- In vivo bioimaging technology is a powerful means to detect molecular and cellular events in experimental animals. It is being used more and more widely in medical and biological research fields. It has extremely high detection sensitivity and low cost of experimentation. It can be extremely short. The application of as few animals as possible within the time can accurately obtain the expected experimental results, providing researchers with a wide application space, but the technology still has many limitations, especially the tissue autofluorescence generated during in vivo illumination. Weak tissue permeability under the excitation of broken wave excitation light.

- the nude mouse tumor model is an orthotopic transplantation tumor model, an orthotopic metastatic tumor model, a subcutaneous tumor model, a drug-induced tumor model, a gene mutation tumor model or a spontaneous tumor model.
- the silver and platinum nanoclusters prepared by the invention have small particle size, good permeability, high fluorescence stability, high sensitivity and strong targeting, and can accurately locate the tumor;
- the silver and platinum nanoclusters of the present invention are ultrasonically dispersed and injected, so that the nanoparticles are finer and more uniform, and are more favorable for absorption;
- the invention has the advantages of convenient operation and direct result, and can be used for early detection and diagnosis of tumors, and can also be applied in research on tracking and imaging of living tumors such as deep tumors and large animals, and has potential application value of clinical disease tracking treatment imaging. .
