Recent progress on synthetic and protein-based genetically encoded sensors for fluorimetric Cu(i) recognition: binding and reaction-based approaches

Abstract

Due to an extensive range of biological significance and applications, the development of different fluorescent probes for Cu ions has been an active area of research over the past 10...

An Indole‐based Chromofluorogenic Probe for Detection of Trivalent Al3+, Ga3+, In3+ and Fe3+ Ions

“…As a part of our ongoing research in the design and development of new optical probes, [58][59][60][61][62][63][64][65] herein we present an easily synthesizable indole-based chromofluorogenic Schiff base probe (InNS; Figure 1(a)) for recognition of trivalent Al 3 + , Ga 3 + , In 3 + and Fe 3 + ions over other mono-and bivalent cationic species. In this probe, the indole moiety acted as a fluorophore while a combination of both hard (imine-N) and soft (À SÀ ) donor sites served as the metal ion recognition unit.…”
