Figure 1

The viability of LBC3 (A,C,E) and LN-18 (B,D,F) cells treated with different concentrations (12.5 to 1000 μg/mL) of SiNPs in three different sizes: 7 nm (A,B), 5–15 nm (C,D) and 10–20 nm (E,F), for 24 and 48 h. Graph (G) presents the viability of human skin fibroblasts incubated with different concentrations, from 12.5 to 1000 µg/mL, of 5–15 nm SiNPs, for 24 and 48 h. Mean values from three independent experiments ± SD are presented. Significant alterations are expressed relative to controls and marked with asterisks. Statistical significance was considered if * p < 0.05.
