For the same cell lines, and under the same conditions, it was found that the high cytotoxicity of nano-C60 was not a universal property of C60 materials.
Since our investigation is related to the new materials for cosmetic and medical applications, their effect on very sensitive tissue, like eye tissue, should be tested.

Four sheet materials were tested; their principal characteristics are summarized in Table 1.
The two sheet materials with 2 mm thickness were the most thoroughly investigated.
The results for all the materials are overlapped in order to observe the general trends.
