Super resolution: Elyra PS1 + AiryScan

Since 2018 IRB offers access to three modalities of Super resolution combined in a single System: the Elyra PS1+ Airyscan.

Airyscan: Technique of Image scanning microscopy with an array detector, it enables 1.7 factor resolution improvement in a confocal mode and compatible with live imaging and conventional fluorescence.

Resolution improvement in 2D and 3D.

SIM: Structured Illumination Microscopy. A factor 2x resolution improvement achieved by reconstructing various images with a grid illumination pattern. Suitable for live imaging although relatively slow.

Resolution improvement in 2D and 3D.

Single Molecule Localization Microscopy: aka PALM/STORM, dSTORM etc...

Using the blinking properties of certain fluorophores, each fluorophore can be localized with very high precision (20-30nm laterally, 50-60 axially). The final images reconstruct thousands of images containing dozens/hundreds of localisations.

Resolution improvement can go up to 10x, as compared to conventional microscopy, with suitably selected fluorophores.

SMLM is not suitable for live imaging, special sample preparation required.
