Abstract

Gd4O2S:Yb:Tm rare-earth upconversion phosphors have been utilised to monitor the redox behaviour of flavin mononucleotide and report on the turnover of a flavo-protein, (pentaerythritol tetranitrate reductase). The presence of two bands separated by over 300 nm in the UCP emission spectra allows ratiometric signalling of these processes with high sensitivity. [ABSTRACT FROM AUTHOR]

Abstract

An aniline-rhodamine-based ratiometric fluorescent probe (RI) was designed and synthesized. RI, the metal coordinating chromophoric ligand, exhibited high selectivity and sensitivity for Pd2+ ions with a detection limit of 73.8 nM. This method of Pd2+ detection had a 10 min response time.
