Micro­systems & nano­tech­nology

The Microsystems & Nanotechnology Group operates the NMI cleanrooms. We specialize in the development and small-scale production of micro- and nanosystems for life sciences applications.

Special biostable electrodes made of titanium nitride and iridium as well as 3D electrodes are processed for these systems. Optical lithography, electron beam lithography, focused ion beam (FIB) and nanoimprint lithography are used for micro- and nanostructuring. Structures in the range of 20nm to 100µm can be generated.
