Characterization of silica nanoparticles (SiNPs).

Notes: (A) Transmission electron microscopy image of SiNPs in deionized water. (B) Transmission electron microscopy image of SiNPs in serum-free Dulbecco’s Modified Eagle’s Medium. (C) Thermogravimetric analysis of SiNPs. (D) Size distribution of SiNPs calculated using ImageJ Software. SiNPs in both water and medium dispersed stably and had a spherical morphology of 43 nm in size on average as measured using ImageJ software.
