Fig. 2From: In vitro inflammation and toxicity assessment of pre- and post-incinerated organomodified nanoclays to macrophages using high-throughput screening approachesPre- and post-incinerated uncoated (CloisNa) and organomodified (Clois30B) montmorillonite nanoclay particle morphology under FESEM and TEM imaging. As-produced nanoclays possessed exfoliated (white arrows) and stacked platelet morphology while I-CloisNa showed amorphous pyrogenic silica morphology. I-Clois30B possessed a mixture of amorphous and retention of stacked platelet morphology, similar to crystalline silica (CS)Back to article page
