Method for evaluating the normal force exerting on spherical bio molecules approaching to the biomolecular cellular receptor surface

摘要

A theoretical method was introduced for evaluating the normal force which is acting on a small spherical bio molecules approaching the bio membrane. The stream function and the Stokes equation for creeping flow for axisymmetric flow have been solved analytically with the boundary conditions of no slip on the solid plane as the biological membrane. By applying the Hankel integral transformation, we could obtain several mathematical forms such as uniform flow past two touching spheres of arbitrary sizes.
