Question - What factors influence the potential for toxicity of nanoparticles?
Answer - According to NIOSH, “Studies have indicated that low solubility nanoparticles are more toxic than larger particles on a mass for mass basis. There are strong indications that particle surface area and surface chemistry are responsible for observed responses in cell cultures and animals. Studies suggests that some nanoparticles can move from the respiratory system to other organs. Research is continuing to understand how these unique properties may lead to specific health effects.” (https://www.cdc.gov/niosh/topics/nanotech/; accessed July 2018)
