Sequential oxidation and functionalization of nanostructures: the site-specific controlled assembly of different sized particles on a surface

In this contribution the formation of nanostructures consisting of two differently sized nanoparticles is reported which is a crucial step towards the directed preparation of functional devices as the presented technique not only allows for the use of a wide range of materials but also combines site-specificity with the possibility to sequentially construct architectures consisting of multiple components without affecting previously deposited structures.
