Is Nanotechnology Totally Useless According to You?

Nanotechnology is the science and art of constructing functional and sometimes powerful devices by manipulating single atoms until they are molecularly sized. In order to achieve some relativity on this, one must be aware that a molecule is measured in nanometers, which is, essentially, one billionth of a meter – an atom is ten times smaller than that.

As a revolutionary concept, nanotechnology covers a wide spectrum that can often be a double edged sword. In the right hands, the extreme capability of nanotechnology can be a positive contributor to medical advancements, environmental cleansing, energy conservation and many other areas that can largely improve human existence on our planet. The down side to nanotechnology is that in the wrong hands it can be a destructive force that may ultimately lead to the annihilation of human existence and even of our planet.

There are varying schools of thought on the benefits versus the threats of nanotechnology pursuits. One outlook is that replicating nanostructures could gobble up the entire planet in about three hours flat while another is that nanotechnology as a science could revolutionize medical treatments for conditions that are presently incurable using standard technology.

Nanotechnology has been credited with many beneficial improvements to existing products like fabrics that totally resist staining, scratch resistant eyewear and sunscreen that can endure greater exposure to the elements for longer periods of time. In addition, creating smaller, more powerful devices via this technology has been a positive contributor to revolutionary advancements in computers, more improved diagnostic medical testing and more efficient means of removing toxicity from areas afflicted with environment contamination. Anyone would have to agree that these advantages are certainly not totally useless attributes of nanotechnology.

Additionally, nanotechnology has been credited with creations from a biodegradable plastic made from waste products produced from fruit growing operations to experimental replacement bone tissue that will not be so easily rejected by the human body after transplant. The advantage of such a product will result in easing human suffering while actually contributing to an extended life span. Anybody wanting to improve on humanity would be hard pressed to declare breakthroughs like this as totally useless.

Despite its propensity to do good, nanotechnology could also lead to the creation of more compact and essentially more dangerous weaponry, which, if it fell into the wrong hands could lead to the development of chemical and biological weapons that are far more deadly, harder to avoid and much easier to conceal than conventional warfare.

Naysayers are quick to point out additional negativities of nanotechnology such as the ability of the military or other covert government organizations to conduct continuous, surreptitious surveillance on each and every citizen. Some go even further by concentrating on the hypothesis that nanotechnology, when used to advance greed and power, could result in total physical and/or psychiatric control of one faction over another.

Will nanotechnology ultimately result in ecophaghy – the consumption of the entire worldwide ecosphere – or will all these doomsday predilections just be totally useless fodder for overactive imaginations?

Nanotechnology Cures Medical Ailments

Single units of a nanometer is one billionth of a meter. Nanotechnology in medicine makes use of nanometer sized chips to store and interprets high density quality information. It shows desired utility in accordance with pre-programmed instructions on target tissues. It is increasingly being applied to coax regulation of functional systems at the molecular level. This micro-miniature technology is increasingly finding its way to cure diseases with out the use of surgery. Most of our ailments are the external manifestations of damage caused at the cellular and molecular levels. Rectification to these damages can not be undertaken by conventional surgical instruments too large and crude for the cellular and molecular level manipulation.

Currently when much research is being carried out in cell biology and genetics at its basic precision and accurate level, the call of the hour is devising of a technology that is able to cater to the structure and functions at this level. The nanotechnology is being engineered to intervene as molecular-machines which are sophisticated and well controlled at the unit level. With the use of this technology the micro-molecules injected in the human body will be able to remove obstructions of any kind, function as sub cellular organelles, and kill cancer cells and much more. Nano engineers in Singapore have engineered a polymerized contact lens which is capable of will releasing small amounts of medicine to treat eye related ailments such as glaucoma.

The mechanism that will function behind nanotechnology at cellular level is by way of designing and erecting a programmable self-replicating manufacturing devise capable of identifying defective cells whilst circulating in the circulating system. These devices which are programmable and controllable can detect cancer cells by sensing differential environment between the normal cells and cancer cells and any other unwanted structures. Nanotechnology will be used to supply oxygen to tissues having minimized blood supply due to any of the blood loss reasons. Scientists at MIT have used an artificially synthesized polymer attached to a specific gene coding for the bacterial toxic. The polymer acts like a suicide bomber and attacks the altered cells and gradually destroys it in the process.
