Structural and dimensional characteristics of fullerene C60 dispersions in dimethylformamide were realized by transmission electron microscopy. All samples demonstrated the presence of fractions of fine and large C60 aggregates with sizes in the range of ~3 nm - 1.5 pm. The dependency between the aggregates’ sizes and concentration of the dispersions was demonstrated. The increase of amount of large aggregates and growth of their sizes (from ~0.5 to 1.5 pm) was revealed for fullerene in concentration range of 20-50 pg/ml. The size of fine aggregates of nanoparticles was similar in all dispersions. The average diameter of fine aggregates was about 10 nm. The data obtained from the characteristics of fullerene dispersions is of interest for the planning of studies involving the introduction of fullerene in biological systems.
