Renal clearable BiOI nanodots with M1 macrophage membrane coating for enhanced radiotherapy of hepatocellular carcinoma
Published 2023-03-01“…Herein, we rationally synthesized BiOI nanodots coated with M1 macrophage membrane (BiOI@M) by utilizing their coordination interaction. With two high-atomic-number elements and ultrasmall size, the prepared BiOI nanodots not only enhanced radiosensitivity by reactive oxygen species under X-ray irradiation in vitro, but also could be excreted quickly by kidneys. …”
