ABSTRACT
In recent years, it is a hot spot of research on detecting heavy metals such as Pb (II), Cu (II), and Hg (II) and harmful element As (III) based on novel fluorescence probe quantum dots (QDs). This review introduced the preponderance optical properties and advantages of QDs. In addition, the principles of fluorescence quenching concerning ion complexing reaction, electron transfer, fluorescence resonance energy transfer and others, fluorescence enhancement and methods combined with rolling circle amplification of DNA, redshift of emission wavelength, fluorescence ratio and others were presented. Finally, the paper summarized the applications and took prospect to provide the basis for the detections of heavy metals and harmful elements in Chinese materia medica based on fluorescence probes QDs.
