Research Topic: In this research project we investigate and
develop novel micro- and nanofluidical chip device applications that can be used for separation, sorting
and harvesting of macromolecules and colloids. We use structured micro- and nanofluidic environments
and drive the molecular objects far from thermoddynamic
equilibrium to explore non-linear migration mechanisms like absolute negative mobility,
dielectrophoretic trapping, molecular ratcheting or chiral separation.
In addition, we design and develop lab-on-a-chip devices where individual cells like E. coli can
be trapped and analyzed according their active metabolism by UV-laser-induced fluorescence. |
