“…The vancomycin stabilized gold nanoclusters (Van-AuNCs) were designed and synthesized by Yu et al for detection of Fe 3+ in tap water, lake water, river water, and sea water as one of its application in environmental sample analysis [ 66 ]. Chitosan-functionalized gold nanoclusters (AuNCs@Chi) were produced and developed for the use as a detecting material of hydrogen sulfide (H 2 S) employing Förster resonance energy transfer (FRET) mechanism [ 67 ].…”

Gold nanoclusters (AuNCs) have been extensively applied as a fluorescent probe for biomedical applications in imaging, detection, and therapy due to their unique chemical and physical properties. Fluorescent probes of AuNCs have exhibited high compatibility, superior photostablility, and excellent water solubility which resulted in remarkable biomedical applications for long-term imaging, high-sensitivity detection, and target-specific treatment. Recently, great efforts have been made in the developments of AuNCs as the fluorescent probes for various biomedical applications. In this review, we have collected fluorescent AuNCs prepared by different ligands, including small molecules, polymers, and biomacromolecules, and highlighted current achievements of AuNCs in biomedical applications for imaging, detection, and therapy. According to these advances, we further provided conclusions of present challenges and future perspectives of AuNCs for fundamental investigations and practical biomedical applications.

“…2C displays the UV-vis absorption spectra of AuNCs@DCTX, HAuCl 4 and DCTX, and there is no characteristic surface plasmon resonance absorption peak of gold nanoparticles near 520 nm; this suggests that most of the particles are smaller than 2.5 nm; this is evidence for the existence of AuNCs. 30,36 The quantum yield (F) of AuNCs@DCTX in an aqueous solution is 11.8% at 321 nm, with quinine sulfate (0.1 mol L À1 H 2 SO 4 , F ref ¼ 0.54) as the reference based on the slope method ( Fig. S4 †); this value is higher than those of most of the previously developed thiol-protected AuNCs.…”

“…However, few studies have been focussed on the preparation of antibiotic-based uorescent AuNCs for sensing applications. 30 Cefotaxime sodium (CTX), the third generation of cephalosporin against Gram positive and Gram negative bacteria, 31 contains nitrogen, sulphur and oxygen like many efficient ligands or templates of AuNCs. Interestingly, CTX in an alkaline medium can be entirely degraded into an equal mole of a reducing sulydryl compound (DCTX) in a boiling water bath.…”

Fluorescent gold nanoclusters (AuNCs) have recently emerged as a novel kind of promising fluorescent probes for high-performance sensors and bioimaging because of their ultrasmall size (\3 nm), strong luminescence, good photostability, and excellent biocompatibility. Over the past decade, we have witnessed growing popularity of AuNCs in analytical applications and enormous efforts have been devoted to their development. In this review, we provide an update on recent advances in the development of AuNCs in terms of physicochemical properties, synthesis strategies, and bioapplications. The optical, electrochemical, catalytical, and solvatochromic properties of AuNCs are first summarized, which are followed by different ligands or template-assisted controllable synthetic methods. Afterwards functionalization of AuNCs is described in terms of ligand exchange, bioconjugation, and noncovalent interaction. We then focus on the applications of AuNCs as fluorescent probes for detection of metal ions, inorganic anions, small biomolecules, proteins, nucleic acids, drug molecules, pH, and temperature. We also summarize the usage of metal NCs in cellular and in vivo targeting and imaging. Finally, we conclude with a brief look at the future challenges and prospects of the development of AuNCs.
