A novel and convenient one-pot but two-step synthesis of fluorescent gold nanoclusters, incorporating glutathione (GSH) and 11-mercaptoundecanoic acid (MUA) as the functionalized ligands (i.e. AuNCs@GSH/MUA), is demonstrated. Herein, the mixing of HAuCl4 and GSH in aqueous solution results in the immediate formation of non-fluorescent GSH-Au(+) complexes, and then a class of ∼2.6 nm GSH-coated ...
A simple, rapid, and convenient colorimetric chemosensor of a specific target toward the end user is still required for on-site detection and real-time monitoring applications. In this study, we developed a rapid in situ colorimetric assay for cobalt detection using the naked eye. Interestingly, a yellow to light orange visual color transition was observed within 3 s when a Chrysoidine G (CG) c...
Fluorescent chemosensorssmolecules that change their fluorescence in response to substrate bindingsoffer an extremely sensitive optical method for the real-time monitoring of molecular interactions.1 Such chemosensors are finding increased use in fields as diverse as biology, medical analysis, and environmental monitoring.1a,6 The majority of fluorescent chemosensors operate by one of three mec...
