Svetlana Santer commenced her studies in Physics at the University of St. Petersburg, Russia and graduated with a „Master of Science“ in biophysics with the thesis: “On the interaction of Anti-Tumor-Compounds with single DNS- molecules”. For her PhD work, she joined the group of Prof. Martin Möller in Ulm where she carried out novel studies concerning thin polymer films and single synthetic and bio-molecules at surfaces, extensively exploring the methodology of atomic force microscopy. After she received her PhD in October 2000, she joined the group of Prof. Jürgen Rühe at the Institute for Microsystem Technology (IMTEK) of the University of Freiburg working on the problems concerning the "Synthesis and Surface Modification of Nanoparticles".
In 2003 she received a habilitation stipend from the Margarete-von-Wrangell foundation and  worked until 2008 as a senior scientist in the laboratory of Chemistry and Physics at Interfaces at the Institute of Microsystem Technology (IMTEK, Freiburg). In October 2007 she passed her qualification as a university teacher (“Habilitation”) working on developing novel concepts to employ functionalised surfaces to move and/or arrange and assemble adsorbed nano-size objects. She is furthermore the head of the service group „Interfaces and Surfaces“ at the Freiburg Center for Materials Research (FMF).
In 2008, she joined the Freiburg Institute for Advanced Studies (FRIAS) at the Albert Ludwigs University in Freiburg, Germany, where she holds a junior research fellow position in the School for Soft Matter Research. The general focus of her research is on fundamental phenomena in the field of soft matter at surfaces and on measurements and quantitative description of interactions between nano-particles and polymer surfaces.


SPINAL: Surface plasmon interference nano-lithography

At FRIAS it is planned to develop novel photoactive functional thin polymer films with integrated metal gratings sensitive to the excitation of surface plasmons. Upon UV-illumination, the photosensitive groups not only respond to the primary external radiation, but also to the secondary emission of UV-light by surface plasmon giving rise to interference patterns and light density distributions below the diffraction limit. In this way, the topography of the thin polymer films can be manipulated in an unprecedented way on a nano metre scale. This opens up several new possibilities in the field of nano manipulation. By imposing a time-dependent protocol on corresponding topography changes in response to variations in irradiation, it should be possible to supply dynamically reconfigurable surface force fields.
