Methods and techniques used by the AK Steinem

If you are interested in using one of the below-listed methods, please contact Prof. Dr. Claudia Steinem.

Fluorescence microscopy


  • Epifluorescence microscopy

  • Confocal laser scanning microscopy
    (405-635 nm excitation, temperature controlled (0 to 60°C), FRET, FRAP)

  • Spinning disc confocal microscopy
    (405-639 nm excitation, EMCCD with single-photon detection at < 10 ms time resolution)

  • Scanning probe microscopy


  • Atomic force microscopy
    (can be combined with fluorescence microscopy)

  • Scanning ion conductance microscopy
    (non-invasive topographical and electrochemical surface analysis)

  • Film thickness and adsorption measurements


  • Reflectometric interference spectroscopy
    (optical thickness measurements using a white light source)

  • Surface plasmon resonance spectroscopy
    (optical waveguide spectroscopy possible)

  • Electrochemistry


  • Single channel measurements (planar patch clamp)
    (solvent-free and solvent-containing self-supported membranes, several parallel measurements, array scan)

  • Electrical impedance spectroscopy

  • Spectroscopy


  • UV-Vis spectroscopy

  • Fluorescence spectroscopy

  • FT-IR spectroscopy
    (ATR, PM-IRRAS, VCD, measurements on solids, liquids, and temperature controlled biological samples, diffuse reflectance on solids and powders)

  • Surface preparation techniques

    Evaporation unit

  • High vacuum coating system UNIVEX400

  • Sputter coater

  • Etching of porous aluminium oxide

  • Plasma cleaner

  • Protein biochemical methods

  • Cell culture (S1)

  • Protein expression, -purification and -analysis

  • Membrane model systems
