Figure 1From: A mixture of anatase and rutile TiO2 nanoparticles induces histamine secretion in mast cells TiO 2 NP characterization using DLS and TEM. (A) DLS assessment of TiO2 NP in Hanks' solution revealed a size distribution of ~6 to 100 nm. (B) A representative TEM image of the TiO2 NPs with an average diameter of 60 ± 10 nm (n = 300). (C) A bar graph showing the size distribution of TiO2 NPs based on TEM images (n = 300).Back to article page
