Abstract : I will begin my talk with a short overview of the activities of my group in Dresden, including some words on nanocrystal synthesis in colloidal solution, their characterization, properties and fields of applications. These applications will already include those which rely on surface functionalization and, hence, incorporation of particles into various matrices.

The main focus of my talk, however, will be will be laid on non-ordered superstructures made from nanocrystals. Here, gels and aerogels manufactured from a variety of different nanoparticles have recently proven to provide an opportunity to marry the nanoscale world with that of materials of macro dimensions which can be easily manipulated and processed, whilst maintaining some of the nanoscale properties. The materials carry an enormous potential for applications. This is largely related to their extremely low density and high porosity providing access to the capacious inner surface of the interconnected nanoobjects they consist of.
