Scanning electron microscopy (SEM) analysis and spectrum of size distribution of amorphous silica particles. (A-C) SEM photomicrographs of silica particles used in this study: nSP70 (A), nSP300 (B) and mSP1000 (C). Scale bars: 0.1 mm (A) and 0.5 mm (B and C). (D and E) Size distribution of nSP70 (black), nSP300 (gray) and mSP1000 (dashed line) in water (D) or PBS (E) were measured by a dynamic light scattering method.
