(A) Effect of NPs on the viability of human monocytes and HBMEC. Cells from human donors were isolated and cultured as described in the Methods, loaded with NP (1 to 500 μg/mL) for 48 h and toxicity was assessed over 24 h by the alamarBlue™ assay. Representative toxicity data at 24 h are shown. * p<0.05, *** p<0.001 compared to untreated controls. (B) Effect of NPs on the viability of N27 neurons. After incubation of NPs (1 to 1000 μg/mL) with N27 cells for 24 h, toxicity was assessed for 1 h by the MTS cytotoxicity assay. ** p<0.01, *** p<0.001 compared to untreated controls.
