A drug carrier nanoparticle has been synthesized that can specifically target the proximal tubules of the kidneys. The nanoparticles accumulate in the kidneys to a greater extent than other organs (e.g., up to 3 or more times greater in the kidney than any other organ). They can encapsulate many classes of drug molecules. The nanoparticles are biodegradable and release the drug as they degrade. The particles can sustainably release a drug within the kidneys for up to two months. The nanoparticles are useful for the treatment of diseases that affect the proximal tubules, such as heart failure, liver cirrhosis, hypertension, and renal failure; the study of relative blood flow to the renal cortex and medulla; and delivery of agents to treat gout.

0001 The present invention relates to a nanomaterial for preventing tumor bone metastasis, a preparation method therefore and use thereof. The present invention discovers a spatiotemporal coupling interaction between tumor cells and osteoclasts, and provides a tumor-bone initial metastasis behavior-targeting strategy, which may accurately prevent tumor metastasis based on the source, and may avoid drug resistance and biochemical resistance. Based on this, the present invention designs a nanomaterial for physical killing targeting tumor-osteoclast conjugates, and the nanomaterial is a bone-targeting group-modified nanovesicle encapsulating a carbonate compound and a phosphate compound. The nanomaterial can be effectively enriched in bone tissue; when the tumor cells are activated, an acid secretion function of tumor-related osteoclasts in the tumor-osteoclast conjugates in close contact triggers the carbonate compound to generate a carbon dioxide gas, and promotes the phosphate compound to release to form calcium phosphate crystals with a calcium ion, so as to kill nearby tumor cells, thereby achieving a specific very-early tumor metastasis inhibition effect.
