纳米,旧称毫微米,一纳米等于十亿分之一小的长度。研究纳米级物质(包括分子、原子、电子)的运动规律和内在运动特点,并利用这些特性制造特定功能产品的高新尖技术,就是现在在科技界的纳米技术。由于纳米技术最终使人类能够按照自己的意愿操纵单个原子和分子,以实现对微观世界的有效控制,因此被世界各国列为21世纪的关键技术之一。 Nanometer, formerly known as nanometer, nanometer is equal to one billionth of a small length. It is now nanotechnologies in the scientific community to study the movement patterns and intrinsic motion characteristics of nanoscale substances (including molecules, atoms, and electrons) and to use these characteristics to create high-tech technologies for specific functional products. As nanotechnology finally enables mankind to manipulate individual atoms and molecules as they wish to achieve effective control of the micro-world, it has been listed as one of the key technologies in the 21st century by all the countries in the world.
