Molecularly defined nanostructures can be self-assembled at surfaces a
nd interfaces from suitably designed macromolecules, making use of a c
ombination of intra-and intermolecular as well as interfacial forces.
Advances in understanding and mastering scanning probe microscopies re
nder it possible to analyze macromolecules at solid-liquid interfaces
quite generally on a molecular scale. This forms an important basis fo
r the rational development of self-assembly as a fabrication process.
