The importance of nanomaterials and nanotechnology in the field of science and technology, their research significance and development perspectives were emphasized. Four basic properties of nanoparticles, i.e. surface effect, volume effect, quantum size effect and macroscopic quantum Tunneling effect, were introduced briefly. Present application status of nanomaterials in chemical industry, light industry, functional material and biomedicine, the usage perspectives were described. Some examples were given in this article, which make a clear demonstration of its role in social progress and science development. Based on the state differences of the raw materials, preparation methods were divided into three main types called solid phase, liquid phase and gas phase respectively. At the same time, methods of nanoparticle preparation and application of nanomaterials appearing in many other literatures were also listed. The characteristics of these methods and their application range were discussed. The perspectives of nanomaterials in science future were depicted as well.
