A kind of preparation method of the bimetallic organic backbone antimicrobial nano particle with photo-thermal effect, comprises the following steps：S1, the potassium ferricyanide and anhydrous zinc chloride mixed with deionized water respectively, obtain solution A, B solution respectively, then solution A, B solution are mixed evenly, it is standby；After being stirred in S2, the solution for obtaining polyvinylpyrrolidone addition step S1, hydrochloric acid is added, and stirring makes it fully dissolve, then stand aging precipitation；S3, material that step S2 is obtained centrifuged into reaction mixture to obtain blue precipitate, and centrifuged, washed respectively with ethanol and deionized water, to obtain precipitated product；S4, product that step S3 is obtained is placed in refrigerator be freeze-dried.Its advantage is：Use the nano cubic particle of mixing time, controllably synthesis uniform particle diameter in precipitation aging method control building-up process；Micro zinc ion effectively facilitates cell proliferation and differentiation, promotes wound healing, green. |
