纳米科学技术是研究在千万分之一米(10-8)到亿分之一米内，原子、分子和其它类型物质的运动和变化的学问，同时在这一尺度范围内对原子、分子进行操纵和加工又被称为纳米技术。纳米是尺寸或大小的度量单位：千米（10-3）→米→厘米→毫米→微米→纳米（10-9）。它只有4倍原子大 Nanotechnology is the study of the movement and changes of atoms, molecules, and other types of matter within a millionth of a meter (10-8) to one hundred millionth of a meter, and at the same time, atoms and molecules are carried out within this scale Manipulation and processing are also known as nanotechnology. Nano is a measure of size or size: kilometer (10-3) → meter → cm → millimeter → micron → nanometer (10-9). It is only 4 times larger than atomic
