  • Modelling anisotropic interactions in colloidal systems

    • There has been an increased interest to design “smart materials” which can self-assemble into complex structures in accordance to external factors such as for example electromagnetic fields. By designing particles with directional interactions one is able to control how particles will interact with each other. By means of both Monte Carlo and Molecular Dynamics simulations we study the interactions of three distinct types of models namely the self-assembly of off-centered dipoles, the charged patchy particle model in multivalent electrolytes, and an all atom model of [3,3Õ-cobalt(III) bis(1.2-dicarbollide)] and its interaction with solvent. Besides this there is also a short discussion about the long-range anisotropic interactions and ways by which one can calculate them.

    • Proteins and many recently designed colloids can be regarded as patchy particles where directional interactions strongly influence and govern assembly behavior. Using explicit ion implicit solvent Metropolis Monte Carlo simulations, we investigate spherical model particles, carrying both charge and electric patches, in dilute aqueous 1 : 1, 1 : 3, and 3 : 1 electrolyte solutions. Striking differences in pair interaction free energies and orientational correlations are induced by three different salts which are discussed and rationalized in terms of ion-binding to surface groups, ion-ion correlations, and double layer forces. These findings suggest a general strategy where directional, intermolecular interactions can be invoked and tuned via small amounts of a carefully chosen electrolyte.
