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.

Mattresses and Nanotechnology – The Quest For Nano-Mattress

We all know from sad experience that even if an innerspring mattress seems perfectly fine when you buy it new, however after a while the springs wear out and you’re left with a creaky, uncomfortable, sad excuse for a bed. Nanotechnology is here to save the day.

Many people have never even heard of this cutting-edge science, but it’s quite simple: nanotechnology studies and modifies elements at the particle level, so it can be applied to almost anything you can imagine. And when you apply it to mattresses, you get an extremely pleasant result.

Scientists at the University of Florida and the Rensselaer Polytechnic Institute have developed a mattress built on flexible nano-engineered carbon microtubes. In form and appearance this material will basically resemble foam.

Nanotechnology Dangers

Every new technology is a potential tool for good or evil nanotechnology dangers are also possible. Our responsibility as propagators of each new technology is to be informed about their possibilities and act accordingly.

As we investigate the new realm of nanotechnology, it becomes necessary to realize that this new field offers both miraculous potential and also nightmare effects.

The issue is pressing because economic concerns often win out over health considerations. Nanotechnology is no exception; products that have been submitted to scanty research are already making slow but steady breakthroughs into the marketplace.

Billions of dollars have already been spent on development and advertising. Far less has been spent on investigating the ways in which these nano-products interact with humans and their environment.

What is Nanotechnology Used for Today?

Have you ever caught your self wondering , just what is nanotechnology used for today? Nanotechnology controls matter on an atomic level, modifying its effects to achieve desired results. Its uses are therefore extremely numerous.

Any substance in existence can be broken into molecules and tampered with in order to give it different properties and abilities.


The universality of nanotechnology means that it is being applied to almost every facet of modern life. Miraculous effects can be achieved by engineering nanoparticles; for example, researchers have already developed wool and silk that can clean themselves because their altered particles “eat” stains.

Self-cleaning household products are also being developed. The time is not far distant when you’ll be able to spray a nano-chemical onto the grime in your kitchen and watch it disappear and practically never come back, since many nano-chemicals also prevent grime from accumulating.

Medical robot

Researchers have also developed “nanocomposites,” a cluster of nanoparticles from different elements that can, among other things, solve the pollution problem. The Pacific Northwest National Laboratory, for example, has discovered how to alter silica particles so that they attract and capture toxic particles in water.

Nanotechnology’s sociological effects

Every new scientific breakthrough brings with it an effect on society, so nanotechnology’s sociological effects are unavoidable.

Electricity is one of the most recent examples, heralding the development of both television and computers which have changed the entire neurological function of modern generations.

The first and most natural instinct of society is to turn new technology into marketable products. In this sense, nanotechnology’s sociological effects may be primarily economic.

Most new technology finds its outlet in the marketplace under an array of brand names; the invention of computers was quickly followed by the branding and marketing of Microsoft. Sociological history has taught us that mankind’s number one incentive is monetary, and nanotechnology is already following this pattern.

How is Nanotechnology used in space?

How is nanotechnology used in space? We are currently exploring only a tiny fraction of its space capabilities as we study the development of newer, better space materials.

With materials like these we may be able to find ways of launching into orbit that don’t involve costly rockets (and their costly fuel.) Researchers are particularly excited about the possibilities for a space elevator.

Carbon nanotubes are the perfect choice for such an elevator’s cable, since nanotechnology is able to create carbon-based material that is light in weight yet strong enough to withstand the forces it would face in space.

A space elevator would make all kinds of pioneering efforts possible by dramatically reducing the cost of sending things into orbit.

This becomes painfully obvious when one considers that 95% of a space shuttle’s takeoff weight is entirely devoted to fuel storage.

Despite the amusing and whimsical idea of an elevator that reaches all the way into space, scientists are perfectly serious about this endeavor and have already anticipated such practicalities as how and where the two ends of its cable will be anchored, the Earth end will be affixed to a sea anchor that is similar to a drilling rig, and the space end of the cable will be attached to an asteroid.

The Future of Nanotechnology

The future of nanotechnology is completely uncharted territory. It is almost impossible to predict everything that nanoscience will bring to the world considering that this is such a young science.

There is the possibility that the future of nanotechnology is very bright, that this will be the one science of the future that no other science can live without. There is also a chance that this is the science that will make the world highly uncomfortable with the potential power to transform the world. Read the rest of this entry »

The History of Nanotechnology

The history of nanotechnology is dotted with a certain amount of skepticism. Some people hold firmly that this is a brand new form of scientific evolution that did not develop until the late 1980s or early 1990s.

Others have found evidence that the history of nanotechnology can be traced back to the year 1959.

Either way, as scientific development goes, nanotechnology is still a relatively fresh and new arena of scientific research.

Still other scientists hold the belief that humans have employed practical nanotechnological methods for thousands of years, perhaps even longer.


Nanotechnology is the development of progress, as many like to put it, and progress has included the vulcanization of rubber and the introduction of steel into society. These advancements count in the history of nanotechnology according to many well known scientific experts.

Perhaps it might be safer to acknowledge that the basics of the history of nanotechnology have been implemented for thousands of years or longer, but we as a scientific society did not put a name to it until somewhere in the mid 60s.

In order to accurately document the history of nanotechnology, one could argue that it began when we developed the ability to determine particle size, which is indicated to be around the turn of the 20th century.

It was during this time that particle size became a constant factor in scientific exploration. These measurements were recorded at smaller than 10nm, which in lay terms translates roughly into less than microscopic.

The nanometer came on the scene before the onset of the 1960s. The nanometer, for many, is the beginning of the history of nanotechnology. After all, once it could be measured, it would be considered to be an acceptable frame of reference, right? Almost..

The mid 19 teens produced the ability to recognize particles via the use of an ultramicroscope that could detect particles as small as 1/1 millionth of a millimeter. This is a particle smaller than most lay people can not truly visualize accurately. Thus, there are yet even more critics that state the history of nanotechnology actually began in the mid 19 teens when the documented case took place.

Of course, the term itself comes with history. The word assigned to this type of scientific advancement is known to have come from a paper that was released in 1974 written from the Tokyo Science University. There, a student coined the term “nanotechnology” in his paper and the name stuck firmly from then on. This is one area of this science’s history that is not readily disputed, or disputable.

During this time, nanotechnology truly flourished, and as early as 1974 there were numerous break throughs that led scientists to continue to develop this science with fervor. Discoveries such as the famous Finns’ process of atomic layering helped to put nanotechnology on the map when it came to being recognized by the rest of the scientific community.

The idea that one could actually in some sense “touch” atoms and molecules came about in the 1980s, when famous nanotechnological scientists backed up the theory proposed by Dr. K. Eric Drexler, who was responsible for the eventual ability to manipulate atoms and molecules.

This was rather controversial at the time as the mishandling of molecules and atoms were feared should the any scientists with deadly intentions get their hands on the process. The fear was well founded, as molecular manipulation would have certainly been a way to sabotage just about anything, including humane structuring of the natural world.

The 1980s and early 1990s saw a significant increase in the popularity of nanotechnology. This is the science that can figure out how to power our lives with nothing more than molecules and atoms. This is the science where advancements are always happening and being tested.

It won’t be long before we look to nano—scientists to attempt to fix some of the world’s larger social problems with the implementation of technology and progress.
