There is information about fullerenes biological activity and their toxicity, although in most works the toxicity of the unmodified substances is exposed to the doubt.

The preparation of colloid solutions of С60 and С70 fullerene mixture, as well as the chemical composition and properties of the resulted sols are described. It has been found that the ratio of fullerenes С60 and С70 does not change on going from a solid phase into colloid solution. It has been shown that the obtained sols are resistant for water bath boiling and UV irradiation procedures. It has been also found that the properties of colloid solutions (micelle size and ability to aggregation) depend on their preparation conditions, in particular, on the time between preparing intermediate toluene solution of fullerenes and transfer of them into colloid solution. The studies have shown that colloid solutions of fullerenes possess substantial antioxidant properties, at the same time they do not possess any noticeable cytotoxic or antiproliferative effect on cell culture.

Key words: fullerenes, colloid solutions, biological and antioxidant activities.
