1. a kind of preparation method of fluorescence gold nano clusters with stable chicken ovalbumin is it is characterised in that comprise the following steps:

  • (1) weigh chicken egg white, deionized water dissolving is configured to chicken egg white solution, and the chicken egg white being configured to is moltenThe concentration of liquid is 0.5-10mg/ml;

    (2) chlorauric acid solution taking concentration to be 1mm-100mm, is added in above-mentioned chicken egg white solution, obtains the clear egg of ovum gallinaceumWhite with gold chloride mixed solution, gold chloride is 1;

    1-1;

    10 with the mol ratio of chicken egg white;

    (3) naoh or naoh aqueous solution, regulating step (2) gained chicken egg white and gold chloride mixed solution to ph are utilized11.5-13;

    (4) step (3) resulting solution is fallen in round-bottomed flask, be placed in microwave reactor, react 15s-120s;

    (5) pour out the solution after microwave reaction, naturally cool to the gold nanoclusters that room temperature obtains glowing.
