Analytical description of nanoparticle motion near an elastic membrane — •Rebecca Benelli, Abdallah Daddi-Moussa-Ider, and Stephan Gekle — Biofluid Simulation and Modeling, Fachbereich Physik, Universität Bayreuth
We investigate analytically the motion of an extended nanoparticle near an elastic membrane endowed with shearing rigidity. For the simpler case of a point particle or rather a particle distant to the membrane this has been done recently1. Taking the conditions resulting from an elastic membrane and combining them with the description of the motion of an extended spherical particle near a fluid-fluid-interface2 leads to a linear equation system. This can be solved numerically in order to get the frequency dependent mobility of the particle.
