Review Ultra-small fluorescent metal nanoclusters: Synthesis and biological applications Li Shang, Shaojun Dong and G. Ulrich Nienhaus  Abstract Recent advances in nanotechnology have given rise to a new class of fluorescent labels, fluorescent metal nanoclusters, e.g., Au and Ag. These nanoclusters are of significant interest because they provide the missing link between atomic and nanoparticle behavior in metals. Composed of a few to a hundred atoms, their sizes are comparable to the Fermi wavelength of electrons, resulting in molecule-like properties including discrete electronic states and size-dependent fluorescence. Fluorescent metal nanoclusters have an attractive set of features, such as ultrasmall size, good biocompatibility and excellent photostability, making them ideal fluorescent labels for biological applications. In this review, we summarize synthesis strategies of water-soluble fluorescent metal nanoclusters and their optical properties, highlight recent advances in their application for ultrasensitive biological detection and fluorescent biological imaging, and finally discuss current challenges for their potential biomedical applications. Graphical abstract Highlights ► Fluorescent metal nanoclusters are novel luminescent nanomaterials with ultrasmall dimensions. ► Fluorescent metal nanoclusters have been synthesized with various biocompatible coatings. ► Recent advances have demonstrated the potential of metal nanoclusters as luminescent probes for biological applications.

楼主在 Sensitive turn-on fluorescent detection of cyanide based on the dissolution of fluorophore functionalized gold nanoparticles 提到了荧光内滤效应····Secondly, the absorbance of RB-Au NPs at both the excitation and emission wavelength is substantial (see Figure 2 in the text), which can also cause the fluorescence decrease. Thus the contribution of inner filter effect (IFE) to the observed fluorescence quenching can not be neglected. 我比较愚钝，楼主可否简述一下？荧光内滤效应是什么意思? |
