What is nanotechnology?

A basic definition would be: Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced. In its original sense, “nanotechnology” refers to the projected ability to construct items from the bottom-up, using techniques and tools being developed today to make complete, high performance products. Nanotechnology is the engineering of tiny machines. Ultimately, nanotechnology will enable control of matter at the nanometer scale, using mechanochemistry. Shortly after this envisioned molecular machinery is created, it will result in a manufacturing revolution, probably causing severe disruption. It also has serious economic, social, environmental, and military implications. Mike Roco of the U.S. National Nanotechnology Initiative has described four generations of nanotechnology development. The current era, as Roco depicts it, is that of passive nanostructures, materials designed to perform one task. The second phase, which we are just entering, introduces active nanostructures for multitasking; for example, actuators, drug delivery devices, and sensors. The third generation is expected to begin emerging around 2010 and will feature nanosystems with thousands of interacting components. A few years after that, the first integrated nanosystems, functioning (according to Roco) much like a mammalian cell with hierarchical systems within systems, are expected to be developed. Nanotechnology as we know it will be the upgrade in technology and in human life. From finding new ways to invent a smaller computer to launching cells into your body to seek out the cancer cells without destroying the human tissue.

Why do we need nanotechnology in our daily life?

Molecular manufacturing (MM) can solve many of the world’s current problems. For example, water shortage is a serious and growing problem. Most water is used for industry and agriculture; both of these requirements would be greatly reduced by products made by molecular manufacturing. Infectious disease is a continuing scourge in many parts of the world. Simple products like pipes, filters, and mosquito nets can greatly reduce this problem. Information and communication are valuable, but lacking in many places. Computers and display devices would become stunningly cheap. Electrical power is still not available in many areas. The efficient, cheap building of light, strong structures, electrical equipment, and power storage devices would allow the use of solar thermal power as a primary and abundant energy source. Environmental degradation is a serious problem worldwide. High tech products can allow people to live with much less environmental impact. Advanced nanotech can solve human problems such as improving housing and plumbing will increase health.

What can be done with nanotechnology?

Nanotechnology can be used to make stronger buildings, or make better computers. It can also: solve many diverse problems that are related to water, cheap greenhouses can save water, land, and food. Nanotech makes solar energy feasible. Computers will be cheap enough for everyone. These are just some things scientists believe that nanotechnology can do. But I believe there could be a whole lot more done with nanotechnology.

Conclusion

I really think that nanotechnology will make an impact on human life. And just imagine all the wonderful things that nanotechnology can invent. I already gave you one idea about a pill that can cure any kind of diseases. That will go down in history of medicine. I’m also really happy that I join the nanotechnology program to help my understanding of technology, molecules and science. And maybe by developing the pill I could be the one to make a difference of mankind. J.W.
