Advanced Light Microscopy

The mission of the Advanced Light Microscopy (ALM) national unit is to give support with superresolution fluorescence microscopy for nanoscale biological visualisation (SIM, STED, SMLM, ExM, MINFLUX). In addition the unit support single molecule measurement and analysis with fluorescence correlation spectroscopy (FCS/FCCS/FRET-FCS), and combined with superresolution for nanoscale dynamical studies (STED-FCS, MINFLUX tracking). Moreover, support with light-sheet fluorescence microscopy (LSFM) allow users to image live and/or optically cleared larger samples at unprecedented volumetric speed with low phototoxity. Single cell ultra-fast volumetric imaging of biological processes at high-resolution is provided by lattice light-sheet microscopy (LLSM).

Services

Support is done to all stages of the project including (pre)planning, sample optimization, fluorescent probe selection, image acquisition, and initial post-acquisition image processing.

Super-resolution microscopy (SIM, STED, SMLM, ExM, MINFLUX) – nanoscale cellular imaging of fixed or living samples, and cleared/expanded tissue.
Fluorescence Correlation Spectroscopy – single molecule spectroscopy measurement and analysis to evaluate interaction, aggregation, mobility, dynamics.
Light-sheet microscopy – fast, volumetric imaging of organoids, model organisms and cleared/expanded tissues.
Lattice light-sheet microscopy – fast high-resolution volumetric imaging of cellular processes in mammalian and plant cells.

Transfer of unique knowledge to individual researchers are supported nationally, including organization of workshops and courses in advanced fluorescence imaging and spectroscopy applications and method developments.
