the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

We derive the general expression for diffusiophoretic mobility of a soft particle (i.e., polyelectrolyte-coated hard particle) in concentration gradient electrolytes case which particle’s core size is large enough compared with Debye length. Therefore, surface can be regarded as planar, and electrolyte parallel to surface. The obtained applied arbitrary values fixed charge density polyelectroly...
