Nanoaggregates on surfaces structured by nanolithography — •Maik Vieluf, Harald Graaf, and Christian von Borczyskowski — Optische Spektroskopie und Molekülphysik, Institut für Physik, Technische Universität Chemnitz, 09107 Chemnitz

For detailed investigations of single nanoaggregates a suppression of the interaction among the aggregates is necessary. Such suppression can be reached by fixing the aggregates to a structured surface with a certain distance between the structures. We report on a structuring on nanometer scale by local anodic oxidation of self-assembled monolayers by atomic force microscopy (AFM). The oxide structures are selectively chemically modified to achieve functionalized nanostructures. These functionalized nanostructures are used to bind semiconductor or metal nanoparticles or supramolecular structures. Such structures are investigated by confocal microscopy to evaluate the optical properties.
