Newly developed methods such as iDISCO have made it possible to image deep into complex organ systems (such as the brain) by making the organ optically transparent. This method requires the use of solutions containing a higher refractive index (RI), a measure of how much light scatters upon hitting said solution. However, current methods for mounting biological specimens for imaging on fluorescence microscopes use chambers compatible with solutions containing a low RI. Attempting to image optically cleared organs in these chambers result in mispositioned light that limits the imaging resolution and effective imaging area.
Researchers at UC Irvine have developed a new system that allows for the imaging of large biological specimens in high refractive index solutions on the Zeiss Z.1 fluorescence light sheet microscope. This new imaging system allows for improved optical sectioning in high RI solutions, increased imaging speed for larger samples, and imaging of larger biological samples via a larger chamber volume and new specimen mounting hardware. This will allow for high-resolution, fast, 3-dimensional imaging of whole brains, featuring new software and hardware specs compatible with the Zeiss Z.1 fluorescence light sheet microscope.
