A dual-mode signaling response of a AuNP-fluorescein based probe for specific detection of thiourea.


By employing fluorescein and AuNPs as energy donors and acceptors, respectively, a novel fluorescence resonance energy transfer (FRET)-based dual-mode sensor for selective recognition and quantitative detection of thiourea was designed and constructed in this study for the first time. Herein, it is demonstrated that fluorescein could be adsorbed on the… (More)
