纳米级制造技术简称纳米技术（nanometer technology），是指物理空间在十亿分之一米（10-9米，纳米，也有叫毫微米的）范围的产品及制造技术，由于物理空间的改变，物质的理化特性，生物学特性发生令人惊奇的变化，科学界利用这一手段达到一般方法无法实现的目的。这一技术从1 Nano-scale manufacturing technology, referred to as nanometer technology, refers to products and manufacturing technologies whose physical space is in the range of one billionth of a meter (10-9 meters, nanometers, also called nanometers), due to changes in physical space, The physical and chemical properties of the material and its biological characteristics have undergone a surprising change. The scientific community has used this method to achieve the objective that the general method cannot achieve. This technique from 1
