纳米技术是在单个原子、分子层次上对物质进行精确的观测、识别与控制的研究和应用技术。纳米技术的研究对象是纳米级尺度的物体。纳米是国际单位制的长度单位,一纳米就是一毫微米,等于一米的十亿分之一。纳米技术的基础是与单个原子、分子测控技术密切相关的,它是在单个或极少数原子、分子组合体的微观层次上 Nanotechnology is a single atomic, molecular level on the material for accurate observation, identification and control of the research and application of technology. Nanotechnology research object is nano-scale objects. Nano is the unit of length of the International System of Units, a nanometer is a nanometer, equal to one billionth of a meter. Nanotechnology is based on a single atom, molecular measurement and control technology is closely related, it is in a single or very few atoms, the molecular combination of micro-level
