Description
The Leiden Institute of Chemistry wishes to purchase a Spinning Disc microscope. The primary tasks of this setup is to image live zebrafish larvae (0 to 12 days post fertilization) and to image (i.e. brightfield and fluorescence imaging) biological samples (cells, organoids, tissue (sections), organs like the brain of zebrafish) before and after expansion using published Expansion Microscopy (ExM) protocols with high speed, sensitivity and resolution. Our spinning disc microscope is intended to be used to image large numbers of zebrafish larvae at different developmental stages before and after injection of nanomedicines/drugs in the blood stream or directly into tissue/organs like the brain. The microscope should be able to image this in brightfield or using fluorescence with high speed, sensitivity and resolution. The spinning disc microscope will also be used to image cells, organoids, tissue (sections), organs like the brain of zebrafish before and after expansion of the biological sample. In the expanded state the density of fluorescent probes is very low and therefore a high sensitivity is required. Furthermore, these samples are similar to the zebrafish large in size (multip…
Award criteria
- Quality — The instrument will have the possibility to connect photo activation module
- Quality — The instrument will have the possibility to have multi magnification imaging.
- Quality — The instrument can have a unique filter for each fluorophore in the list above, for optimal imaging without spectral bleed through.
- Quality — The instrument should be easy to use by (non-expert) scientists after they received (initial) training by expert user.
- Quality — Sample loading (i.e. zebrafish larvae, expanded cells, tissue, organoids, organs) should be possible.
- Quality — The instrument should have automatic water dispenser system on all long W.D. objectives.
- Quality — The evenness of illumination on max field of view.
- Quality — The speed of acquisition over a set range of the sample.
- Quality — For cell tissue samples, the quality of the obtained images, with respect to signal intensity, as well as signal to noise.
