Abstract
By means of computer simulations, this work addresses adhesion of a deformable spherical capsule to a micro-rough surface consisting of a periodic array of pillars. Depending on the micro-relief topography, three different adhesion regimes have been observed: 1) weak adhesion without deformation of the membrane (fakir state); 2) strong adhesion with deformation of the capsule membrane and binding to the bottom wall (nested or contacting state); 3) impalement of the capsule by micropillars. It has been found that a periodic micro-relief implies a favorable positioning of the capsule on rough surfaces.
