The present invention relates to a nanomaterial for preventing tumor bone metastasis, a preparation method therefor, and use thereof. The present invention has discovered a spatiotemporal coupling interaction between tumor cells and osteoclasts, and provides a tumor-bone initial metastasis behavior-targeting strategy which can accurately prevent tumor metastasis on the basis of the source, and can avoid drug resistance and biochemical drug resistance. On this basis, the present invention designs a physical killing nanomaterial targeting tumor-osteoclast conjugates, the nanomaterial being a bone targeting group-modified nanovesicle encapsulating a carbonate compound and a phosphate compound. The nanomaterial can be effectively concentrated in bone tissue; when tumor cells are activated, the acid secretion function of tumor-related osteoclasts in nearby tumor-osteoclast conjugates which are in contact with the tumor cells triggers the carbonate compound to generate carbon dioxide gas and promotes the release of the phosphate compound, which forms calcium phosphate crystals with calcium ions so as to kill nearby tumor cells, thus achieving a specific very-early tumor metastasis inhibition effect.
