Welcome to the Nanobiophotonics group

The Nanobiophotonics group is founded by the "Ministerium für Innovation, Wissenschaft, Forschung und Technologie" of the federal state of North Rhine-Westphalia.

The research activities are devoted to the development and application of nano-optical tools. A major interest is the investigation of membrane proteins in cellular structures and to understand the spatial and chemical organization of cellular membranes on the nanometer scale. This research can contribute to identify malfunction of specific membrane compounds, regulation processes and its correlation to specific diseases, e.g. neurodegenerative diseases such as Alzheimer‘s and Parkinson’s disease.The research activities are devoted to the development and application of nano-optical tools.

Nano-optical tools are of major relevance, since the high density as well as the pursuit of submicroscopic domain formation prevents the access to these quantities by common confocal microscopy due to the Abbe diffraction limit. In order to break this barrier of approximately 250 nm, different strategies will be employed. These include near-field as well as far-field techniques.

The group is currently seeking for bachelor, master and PhD candidates from different disciplines (physics, biophysics, nanotechnology, chemistry and related fields) to participate in this highly interdisciplinary field of nano-optics.
