In this paper, a fine particle manipulation system using a piezoresistive microcantilever, which is normally utilized in Atomic Force Microscopy, as the manipulator and force sensor, and a top-view Optical Microscope (OM) as the vision sensor is proposed. Modeling and control of the interaction forces among the manipulator, particle and surface have been realized for moving particles with sizes less than 3 µm on a silicon substrate in 2-D. The microcantilever behaves also as a force sensor which enables contact point detection, real-time force measurements, and surface alignment sensing. A 2-D OM real-time image feedback constitutes the main user interface, where the operator uses mouse cursor and keyboard for defining the tasks for the cantilever motion controller. Preliminary particle manipulation experiments are demonstrated for 2.02 and 1 µm gold-coated latex particles, and it is shown that the system can be utilized in 2-D micro particle assembling.

“…Baur et al moved gold nanoparticles at room temperature and at ambient conditions on a mica substrate and were able to construct several letters of the alphabet by manipulating these gold nanoparticles [2,3]. Sitti presented a model for the semiautomatic control of contact nanomanipulation, in which the JKR model was employed for determining the deformations of the contact surfaces, and the displacing of a nanoparticle was semiautomatically controlled [4,5]. Burnham and Kulik [6] explored the subject of mechanics of contact, and by using a mass and spring model to simulate the contact between a sample surface and probe, they derived the relevant equations.…”

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.

“…Furthermore, its high precision and repeatability facilitated a revolutionary breakthrough for biomedicine [3]. However, current nanorobotic systems are mostly semi-automatic dominated by manual operation and remote control [4][5]. Some fully-automatic control systems have been developed for nano-manipulation, but most of them equip with single manipulator, which is hardly to implement complex tasks [6][7][8][9].…”

Robotic nanomanipulation has achieved a wide range of applications on biomedicine and facilitated a revolutionary breakthrough for it. This paper presents a dexterous nanomanipulation system with three robots coordination for the reconstruction of three-dimensional (3D) artificial microstructure. It is set up with two main components. One is the nanomanipulator with 4 degrees of freedom (DOFs) and 30nm operation precision. The other is a vision sub-system developed to provide feedback for coordination control among the three robots. Based on the cooperation, we propose a pick-up method of 2D hydrogel microunits and integrate an assembly strategy to fabricate a 3D substitute for tissue engineering. Pickup of 2D microstructures largely determines the success of 3D assembly. Therefore, effectiveness of pick-up is investigated by kinetic analysis, Matlab simulation and pick-up experiments. These results demonstrate that the proposed method is feasible for circular 2D structure assembly. However, it is not universal for any shapes of 2D units. Thus, three new pick-up methods are discussed to seek for higher flexibility of our system.
