Resumo

We studied the effect of fullerenol C60(OH)22–24 on the viability of human peripheral blood monocytes and its adhesion/internalization by these cells. Nanoparticles at concentrations of 0.25, 0.5, 2.5, 5, 12.5, 25, 50, 100, and 200 μg/mL were incubated with human blood mononuclear cells for 24, 48, and 72 hours (5% CO2 at 37°C). We subsequently determined monocyte viability and fullerenol fluorescence intensity in the monocyte gate using flow cytometry. Nanoparticles were adsorbed/internalized by cells proportionally to their concentration and incubation time. Fullerenol С60(ОН)22–24 at 200 μg/mL reduced monocyte viability by an average of 17%, 30%, and 28% after 24, 48, and 72 hours, respectively. Cell survival inversely correlated with nanoparticle uptake intensity. Concentrations ≤100 μg/mL did not exhibit cytotoxicity even after prolonged exposure, supporting its biomedical applicability.
