, Silica (SiO2) nanoparticles are being progressively applied in various applications, including cosmetics, food technology, and medical diagnostics. Although crystalline SiO2 is a known carcinogen, the carcinogenicity of SiO2 nanoparticles remains unclear. Here, we assessed the cytotoxic effects and DNA injury induced by exposure to various dosages of SiO2 nanoparticles at 0-2400 mg/mL (0-3200 mg/mL microscale SiO2 as positive control) for 24 h using RAW264.7 cells, followed by methyl tetrazolium (MTT) assay.
