1. A method of preparing a bone repair material, comprising:
(1) preparing a dopamine solution by dissolving dopamine hydrochloride in Tris-HCl buffer;
(2) adding β-tricalcium phosphate to the dopamine solution obtained in step (1), and after stirring uniformly, centrifuging, washing and freeze-drying, obtaining β-tricalcium phosphate coated with polydopamine labeled as β-TCP-PDA; and
(3) dispersing the β-TCP-PDA obtained in step (2) into Tollens' reagent, then adding glucose and polyvinylpyrrolidone thereto and stirring evenly to obtain a β-TCP bone repair material loaded with nanosilver particles which is labeled as β-TCP-PDA-Ag, and thereby obtaining the bone repair material.
