| titleOfInvention | Silver sulfide quantum dot-chitosan nanometer complex preparation method |
| abstract | The present invention relates to a silver sulfide quantum dot-chitosan nanometer complex preparation method, which comprises: 1, dissolving a certain amount of chitosan or a derivative thereof in deionized water at a room temperature to prepare a chitosan aqueous solution with a concentration of 1-20 mg/mL or a chitosan derivative aqueous solution with a concentration of 1-20 mg/mL; 2, under a room temperature stirring condition, sequentially adding a chelating agent and a water soluble silver salt to the chitosan aqueous solution or the chitosan derivative aqueous solution, and carrying out a stirring reaction for 5-20 min; and 3, adding an alkali metal sulfide and a carboxyl compound to the product obtained from the step 2, carrying out a stirring reaction for 5-20 h, carrying out water dialysis and centrifugation on the obtained reaction product, washing sequentially by using absolute methanol and diethyl ether, and carrying out vacuum drying at a room temperature to obtain the silver sulfide quantum dot-chitosan nanometer complex. Compared with the nanometer complex in the prior art, the nanometer complex of the present invention has the following characteristics that: a nanometer complex with a near-infrared fluorescence imaging function is prepared by using a simple and easy-performing method, can be used for biological fluorescence imaging or as a fluorescent probe, and has characteristics of good biocompatibility, no physiological toxicity, and wide application prospects in biomedical fields. |
