Lysozyme-stabilized gold fluorescent cluster: Synthesis and application as Hg2+ sensor
Highly fluorescent gold clusters have been synthesized in basic aqueous solution by using lysozyme as reducing and stabilizing agents. The lysozyme-stabilized gold fluorescent clusters (LsGFC) have an average size of 1 nm and emission ~ 657 nm. The fluorescence could be specifically quenched by Hg 2...

| Zusammenfassung: | Highly fluorescent gold clusters have been synthesized in basic aqueous solution by using lysozyme as reducing and stabilizing agents. The lysozyme-stabilized gold fluorescent clusters (LsGFC) have an average size of 1 nm and emission ~ 657 nm. The fluorescence could be specifically quenched by Hg

, so the LsGFC can be used as a sensor for sensitive and selective Hg
