Fig. 2From: Effects of differently shaped TiO2NPs (nanospheres, nanorods and nanowires) on the in vitro model (Caco-2/HT29) of the intestinal barrierCell viability (% of control) of Caco-2/HT29 co-culture barrier treated with 0–350 μg/mL of TiO2NPs-S (a), TiO2NPs-R (b), and TiO2NPs-W (c) for 24 or 48 h. Results were analyzed according to the one-way ANOVA with Tukey’s post-test and are represented as mean ± SEMBack to article page
