Cell viability and IL-1β release data for C57BL/6 AM cells exposed to various MWCNT for 24 hours. A) Mean ± SEM percent viable cells compared to no particle control condition. B) Mean ± SEM IL-1β as pg/ml. Asterisks indicate significance *** at P < 0.001, ** at P < 0.01 compared to both functionalized MWCNT variants at the same concentration. Daggers indicate significance ††† P < 0.001, †† at P < 0.01, † at P < 0.05 compared to the 0 μg/ml no particle control.
