Abstract
Nano-materials fabricated chemically or biologically are usually kept in liquid or solution. The characterization of these materials, especially about their dimensional scales, is important to the study of the materials as well as their further application. In this research, the dimensional features of a typical biomacromolecule nano-material are characterized by AFM in air mode and the uniformity is analyzed. Some dry samples are prepared for air mode measurement. The height of sample structure, h is (2.252±0.021) nm. The respective deviation of the overall structures' heights and of the section heights in single structure is 0.023 nm, and 0.021 nm, which shows ideal homogeneity of the material and good uniformity of the structure.
