自2000年以来,已陆续有科学家针对纳米微粒对人体健康的研究发表,指出纳米微粒的确影响人体器官,尤其是对肺脏及肝脏系统影响更为显著。有实验证明纳米颗粒的粒径越小,产生的毒性效应可能就越大。对超微粒子的毒性看法不一,也有报道表明小鼠气管注入纳米硅胶(14 nm)24 h内引发 Since 2000, scientists have successively published research on human health of nanoparticles, pointing out that nanoparticles affect human organs in particular, especially on the lung and liver systems. Experiments have shown that the smaller the particle size of nanoparticles, the greater the toxic effects may be generated. Toxicity on the ultra-particles of different opinions, there are also reports of mouse tracheal injection of nano silica gel (14 nm) within 24 h
