碳纳米管(CNTs)已经引起了纳米界和其他领域的极大兴趣。然而,碳纳米管的生物医学应用引起了人们的严重关注,其在体内的未知后果,其中的药代动力学,代谢和毒性的信息是必不可少的。本文从生物医学的角度综述了碳纳米管的最新研究进展。这些信息表明,表面化学是至关重要的,在调节碳纳米管的体内行为。在众多的功能化方法中,聚乙二醇修饰是提高碳纳米管药代动力学和生物相容性的最有效的方法。讨论了药物动力学、代谢和毒性信息对碳纳米管生物医学应用的指导作用。
Carbon nanotubes (CNTs) have attracted great interest of the nano community and beyond. However, the biomedical applications of CNTs arouse serious concerns for their unknown in vivo consequence, in which the information of pharmacokinetics, metabolism and toxicity of CNTs is essential. In this review, we summarize the updated data of CNTs from the biomedical view. The information shows that surface chemistry is crucial in regulating the in vivo behaviors of CNTs. Among the functionalization methods, PEGylation is the most efficient one to improve the pharmacokinetics and biocompatibility of CNTs. The guiding effects of the pharmacokinetics, metabolism and toxicity information on the biomedical applications of CNTs are discussed.
