The manipulation of nanoparticles is a current topic of research in the nano world. This is an important subject, since by displacing the nanoparticles, a structure different from the one which is currently available can be obtained. To achieve such a purpose, the atomic force microscope (AFM) is employed as a manipulator to push or pull the target nanoparticles on a substrate and get them to the desired locations. The important point in this process is the amount of force which is necessary to move a particle to the intended spot. Also, to estimate the time for the onset of nanoparticle movement in the sliding mode, it becomes important to obtain the critical time as well. In this paper, through the dynamic simulation of a nanoparticle, its governing manipulation equations have been derived and simulated, so that they can be applied to determine the critical force and time for gold, yeast and platelet nanoparticles in gas, liquid, alcohol, and plasma mediums. Another important issue in the manipulation of nanoparticles is the control of the AFM probe. So, we propose to use an appropriate input such as the torque applied to the probe tip in order to control the probe deviation from its center and to observe the amount of probe displacement along its vertical direction so that, during the moving operation, the AFM probe always remains in contact with the nanoparticle being displaced. This control issue has been investigated for various liquid environments and with different biological and non-biological nanoparticles. Furthermore, the probe of the AFM has been controlled B M. H.

“…The manipulation of nanoparticles is aimed at obtaining the critical force and time of displacement for these particles; this requires the selection of an appropriate friction model for contacting surfaces. For this purpose, in another study, Korayem et al 11 investigated the sensitivity of advanced frictional models such as Hurtado–Kim (HK) and LuGre in the AFM-based manipulation of nanoparticles. The graphical SA results indicated that the critical force and time of movement in the HK and LuGre models are less than those in the Coulomb model.…”

Investigating the effective parameters in the Atomic Force Microscope–based dynamic manipulation of rough micro/nanoparticles by using the Sobol sensitivity analysis method

Due to the substantial complexities of atomic force microscope (AFM)-based dynamic manipulation models, these models require the identification of many parameters and inputs with varying levels of sensitivity. Various sensitivity analysis (SA) methods can be used to achieve such a goal. The Sobol method is one of the famous SA approaches based on variance, which is widely used today in various study and scientific fields. The dynamic models for the manipulation of micro/nanoparticles, which have been investigated in previous works by means of the SA methods, have involved spherical nanoparticles with smooth surfaces. Since different micro/nanoparticles have a variety of geometries and since surface roughness plays a significant role in the contact of these particles with different surfaces, in this paper, the sensitivity of the AFM-based dynamic manipulation model of rough micro/nanorods has been analyzed. By considering more diverse geometrical conditions for the target micro/nanoparticle, including a cylindrical geometry and rough surfaces, many geometrical parameters enter the model. Therefore, in this study, simulations have been performed by the Sobol SA approach in order to determine the sensitivity of the input manipulation parameters to the critical output values of manipulation, for the two groups of AFM and environmental parameters. Based on the results obtained from these simulations, cantilever thickness constitutes the most sensitive parameter in the manipulation of rough cylindrical micro/nanoparticles. By analyzing the sensitivities of environmental parameters, it was found that the parameter of surface roughness in the range of 0–0.04 is highly sensitive for rough cylindrical micro/nanoparticles.
