Viability assays. (a) 600 nm absorbance increase after 12 hours’ E. coli cell growth in LB at 30°C in the presence of HAp, 7ZnHAp, and 10ZnHAp at concentrations between 1.95 and 1000 μg/mL. (b) HepG2 viability after 24 h exposure to HAp, 7ZnHAp, and 10ZnHAp at concentrations between 62.5 and 1000 μg/mL. Error bars are calculated from at least 3 independent experiments.
