Luminescent Noble Metal Nanoclusters as an Emerging Optical Probe for Sensor Development

摘要: In the past few years, highly luminescent noble metal nanoclusters (e.g., Au and Ag NCs or Au/Ag in short) have emerged as a class of promising optical probes for construction high-performance sensors because their ultrasmall size (<2 nm), strong luminescence, good photostability, excellent biocompatibility, unique metal-core@ligand-shell structure. this Focus Review, we briefly summarize common syntheses water-soluble highly-luminescent thiolate- protein-protected interesting luminescence properties, highlight recent progress use with an emphasis on mechanisms underlying selectivity, finally discuss approaches to improving sensitivity. The scope works surveyed is confined NCs.
