Visualization of CNP aggregates in the proximity of collected organs by stereomicroscopy. In the connective and lipid tissue of the spleen serosa, small dots (1 μm), and groups (up to 2 mm) of graphene oxide nanoparticle aggregates were formed (a) and (b). Small dots (1 μm), groups (up to 2 mm), and aggregates (up to 1 mm) of graphite nanoparticles were formed in the connective and lipid tissue of the liver serosa (c) and (d). Black arrows indicate CNP aggregates
