 and 100 nanometers. Nanotechnology and nanoscience refer to the application and study of these things under nanoscale and how we can use them in other fields of science. 

Fundamental Concepts of Nanotechnology Engineering 

Nanotechnology engineering and nanoscience include controlling molecules and atoms, which has made everything present on earth. As these atoms and molecules cannot be seen from naked eyes, the microscope used to see nano things was made in the 1980s. It includes all the abilities that lead to producing items using techniques from bottoms up and the tools that are now developed to generate such products with great performance. 

Current research

As of now, a few approaches are being adopted for this technology. These include:

  • Nanomaterials: This involves studying and developing materials that exhibit characteristics that arise via nanoscale dimensions of those materials. 
  • Bottom-up Approach: This consists of the arrangement of components that are smaller into a complicated assembly. 
  • Top-down Approach: This consists of creating smaller devices with the help of larger ones. 
  • Functional Approach: This consists of the development of components for specific functionality. It is developed without giving any regard to the assembly of matter. 

Current examples of nanotechnology

Nanotechnology is now used in some major industries. Some of the current examples of nanotechnology are discussed below.

Nanotechnology in Medicine

Nanotechnology in medicine is now giving us some breakthroughs. With the help of nanotechnology, medicines are now becoming safe, cheap, easy to access, and even personalized. In the medicine industry, nanotechnology has given many positive results, and various studies are going on for the same. One good example includes the development of possibilities for increasing nerve cell growth with the help of nanotechnology. 

Food Security 

In food packaging, nanosensors are now used in detecting contaminants like salmonella. 

Automotive 

There are now rechargeable batteries of high power resulting from nanoengineered materials. 

Electronics 

Nanostructured polymer films are now incorporated in modern screen appliances like phones and iPads.

Energy

Nanotechnology is now also used in energy areas as it has helped improve solar panels’ efficiency. It is also used in creating new types of batteries and has also made solar panels cost-effective. This has also helped enhance fuel production efficiency with the help of catalysis. 

Environment 

Scientists and researchers are now developing nanostructured filters to help remove impurities and viruses from water. This can help increase the availability of drinking water and be affordable. There is also the development of paper towels made by nano fabrics that absorb oil twenty times more than its weight. This can be used in the clean-up of oil spills. 

Cosmetics

Nanomaterials are also used in cosmetics as they improve the absorbing, cleansing and coverage of cosmetic products.

Textiles

Additives of nanoscale are used in fabrics that help make the fabric stain resistant. It can also make it wrinkle-free and reduce and resist bacterial growth. 

Conclusion 

Nanotechnology is all about studying and understanding molecules and atoms, and other nanoscale materials. It also involves controlling and seeing how they can be helpful in different industries. There are currently many successful examples of nanotechnology present in different industries, and it has proved beneficial so far. Scientists are hoping that in the future, nanotechnology will give more applications.

Ans : When nanoparticles enter into an environmental exposure, they can either remain intact, or they can undergo any process which is as follows: 

  • Speciation
  • Biological transformation into chemical transformation 
  • Settling
  • Dissolution
  • Chemical transformation into another type of chemical
  • Agglomeration 
  • Deagglomeration

Ans : Nanomaterials are classified into three types based on their dimensions and shape. These are:

  • Nanoparticles: Their dimensions are in nanoscale and are three dimensional.
  • Nanowires or Nanotubes: Their diameter is in nanoscale. They can be longer than hundreds of nanometers.
  • Nanoplates: Their thickness is in nanoscale. However, their two dimensions are significant, for example, graphene.

Ans : Nanoscience refers to the study of materials and structures that are of nanoscale. It also involves studying their characteristics and how they can be used for different applications. It is a cross-disciplinary study. This means that scientists from different fields study it and use it to understand things around us much better. 

Ans : Nano technology is one of the most emerging fields of science. It is expected to show some great future developments and has rapid growth. It is also predicted that nanotechnology can help increase the economic growth of a country, creating more job opportunities. As per scientists, now we are at the end of the first generation of nanotechnology and entering the second generation. There will also be a total of four generations. We can also see some great examples of nanotechnologies and how it is used in different industries. So, there are very high chances that nanotechnology will have a bright and strong future.
