纳米颗粒(NPs)具有彻底改变药物递送的潜力,然而,在不需要静脉注射的情况下将其施用到人体仍然是一个重大挑战。在这项研究中,一系列的近红外(NIR)荧光纳米粒子的化学组成,形状,大小和表面电荷系统地变化,并在大鼠模型肺灌注后,其生物分布和消除进行了定量。我们证明,纳米粒子的流体动力学直径(HD)小于34nm和非阳离子表面电荷迅速从肺转移到纵隔淋巴结。HD <6nm的NP可以从肺快速运输到淋巴结和血流,然后随后被肾脏清除。我们讨论了这些发现对药物输送,空气污染和致癌作用的重要性。
Nanoparticles (NPs) have the potential to revolutionize drug delivery, however, administering them to the human body without the need for intravenous injection remains a major challenge. In this study, a series of near-infrared (NIR) fluorescent NPs were systematically varied in chemical composition, shape, size, and surface charge, and their biodistribution and elimination were quantified in rat models after lung instillation. We demonstrate that NPs with hydrodynamic diameter (HD) less than ≈ 34 nm and a non-cationic surface charge translocate rapidly from lung to mediastinal lymph nodes. NPs of HD < 6 nm can traffic rapidly from the lungs to lymph nodes and the bloodstream, and then be subsequently cleared by the kidneys. We discuss the importance of these findings to drug delivery, air pollution, and carcinogenesis.
