"金纳米颗粒-三元量子点"体系用于DNA分子杂交的传感检测的制备研究

In the field of biomedical detection, detection of DNA hybridization has been a hot topic. Gold nanorods (GNRs) have larger specific surface area, better fluorescence resonance energy transfer (FRET) characteristics, and can quench the fluorescence in a certain distance. In addition, the ternary quantum dots have unique fluorescence properties, so it is of great application value to detect DNA hybridization using gold nanorods ternary quantum dots system. At present, there are few reports on the construction of "gold nanorods triple quantum dots" system and the application of this system in the detection of DNA hybridization. The purpose of this project is to construct a "gold nanorod ternary quantum dot" system, and to detect DNA hybridization with this system, which provides a basis for related research?
