Template-Directed Self-Assembly of Nanoparticles — •Alexander Böker, Günther Jutz, Nathalie Mougin, and Sergej Koutouzov — Physikalische Chemie II, Universität Bayreuth, 95440 Bayreuth, Germany

We report on the general concept of nanoparticle self-assembly at templating interfaces. Inorganic cadmium selenide as well as organic particles like ferritin and cow pea mosaic virus (CPMV) are employed as building blocks for three-dimensional assemblies. The self-assembly kinetics is followed by in-situ GISAXS or pendant drop tensiometry depending on the type of interface. The resulting structures are imaged using cross sectional TEM. In addition, several methods (crosslinking, mineralization, etc.) are described to lock the particle assembly into place and construct mechanically robust nanoporous capsules and membranes which are characterized using TEM and SEM.
