Nano-meter is a length unit in Physics, also named as millimicron which is one billionth of a meter. To be visualized, if a granule of nano-meter size is put on a ping-pong, the rate is similar to put a ping-pong on the earth. Modern science research discovers: when substance is “crushed” to nano level, there will be occurrence of unexpected change. The produced “nano material” not only change the optical, electrical, heat and magnetic characteristic, but also possess many new characteristics such as radiation absorption, catalyzing, sterilization and absorption. These nano particles have larger size than their surface area, produce vast energy, and create many new functions and features as well. Nano technology can also be applied in genetic engineering such as: nano robot of needle point sized. Nano technology breeds with much potential that are difficult to estimate, It will bring enormous revolution to industry, agriculture, military, medicine, communication and community sectors. The relevant organization predicts that the nano products will overreach the computer products. In the present, Countries like Europe, United States and Japan has invested enormous amount to compete for the nano highlands.

Nano Technology – the most prosperous technology in the twenty-first century. It extends into the physics, chemistry, biology, electronic and mechanics in an irresistible trend. It can say without exaggeration that nano technology will sweep across the whole field of natural science. It will also create in-depth impact in social science and even in the whole human civilization. There is no reason to doubt that nano technology will stand at the commanding height of the era and lead the rolling terrent of new technologies in the twenty-first century.

In history, there were “Stone Era”, “Bronze Era”, and “Iron Era”…. There will be a Nano World in the twenty-first century.
