The Advanced Light Microscopy Unit (ALMU) is a walk-in core unit on a mission to help, support and educate the research community from CRG and beyond to do quantitative bioimaging. We provide support on a range of technologies starting from experimental design, sample preparation, acquisition, bioimage analysis and visualization.

Our unit consists of microscope systems specifically designed for fluorescence microscopy ranging from confocal, widefield to super-resolution systems and helps reveal structures from macro to the nanoscale.

Quantitative Light Microscopy Course (20-24/02/2023)

ALMU together with the CRG training team is organizing the very first Quantitative LightMicroscopy Course. This unique course covers the entire spectrum of bioimaging, starting from the fundamental basis of optical microscopy, instrumentation, specimen preparation, molecular markers, right up to the most recent and revolutionary development in bioimaging and bioimage data analysis, including artificial intelligence in microscopy. For more information follow the link here.



IXplore SpinSR workshop with Evident/Olympus (04/05/2022)
ALMU hosted the IXplore SpinSR workshop that presented the latest advances in multi-modal confocal spinning disk imaging of live cells and tissues in super-resolution mode.
May 4: Virtual seminar covering the IXplore SpinSR system capabilities and highlighting the super-resolution technology. Followed by a virtual live demo of the system.

CRG at the Dubai Expo Spain Pavilion (03/2022)
Nadia Halidi has joined forces with Neoalgae, an Austrian biotechnology company, and The Others TV, an animation studio based in Barcelona to showcase the potential of microalgae as a sustainable future solution. The movies were acquired with a high-speed camera using darkfield microscopy with components provided specifically for this project by Carl Zeiss Iberia S.L. The production was showcased in the Spain Pavilion at the Expo 2020 Dubai from October 2021 to March 2022.
