Fig. 9.

Effect of carbon-encapsulated magnetic nanoparticles on LDH leakage in human dermal fibroblasts (HDFs). Cytotoxicity was determined by LDH release after 24 h of exposure to CEINs (0.0001–100 μg/ml). Data are mean ± SD. Significant ANOVA test among different CEIN types versus Fe@C/Fe type is represented by bracket with a asterisk over each data set (P < 0.05), asterisk above nanomaterial columns indicates statistically significant difference compared to untreated controls (P < 0.05). See Table 1 for CEINs labeling
