Adhesion of biomimetic microcapsules — •Fery Andreas, Nils Elsner, Marc Nolte, Ashok Raichur, and Helmuth Möhwald — Max Planck Institut für Kolloid und Grenzflächenforschung

Polyelectrolyte multilayer capsules can be designed in their compliance and in their interactions, which makes it possible to control their adhesion behavior. The size of adhesion areas and the geometry of adhering capsules can be studied using microinterferometry. While we have investigated adhesion triggered by electrostatic interactions in detail, we present first results on adhesion triggered by specific interactions. On homogenous substrates, we can study the impact of interaction strength and nature of interaction on adhesion. Patterned substrates can be used to direct microcapsule adhesion. In this way, self assembled arrays of immobilized capsules can be formed.
