Optical Microscopy & Spectroscopy
- Cellular imaging: we use a dual-color confocal microscope for time-lapse imaging of dynamic processes in cells or GUVs.
- Protein & lipid diffusion: the diffusion of lipids1,2 and proteins 2,3 is measured by fluorescence correlation spectroscopy (FCS) and fluorescence-recovery after photobleached (FRAP)-based methods.
- Transport through membrane pores: a method termed dual-color fluorescence burst analysis (DCFBA) has bee developed to probe (macro)molecular transport through mechanosensitive channels and peptide pores. Selective-FRAP is used to probe the in situ transport through the yeast nuclear pore complex.
