  AFM

AFM Bruker Bioscope Resolve mounted on a Leica DMi8 inverted optical microscope.
Analysis of samples (organic, inorganic, cells, ...) in air, in organic solvent (hexane, isopropanol, octadecene, octylether etc) or in liquid with temperature control.
    Modes:
    - Imaging/Topography of surfaces (resolution: nm).
    - Force spectroscopy (resolution: pN) and mapping of mechanical and adhesive properties (single-molecule and single-cell force spectroscopy).
    - PFT-QNM (peak force tapping - quantitative nanomechanical mapping): simultaneous mapping of mechanical properties and topography.
    Correlative analysis:
    - Inverted microscope DMi8 Leica for optical and fluorescence analysis (Obj. 20x, 40x, 63x).
    - Raman micro-spectroscopy (on-going)

  AFM
