The Imaging Core Facility has a set of microscopes and a bioimager to support the most common types of microscopy including fluorescence, laser confocal, phase contrast, and the elementary brightfield. Besides the Nikon inverted and upright microscopes, a BioTek Cytation 5 bioimager in this unit allows the imaging under UV-vis light in diverse sample holders and cell culture dishes, as well as running enzymatic kinetics and live cell visualization under temperature and CO2-controlled conditions.

A scanning electron microscope  (SEC SNE-4500M Plus) in this facility allows the magnification of samples up to 150,000 times at 5nm resolution. This 5-axis motorized instrument is coupled to an Energy-Dispersive X-ray Spectroscopy module (EDS/EDX) for chemical characterization and analysis of inert materials. Additionally, the optimal visualization of biological specimens by SEM is supported by a critical point dryer, which helps preserve sample morphology.
