From: Nanomaterial cytotoxicity is composition, size, and cell type dependent
Nanomaterial induced apoptosis and necrosis in 3T3, hT and RAW cells. Annexin V-FITC/PI double staining was performed to distinguish 3T3, hT and RAW cells undergoing (a) Apoptosis and (b) necrosis following 20 hours of exposure to all nanomaterials at 100 μg/ml. For each nanomaterial, bracket with a (*) indicates significant difference between different cell types by ANOVA. (*) above nanomaterial columns indicates significant difference from untreated/control cells by Bonferroni test.
