Advantages and Disadvantages of Nanotechnology


While nanotechnology is seen as the way of the future and is a technology that a lot of people think will bring a lot of benefit for all who will be using it, nothing is ever perfect and there will always be pros and cons to everything. The advantages and disadvantages of nanotechnology can be easily enumerated, and here are some of them:


Advantages of Nanotechnology

To enumerate the advantages and disadvantages of nanotechnology, let us first run through the good things this technology brings:

  • Nanotechnology can actually revolutionize a lot of electronic products, procedures, and applications. The areas that benefit from the continued development of nanotechnology when it comes to electronic products include nano transistors, nano diodes, OLED, plasma displays, quantum computers, and many more.
  • Nanotechnology can also benefit the energy sector. The development of more effective energy-producing, energy-absorbing, and energy storage products in smaller and more efficient devices is possible with this technology. Such items like batteries, fuel cells, and solar cells can be built smaller but can be made to be more effective with this technology.
  • Another industry that can benefit from nanotechnology is the manufacturing sector that will need materials like nanotubes, aerogels, nano particles, and other similar items to produce their products with. These materials are often stronger, more durable, and lighter than those that are not produced with the help of nanotechnology.
  • In the medical world, nanotechnology is also seen as a boon since these can help with creating what is called smart drugs. These help cure people faster and without the side effects that other traditional drugs have. You will also find that the research of nanotechnology in medicine is now focusing on areas like tissue regeneration, bone repair, immunity and even cures for such ailments like cancer, diabetes, and other life threatening diseases.

Disadvantages of Nanotechnology

When tackling the advantages and disadvantages of nanotechnology, you will also need to point out what can be seen as the negative side of this technology:

  • Included in the list of disadvantages of this science and its development is the possible loss of jobs in the traditional farming and manufacturing industry.
  • You will also find that the development of nanotechnology can also bring about the crash of certain markets due to the lowering of the value of oil and diamonds due to the possibility of developing alternative sources of energy that are more efficient and won’t require the use of fossil fuels. This can also mean that since people can now develop products at the molecular level, diamonds will also lose its value since it can now be mass produced.
  • Atomic weapons can now be more accessible and made to be more powerful and more destructive. These can also become more accessible with nanotechnology.
  • Since these particles are very small, problems can actually arise from the inhalation of these minute particles, much like the problems a person gets from inhaling minute asbestos particles.
  • Presently, nanotechnology is very expensive and developing it can cost you a lot of money. It is also pretty difficult to manufacture, which is probably why products made with nanotechnology are more expensive.

    I think you need to explain more about nanotechnology. Ex., WHAT IS IT?

    Nanotechnology is the science of manipulating matter on the Nano scale. This enables Nano scientists to, for example, place one atom next to another, and create stronger bonds between elements. This could give the new material better characteristics, but it could also carry bad ones as well.

    We’re talking really tiny stuff: one human hair is 100,000 times the width of one nano.

    Actually, it’s 10,000 times the size of a human hair.

    actually its one billionth of a metre

    Sam :Actually, it’s 10,000 times the size of a human hair.

    “A human hair is approximately 80,000- 100,000 nanometers wide”- National Nanotechnology Initiative

    Therefore, Cindy was correct. Sam, like so many others on the internet, has no idea what he/she is talking about.

    It’s all about the references, dear.

    actually a human hair is about 80,000 nanometers wide.

    P.S. I know this because it was one of the things discussed in my college nanoscience course.
