Nanostructure is a new system based on nano scale material units and according to certain rules. It includes nano array system, mesoporous assembly system and film mosaic system. The research on nano array system focuses on the binary system formed by the orderly arrangement of metal nanoparticles or semiconductor nanoparticles on an insulating substrate. The assembly system of nano particles and mesoporous solids has become a research hotspot due to the characteristics of the particles themselves and some new effects generated by coupling with the matrix at the interface. According to the type of support, it can be divided into inorganic mesoporous complex and polymer mesoporous complex, and according to the state of support, it can be divided into ordered mesoporous complex and disordered mesoporous complex. In the film mosaic system, the main research on the nanoparticle film is based on the electrical and magnetic properties of the system. American scientists use self-assembly technology to make hundreds of single-walled carbon nanotubes into crystal rope "Ropes". This rope has metal characteristics, and its resistivity at room temperature is less than 0.0001 Ω/m; Nanometer lead triiodide was assembled on nylon - 11, which had photoconductivity under X - ray irradiation. This property laid a foundation for the development of digital radiography.
