纳米是一种度量单位。 1纳米为 1/100万毫米（即 1毫微米），为 1/10亿米。纳米结构通常是指尺寸在 100纳米以下的微小结构，在这种水平上对物质和材料进行研究处理的技术称为纳米技术。纳米技术其实就是一种用单个原子、分子制造物质的科学技术。纳米技术是被国际上公认的 21 Nanometer is a unit of measurement. One nanometer is 1 millionth of a millimeter (ie, 1 nanometer), which is 1/10 billion meters. Nanostructures are often referred to as microstructures below 100 nanometers in size, at which level the technology for studying materials and materials is called nanotechnology. Nanotechnology is actually a kind of science and technology that uses a single atom or molecule to make matter. Nanotechnology is internationally recognized 21
