纳米银通过结合RNA聚合酶抑制红系前体细胞RNA的转录由于其广谱的抗菌活性,纳米银在日常生活和医药卫生中得到广泛的应用.纳米银的大量生产和使用将导致其在生产、运输、使用和排放等环节释放入环境,其潜在的环境与健康风险已日益受到关注.研究发现,纳米银可以引发呼吸系统(肺)、消化系统(肝脏)、神经系统(神经元)和生殖系统的组织损伤.然而,目前对纳米银毒性效应的分子作用机制尚待深入研究. Nanosilver inhibits RNA transcription of erythroid precursors by binding RNA polymerase Due to its broad spectrum of antibacterial activity, nanosilver has been widely used in daily life and medical and health cares.The mass production and use of nanosilver will lead to its production in the production , Transport, use, and release into the environment, potential environmental and health risks have attracted increasing attention.The study found that nano-silver can trigger the respiratory system (lung), digestive system (liver), nervous system However, the current molecular mechanism of the toxic effects of nano silver remains to be further explored.
