【摘要】 纳米材料是"21世纪最有前途的材料",以其优良的性能广泛应用于许多领域,随之以多种形式释放到环境中。目前,关于纳米材料的安全性还没有明确的论断。本文介绍了四膜虫在纳米材料生物效应研究中的优势,重点论述了金属纳米材料、非金属纳米材料对四膜虫的生物效应以及毒性机制的研究状况,并对今后纳米材料生物毒性效应研究提供了建设性的方法及意见。更多还原

【Abstract】 Nanomaterials, which are widely used in many fields owing to their excellent properties have been recognized as "the most promising materials of 21 st Century", and then released into the environment in various forms.At present, safety of nanomaterials has not been clearly determined. Advantages of Tetrahymena in the study of biological effects of nanomaterials, and biotoxicity and toxicological mechanisms of metal nanomaterials and non-metallic nanomaterials to Tetrahymena have been discussed in this paper. Additionally, constructive methods and opinions on the future biological toxicity of nanomaterials research were provided.更多还原
