The Nanobiosensorics Lab focuses on the development and application of label-free optical biosensors and combines these technologies with single cell manipulation techniques. Their research topics are ranging from the kinetics of cellular adhesion, migration and signalling on novel biomimetic interfaces to the mathematical modelling of the measured biological signals.
Aim of their research:
Monitoring biomolecular or cellular interactions at the nanometer length scale opens up several challenging applications in basic biological, chemical, and biophysical research with significant industrial relevance in the health and biotechnology-related areas. It is especially useful when the processes and interactions are monitored by a label-free method.
The field of single-cell biology is rapidly growing, and in life sciences, there is a clear need to develop label-free sensors capable of monitoring single cells in real time. In the present project, we combine novel label-free devices with single-cell manipulation techniques in a unique yet unprecedented manner. We will focus on the experimental observation of single-cell behavior using high-throughput label-free optical biosensors and automated phase contrast and fluorescent imaging in combination with FluidFM and CCMP.
Topics:
1. Label-free biosensors – instrument and methodology developments
2. Coatings and their detailed characterization.
3. Biochemical examination of cell adhesion.
4. Mechanisms of active substances and stimuli.
5. Immune cell tests with biosensors.
6. Analytical and numerical modeling of biosensor data.
7. DNA tests.
8. Molography.
