Effects of extractive media on cell survival. Analysis of cell viability in cultures of L-929 cells ( individual experiments) and R28 cells ( individual experiments) incubated for 24 hours with increasing serial dilutions of extractive media obtained from different wafer slices (blank, MWCNT-Fe, MWCNT-Fe-Pt, and MWCNT-Fe-Ti) and certified positive (RM A, RM B) and negative (RM C) reference materials. Extractive medium without the incubation of any material (glass) was used as internal negative control; its mean values are marked by the dotted lines. Data are represented as mean ± SD. They were compared to the glass control and analyzed using unpaired two-tailed test. (a) , RM A and RM B; , blank. (b) , RM A and RM B. (c) , RM A; , RM B. (d) , RM A. (e) , RM A. (f) , RM A.
