Nanotechnology :- New Revolutionary Technology

 today billions of mobile devices with extraordinary powers are uniting with advancement in robotics, Artificial intelligence & nano-tech In thinking about nanotechnology today, what's most important is understanding where it leads, what nanotechnology will look like after we reach the assembler breakthrough.

Nanotechnology is an idea that most people simply didn't believe. Likewise nanotechnology will, once it gets under way, depend on the tools we have then and our ability to use them, and not on the steps that got us there.

 Nanotechnology is a term used in reference to the science and engineering whereby the basic building blocks of matter such as atoms and molecules are manipulated. In the future, nanotechnology will give a greater control over the materials used in the manufacturing processes. In addition, nanotechnology will also enable manufacturers to have control over how materials are produced. 

Nanotechnology Is a Good Thing and Should Be Embraced

Nanotechnology should be embraced because experts have noted that the technology will have a positive impact on every sector of the economy. For example, nanotechnology will have a significant impact on medicine, reduce energy consumption, and replace the silicon-based technology used in computing and electronics. Experts have noted that research in nanotechnology will have to go on because of its positive impact on the economy. For instance, experts have noted that nanotechnology will  cross USD 12 billion in revenue by 2021 . The benefits of nanotechnology are already being realized. 

Why is Nanotechnology Being Used? 

Nanotechnology is a relatively new form of technology that uses the smallest of particles, in order to enhance everyday items that we use. It is currently making headway in all sorts of different areas, everything from the human body to sports to green energy. Our health is being improved by creating cancer killing nano-robots and anti-bacterial band-aids. Batteries in our phones, laptops, and cars are becoming smaller, along with green energy becoming more efficient. Nanotechnology is becoming cheaper for the everyday person, and is the future of microscopic technology in order to make our everyday lives easier, healthier, and more efficient. 

Where it's been used?

Nanotechnology is effecting everyday people through the use of antibacterial nano-materials. Band-Aids are able to have more of an abundance of anti-bacterial nano-particles on them, allowing them to be more effective in healing wounds. In particular, silver is being used for its anti-bacterial properties, and is working well, because of the increased surface area that nano-particles provide. Along with Band-Aids, Sunscreen is being enhance with aluminum oxide, which absorbs sunlight. When aluminum oxide is put into a nano-solution, it won't degrade when it comes in contact with sunlight, so the anti UV ray properties that aluminum oxide has stays intact. Another use of nanotechnology that is affecting us every day is in our toothpaste. Certain types of toothpaste have nano-particles of calcium and silver in them. These particles help to fill in cracks of your tooth enamel which leads to cavity prevention. 

the Negatives of Nano-Tech

Weapons of War

On the instrumental level, concerns include the possibility of military applications of nanotechnology (for instance, as in implants and other means for soldier enhancement like those being developed at the Institute for Soldier Nanotechnologies at MIT) as well as enhanced surveillance capabilities through nano-sensors. There is also the possibility of nanotechnology being used to develop chemical weapons and because they will be able to develop the chemicals from the atom scale up, critics fear that chemical weapons developed from nano particles will be more dangerous than present chemical weapons.

Fear of the Unknown

Nanotechnology is quite a new concept and some effects are time dependent so it's difficult for experts to predict the damage nano-particles might do. There are concerns about how nano-particles may accumulate in nature. Could large amounts be ingested by fish? And if so, would if be harmful? Would the particles be passed along the food chain like DDT. Thresholds need to be determined. It's vital to find out how to remove or simply detect nano-materials if they become problematic. 

The Project on Emerging Nanotechnologies (PEN), also Washington-based, says it has inventoried more than 600 consumer products in 20 countries with nano-scale materials, and "new nano-tech products are hitting the market at the rate of three to four per week."  The interest in nano-materials is coming at a time of growing awareness of how chemicals – many of which we don't know are manufactured into the products we use on a daily basis – may be causing us harm. 

Robots Taking over the World

Believe it or not there is a very real fear out there of robots controlling the world one day. This is not as far removed as one might think as robots are becoming freakishly independent. Nanotechnology is playing a major role in the creation of these robots. Take a look at the video on the right made in February of this year which has gone viral. The video shows robots which are completely autonomous playing an eerie version of the James Bond theme tune on various instruments:
