| titleOfInvention | Preparation of composite fluorescent nano probe and detection method of hydrogen peroxide by using composite fluorescent nano probe |
| abstract | The invention discloses a preparation method of a CdSe @ ZnS/AgNCs composite fluorescent nano probe, which comprises the following steps of: mixing the CdSe @ ZnS quantum dots and the nano silver clusters under a certain pH condition to prepare a CdSe @ ZnS/AgNCs composite fluorescent nano probe; after mixing, the concentration of the CdSe @ ZnS quantum dots is 0.032mg/mL, and the concentration of the nano silver clusters is 0.015 mg/mL. The CdSe @ ZnS/AgNCs composite fluorescent nano-probe is constructed by directly mixing CdSe @ ZnS quantum dots and nano-silver clusters, and has the advantage of simple synthesis method. The constructed CdSe @ ZnS/AgNCs composite fluorescent nano probe decomposes silver clusters through hydrogen peroxide oxidation, silver ions are released, the silver ions have a quenching effect on CdSe @ ZnS quantum dot fluorescence, and the high-efficiency detection target of hydrogen peroxide is realized, so that the technical problems of long detection reaction time, slow response and insufficient detection lower limit in the traditional technology are solved. |
