Morphological analyses of titanate nanomaterials. Titanate nanomaterials were dispersed in distilled water at a concentration of 1 mg/ml. TF-1 (A), TF-2 (B), and TNP (C) were analyzed with TEM. To see morphological characteristics of the nanomaterials when they are dispersed in cell culture media, 1 mg/ml of titanate nanomaterials suspension were further diluted with culture media to a final concentration of 25 µg/ml. TF-1 (D), TF-2 (E), and TNP (F) were visualized using a digital optical microscope.
