Nothing is permanent in life, except change. In terms of technology, it is one hundred percent true. Something new is constantly happening, and one can assume that today's technology is only two or three years old. Where are those huge computers that used to look so bulgy to understand them. Now it is palm tops that will fit in the smallest of the hands! The whole game is about technology!
A new more subtle technologies is emerging, known as nanotechnology! This is a separate branch that is being exposed to the students in many universities.

What is nanotechnology?
What's so significant about a goat's head? ” How subtle is nanotechnology? So even more subtle than your blood cells! To make such a small substance or such a device, to think about how these things can be used in practice is to study nanotechnology and such microscopic objects, to find out what rules they follow is nanoscience. The machine we use today requires many things like iron, cement, wood and other metals. But when making nano-devices or nano-materials, we don't have to deal with these big things, we have to play with their atoms.
The idea behind this is to create the substance or device you want by fine-tuning the right atoms and molecules very delicately. Nano is the original Greek word. It means small or subtle. How small is the smallest? So one nanometer is 1 divided by 1 to 9 zeros (1/1000000000) meters. One hundredth of a meter is a centimeter. Your finger is roughly one centimeter thick. One thousandth of a meter is a millimeter.
Nanotechnology is a combination of physics, chemistry, biotechnology, and biology! For students who have a special interest in all the above sciences, this science or technology should posses a challenging career that drives one’s intellect. If the tip of a needle is one milli meter long, it is considered to be equal to one million nano meters. Also, if the red blood cells in the human body are 2.5 micrometers, then the same number in nano meters is around two and a half thousand.
In short, in nano technology, the concept of unit of measurement is very common to physics. Microchips based on the same concept in nanotechnology can revolutionize many areas.

Application
Today, nano forms of almost all materials, be they metals, non-metals, semiconductors, man-made substances like plastics, are made. Not only this, with the help of these nanomaterials, nano-drugs, nano-fabrics, nano-dyes have been gradually developed. Nanotechnology is not just about making different things. The ultimate goal of nanotechnology is to make a microscopic device by combining a single atom-molecule. The devices we use today, such as ball bearings, levers, engines, pumps, will be made of nanotechnology in future. Not only that, but their efficiency will also increase immensely. These devices will require very little energy to operate and will be powered mostly by solar energy. There will be a lot of new devices in the nano age that are not in today's age of micro technology and they will be very different from today's devices.
The U.S. military has invented a fingerprint sensor to detect whether the enemy has ingested toxic substances in food. This is called a biofinger.

The use of nanotechnology has greatly improved the way food is stored and preserved. Not only that, but in the future the use of nanotechnology will also affect the process of making real food. With the help of nanotechnology, we can prevent unwanted odors in mustard oil and other products.
Conclusion
Nanotechnology is currently the subject of much research around the world and is used in biology, ecology, free-ray electronics, electronics, cosmetics, and a few other fields. Which means in view of making a career this field has immense future potential. Nanotechnology is constantly revolutionizing new and newer areas. As in cancer treatment, this technology can help treat patients without radiotherapy or chemotherapy. Nanotechnology is also slowly being used in areas such as solar energy, batteries, electrical equipment, bio-conductor devices, as well as surface science, organic chemistry, and molecular biology.
But there is still a lot of research going on around the world in this field. Then there are opportunities for students to really pursue a career as a research scientist. Trainers and teachers are also in direct need of this new technology to reach out to others. Students pursuing Bachelors or Masters in Nanotechnology related subjects are in high demand in various industries in the international market.
