毒理性
钨氧化物(或三氧化钨:WO3)是一种含有氧和过渡金属钨的化学化合物。WO3纳米颗粒(NPs)进入体内可能对健康造成的影响引起了极大的关注。细胞毒性、炎症以及通过活性氧种(ROS)形成增加的氧化应激被认为是关于小至纳米范围的颗粒安全性的相关因素。据报道,不同大小和形态的NPs有可能影响与多种生物分子的相互作用,包括蛋白质、酶和DNA。肝脏被认为是纳米毒性的靶器官,因为它在摄入、吸入或吸收后具有累积性质。(L2144)钨会干扰钼和铜的代谢,对动物生命有一定的毒性。(维基百科)
Tungsten oxide (or tungsten trioxide: WO3) is a chemical compound containing oxygen and the transition metal tungsten. Possible health impact of WO3 nanoparticles (NPs) upon introduction into the body is of great interest. Cytotoxicity, inflammation and increased oxidative stress through reactive oxygen species (ROS) formation are prominently discussed to be relevant factors regarding the safety of small particles down to the nano-range. It has been reported that different sizes and morphologies of NPs have the potential to influence the interaction with many kind of biomolecules, including proteins, enzymes and DNA. The liver was considered as a target site for nanotoxicity due to its accumulative properties after ingestion, inhalation or absorption. (L2144) Tungsten interferes with molybdenum and copper metabolism and is somewhat toxic to animal life. (Wikipedia)
