We work on the "full chain" innovative research on the preparation of fluorescent nanomaterials, surface modification, biological functionalization, biomarkers and dynamic imaging, and focuse on the bioprobes and biomedical dynamic imaging and analysis of quantum dots. After more than 10 years of hard work, we have developed the "living cell synthesis" and "quasi biosynthesis" of quantum do...

Refer to the fluorescence semiconductor nanocrystals less than or close to the mean radius (≲) the exciton Bohr radius of quasi zero dimension (size: 1-20 nm), Quantum dots (QDs) are developed in the seventy s of the 20th century, which have unique fluorescent properties.Compared with traditional fluorescent proteins and organic fluorescent dyes, QDs have significant advantages. Therefore, QDs are widely used in the field of cell biology, biochemistry, immunology and other subjects for labeling and imaging.

It is of great significance to study the mechanism of virus infection for the prevention and early diagnosis and treatment of viral diseases.The process of virus infection into host cells is quite complex, often involving multiple steps, and involves complex interactions between viruses and various cellular structures.Therefore, there is an urgent need for a technology to study virus infection in host cells in real time and in situ, and single particle tracing technology is a powerful tool to study the dynamic process of biological events, which can w...

Infectious diseases have always been a major threat to human health.For highly infectious pathogens, rapid, sensitive and reliable detection methods are not only conducive to the rapid diagnosis and timely treatment of diseases, but also can be infected with infectious diseases, especially those infected with virulent viruses, timely and effective isolation, can greatly reduce the infection rate, improve the survival rate. In recent years, immunochromatography has become the most promising rapid detection method because of its convenience, speed and e...
