摘要: 纳米材料作为一种新兴材料,在疾病诊断与治疗中拥有极大的应用潜力。为平衡纳米材料的生物活性和生物毒性之间的关系,清楚了解纳米材料在体内的清除机制和清除速率至关重要。其中,肾脏,作为人体重要的清除器官,直接影响纳米材料从血液清除到尿液的速率,进而影响其在生物体内的血液循环、肿瘤靶向效率和体内滞留等系列问题,最终影响其临床应用。基于近年来已报道的关于纳米材料与肾脏相互作用的诸多研究,本文系统介绍了肾脏结构、纳米材料在肾脏中的传输机制、理化性质对其肾脏清除效率的影响以及纳米材料在肾脏疾病诊疗中的应用。本文有望为精准纳米医学的发展以及纳米材料未来的临床转化起到促进作用。

Abstract: Nanomaterials, as emerging materials, show great promise for the detection, diagnosis and treatment of diseases. Fully understanding their elimination pathway and clearance efficiency is important to better balance the bioactivity and biotoxicity of nanomaterials. Kidneys, as a major organ, play a key role in the clearance of nanomaterials from blood to urine. The clearance rate of nanomaterials in the kidneys directly affects their blood circulation, retention in the body and tumor targeting efficiency as well as final clinical applications. Based on current understanding of nano-bio interactions of nanomaterials in the kidneys, in this review, we introduced the kidney structure and elimination mechanism of nanomaterials in the kidneys. Then, how the physicochemical properties of nanomaterials affect their renal clearance efficiency are summarized. Finally, their applications in the kidney disease detection and treatment are presented. The basic understanding of nano-bio interactions of nanomaterials in the kidneys would promote the development of precise nanomedicine and their future clinical translation.
