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.
