The aim of this paper is to develop and simulate elastic-perfectly plastic contact theories for proper determination and estimation of contact area in manipulation of micro/nano bioparticles. The nanoparticles studied in this paper are categorized into three different cancerous cell types, lowly (LNCaP) and highly metastatic human prostate cancer cells (CL-1, CL-2), two normal bladder cells (Hu609 and HCV29) and three cancerous bladder cells (Hu456, T24 and BC3726). First, Hertz elastic model, finite element, and Brake and Chang elastic-perfectly plastic models with two different elastic states were simulated for Hu609 and Hu456 cells, and the results were compared against each other. Then, material and geometry effects of particles during contact were taken into account. Additionally, contacts of micro/ nanoparticle-substrate and micro/nanoparticle-atomic force microscope tip were studied. The results of contact simulations indicate a meaningful difference in distinct models. It can be inferred from the difference between Brake and Chang elastic-perfectly plastic models and Hertz theory that the latter is unable to describe the contact behaviour of very soft bioparticles. In most of previous studies, elastic contact theories such as Hertz and JKR have been used to calculate mechanical properties of soft particles manipulation; for the first time, however, two Brake and Chang theories have been used here to calculate the mechanical properties of bioparticles and to simulate the contact mechanics for use in biomanipulation based on the atomic force microscopy.

“…During the past decades, beams have been one of the most important structures used extensively in engineering applications. With respect to recent developments in science and technology, the implementation of small beams whose characteristic dimensions and behaviour are in terms of micrometres and nanometres has been developed in the past two decades [1][2][3]. Currently, nano/microbeams are known as the key components in nano/micro-scale systems, because of their novel features such as low weight, small size, simple fabrication and high-frequency operation [4].…”

The size-dependent free vibration of nano/microbeams with piezo-layered actuators is analytically investigated. The size-dependent dynamic modelling of the piezo-layered beam is presented on the basis of the non-local continuum theory. Equations of the motion and boundary conditions of the beam are obtained by implementation of Hamilton's principle. Analytical solutions for natural frequencies and mode shapes are obtained as a function of the piezo-layered beam characteristic size and non-local size scale parameter. The size effects on the vibration behaviour of the beam are studied and it is found that the non-local parameter, length ratio and thickness ratio have significant effects on the free vibration of systems.

“…8,9 As the important role of contact mechanics in the simulation of nanomanipulation gradually emerged, the investigators tried to employ various contact theories in order to simulate and study the role of contact mechanics in the nanomanipulation process. Korayem et al performed sensitivity analyses on the Hurtado and Kim (HK) model and Lugre friction models used for the manipulation of nanoparticles and found out that relative to the Coulomb model, the critical force needed for the onset of movement diminishes by 15.87% and 22.22% and the critical time diminishes by 50% and 75% using the HK and Lugre models, respectively. Daeinabi and Korayem employed the models of contact nanomechanics to explore the indentation depth of spherical nanoparticles in manipulations based on the AFM.…”

Sci. Instrum. 80, 043709 (2009); This article has dealt with the development and modeling of various contact theories for biological nanoparticles shaped as cylinders and circular crowned rollers for application in the manipulation of different biological micro/nanoparticles based on Atomic Force Microscope. First, the effective contact forces were simulated, and their impact on contact mechanics simulation was investigated. In the next step, the Hertz contact model was simulated and compared for gold and DNA nanoparticles with the three types of spherical, cylindrical, and circular crowned roller type contact geometries. Then by reducing the length of the cylindrical section in the circular crowned roller geometry, the geometry of the body was made to approach that of a sphere, and the results were compared for DNA nanoparticles. To anticipatory validate the developed theories, the results of the cylindrical and the circular crowned roller contacts were compared with the results of the existing spherical contact simulations. Following the development of these contact models for the manipulation of various biological micro/nanoparticles, the cylindrical and the circular crowned roller type contact theories were modeled based on the theories of Lundberg, Dowson, Nikpur, Heoprich, and Hertz for the manipulation of biological micro/nanoparticles. Then, for a more accurate validation, the results obtained from the simulations were compared with those obtained by the finite element method and with the experimental results available in previous articles. The previous research works on the simulation of nanomanipulation have mainly investigated the contact theories used in the manipulation of spherical micro/nanoparticles. However since in real biomanipulation situations, biological micro/nanoparticles of more complex shapes need to be displaced in biological environments, this article therefore has modeled and compared, for the first time, different contact theories for use in the biomanipulation of cylindrical and circular crowned roller shaped micro/nanoparticles. The results of models indicate that the contact model of Hertz achieves the largest amount of deformation for the DNA nanoparticle in cylindrical form and the contact model of Heoprich achieves the largest deformation for the circular crowned roller shaped DNA. Of course, this finding is not always true for the other nanoparticles; and considering the mechanical and environmental characteristics, different results can be obtained. Also, by comparing the deformations of different types of nanoparticles, it was dete...
