Nanotechnology – The Pros and Cons

Would you like to make the world a better place? Does the thought of living in a world straight from a sci-fi novel excite you? Could environmental problems, species extinction, disease, poverty and starvation become a thing of the past? It’s possible that nanotechnology will change the world in amazing ways. But will those changes be good or bad? Take a look at the pros and cons of nanotechnology to find your own answer.


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.


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.

Space Technology On Science & Scientists

Impact of Space Technology on Science & Scientists: Space technology has become one of the biggest study and challenge for the modern scientists. Space technology in association with other subject helps forecasting weather- its origin, time and magnitude, remote sensing, satellite television, moon mission, astrological predictions and also helps medical science in great deal. In short we can benefit the following things:

1. Movements & facts on Solar System and more about other stars

2. Forecasting Weather- Tsunami, cyclone can be forecasted.

3. Through Communication Satellites Telephone, TV transmission and sending messages can be fast.

4. To locate hidden things under earth i.e. locating natural resources, lower part of Oceans, Seas and its contents and day to day movements of earth.

5. Helps studying X-rays, ultra-Violet rays and disease cancer.

Modern scientists though have tested the success of space technology in the form of spacecraft, space mission i.e. moon mission, mars mission and many other things but the scientists are still on job for finding many unknown things about universe and like earth any other planet or stars have living being possibility or not.

Scientists are using various space technologies to know more about space and its use to the mankind through continuous research and experimentation. For this development they refer Newton’s Law of motion, Einstein’s theory of relativity and ancient philosopher’s like Aristotle and Galileo.

Space Mission: Though space mission is very old but its success came on October 4th 1957 when ‘Sputnik’ an artificial satellite was sent to space by Russian scientists and in the same year on November they sent another satellite Sputnik 2 with a dog in it. On 12 April 1961 Col Yuri Gagarin a Russian astronaut became the first human being to go around the earth in space in a spacecraft called Vostok. On 16 June 1963 Col Velentina Tereshkova a Russian astronaut became the first woman to went around the earth in space. In between and after that many countries have sent their scientist and astronauts to the space and many things about the space have come out.

Future of Space Technology: There are a lot of things unknown about the universe till today which is to be explored and for this NASA is playing a crucial role in developing technology and collecting information about the universe. The way the spacecrafts are made and its technology being developed in high standard we will come to know much more things what are trying for years. This also will give one day an industry called space tourism.
