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.
