Abstract:
With the continuous research on nanotechnology, nanosensors for the detection of various biomolecular have emerged one after another. As one of the main nanosensors, quantum dots have unique optical and particle properties, and quantum dot probes for pathogen detection have been widely used. The emerging fluorescent biomarkers, quantum dot probes, have unparalleled advantages over other fluorescent probes, such as strong fluorescence signal, good photostability, long fluorescence lifetime, and large Stokes shift. They can detect the target simply, quickly, sensitively and specifically. This article provides an overview of the basic properties of quantum dots and the application foundation of quantum dot probes as detection sensors. We focus on the types and preparation method of quantum dot probes, as well as their applications in pathogen detection in recent years. Finally, the application precautions of quantum dot probes as detection sensors were summarized, and the application prospects of quantum dot probes in the field of pathogen detection were also discussed.
