Abstract
The boundary effect on the electrophoretic behavior of a particle is examined by considering a sphere at an arbitrary position in a spherical cavity for the case of low electrical potential and weak applied electric field. Here, a charge-regulated model is used to describe the charge conditions on the particle surface. This model finds practical applications where the behavior of biocolloids such as cells or microorganisms and entities covered by an artificial membrane need to be simulated. The two idealized models often used in relevant studies can be recovered as the limiting cases of the present model.
