A novel system for Fe3+ ion detection based on fluorescence resonance energy transfer

Detection of Al3+ and Fe3+ Ions with Phthalocyanine‐Merocyanine 540 Dye‐Based Fluorescence Resonance Energy Transfer

“…The two metal ions have responded to this sensor system based on FRET between PC and MC540. For FRET‐based Fe 3+ determination, limit of detection (LOD) value is generally at the level of uM rarely nM recent studies in the literature 23–29 . We obtained a very low LOD value for Fe 3+ ion compared to the literature.…”

“…For FRET-based Fe 3+ determination, limit of detection (LOD) value is generally at the level of uM rarely nM recent studies in the literature. [23][24][25][26][27][28][29] We obtained a very low LOD value for Fe 3+ ion compared to the literature. As well as, the most common Fe 3+ and Al 3+ ions in the ecosystem were able to be detected with high selectivity in aqueous media.…”

Pyronin B‐Graphene Oxide‐Based Turn‐On Fluorescent Sensors for Fe3+ in an Aqueous Medium: Synthesis and Living Cell Application

“…The selectivity of the PyB–GO system are evaluated by adding of various metal ions (Ag + , K + , Ba 2+ , Cu 2+ , Co 2+ , Mg 2+ , Hg 2+ , Fe 3+ , Cr 3+ , Fe 2+ and Zn 2+ ) on the fluorescence response of the fluorescent probes as presented in Figure and Figure . For this purpose, the 3 s/k equation was used, in which s is the standard deviation of blank, k is the slope of the fit line in the fluorescence titration experiment . The limit of detection (LOD) is calculated as 0.99 μM (Table ), which meets the sensitive and fast detection requirement of Fe 3+ ions.…”

A Dendrimer‐Based Electropolymerized Microporous Film: Multifunctional, Reversible, and Highly Sensitive Fluorescent Probe

“…This suggests that an efficient Förster resonant energy transfer (FRET) takes place in PYTPAG2 from surface groups to core. As we know that Fe 3+ has a special chelation capability with “N” atoms over other metal ions because of its more empty “d” shell electronic structure and there are so many “N” atoms in PYTPAG2, so when the “N” atoms of the surface groups cheat with Fe 3+ , the FRET from surface groups to core is disturbed resulting in the remarkable fluorescence quenching …”
