Title:
PREPARATION OF METAL NANOCLUSTER WRAPPED WITH SERICIN PROTEIN AND FLUORESCENCE PROBE
Document Type and Number:
WIPO Patent Application WO/2020/147753
Kind Code:
A1
Abstract:
A preparation method for a metal nanocluster wrapped with sericin protein, comprising the following steps of: uniformly mixing an aqueous solution of a metal nanoparticle precursor and an aqueous solution of sericin protein, then dropwise adding an aqueous solution of alkali to adjust a pH value of the solution to 11-13, performing reaction in absence of light, and after the reaction is completed, obtaining a solution of the metal nanocluster wrapped with the sericin protein. Moreover, a metal nanocluster is prepared by using the method. The metal nanocluster has good selectivity and sensitivity for different metal ions.
