Investigation of the second phase of three-dimensional manipulation of gold nanoparticles using atomic force microscope on rough and smooth surfaces
The study of materials in nanomanipulation process is done in two phases with the aim of examining the motion of the particle before and after the motion. Studies have been performed on particles such as gold in the first phase and the critical force and time for this particle has been calculated according to different environmental and geometric conditions. In order to complete the process, in this paper, gold particle manipulation in the second phase is investigated. In this research, motion modeling has been done in three dimensions and particle motion has been observed on rough and smooth surfaces. Finally, using the results of modeling and manipulation of gold particles using atomic force microscope and due to the presence of elevations and heights in the nanoscale, the results show more displacement on smooth than rough surfaces and also according to the motion study. In both x and y directions, the displacement in the y direction was greater. Other results calculated in this study include the study of surface parameters and geometry of gold particles.
