Gas (or air) embolism is a medical condition caused when gas bubbles are present in venous or arterial blood vessels, leading to limited or blocked blood and oxygen supply to...
Preprint

Gas embolism is a medical condition leading to the blockage of blood flow in the microvasculature by gas bubbles. While reported as rare, gas embolism often has devastating, fatal physiological consequences. Despite this acute importance, the genesis and evolution of air bubbles in blood vessels under different physiological conditions, such as blo...
Article
The exact positioning of micro/nanoparticles is essential in the construction of micro/nanoscale structures. Of course, the shape of a particle and the external force application location on it influence the type of behavior exhibited by that particle during its displacement on a surface. In former works, biological and non-biological particles hav...
Article
The imaging and manipulation tools being the same in an AFM has necessitated the modeling and simulation of the AFM-based manipulation processes. In earlier studies, the dynamic behavior of biological particles in the course of manipulation has been modeled and simulated two-dimensionally. Now, with the advancements made in the modeling techniques,...

This paper has attempted to investigate the effective forces in 3D manipulation of biological micro/nano particles. Most of the recent researches have only examined 2D spherical geometries but in this paper, the cylindrical geometries, which are much closer to the real geometries, were considered. For achieving a more accurate modeling, manipulatio...
Article
By using an atomic force microscope as an ideal instrument for the manipulation of biological particles, the user deprives herself of the direct observation of the manipulation process in real time. In order to understand this process and to remove this limitation, an auxiliary method should be adopted which itself is not hampered by such a constra...

The theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. In elastic deformation contact occurs over a finite area. A regular method for determining the dimensions of this area is Hertz Contact Model. Appearance of atomic force microscope results in introduction...
