| titleOfInvention | One-step method for synthesizing DNA functionalized Zn doped CdTe quantum dot |
| abstract | The invention belongs to the fields of nanometer materials and biomedical analysis chemistry, and particularly relates to a one-step method for synthesizing DNA functionalized Zn doped CdTe quantum dots. The quantum dot probe is prepared by connecting phosphorylated DNA to surface of quantum dot by coordination of sulfur and cadmium, and quantum dot surface can be connected with 1-2 DNA fragments. The preparation method is as below: in a synthesis process of quantum dots, phosphorylated DNA is added to obtain the DNA functionalized quantum dot probe through a one-step reaction. The probe can be used as a bifunctional nanometer material, has high fluorescence quantum yield, good biocompatibility and good dispersion, and can be used for detection of DNA fragment and protein, cell identification and tumor targeting. Compared with a traditional DNA marked quantum dot method, the preparation method provided by the invention is simple and low-cost, does not require expensive preparation facilities, can be accomplished in general chemistry laboratory, and can be widely used in fields of biological detection, cellular imaging, target tracing and disease diagnosis, etc. |
