Chelation enhanced fluorescence of rhodamine based novel organic nanoparticles for selective detection of mercury ions in aqueous medium and intracellular cell imaging
A novel peptide-based fluorescent chemosensor containing both tryptophan and a dansyl fluorophore has been designed to detect Zn2+ in 100% aqueous solution and living cells via two pathways including fluorescence resonance energy transfer and chelation enhanced fluorescence.
A new diformyl phenol based probe for selective detection of Cu2+in aqueous medium, applicable for cell imaging in Vero cells. Theoretical studies were performed to establish the underlying keto–enol tautomerism and optimization of the Cu2+complex.
A new fluorescent probe based on pyridine Schiff base (2-(pyridine-2-ylmethylene)phenoxyaniline, PMPA) working with PET mechanism and chelation enhanced fluorescence (CHEF) was designed and synthesized for the selective detection of cadmium...
Pyridine-2,6-dicarboxamide based scaffolds with appended naphthyl groups act as fluorescent probes for the selective detection of Pd2+ ions in aqueous medium and have applications as paper-strip sensors, as polystyrene films, and in cell imaging.
A new metal-organic framework (MOF) showed excellent recognition ability towards five toxic oxo-anions viz. arsenate (HAsO42-), phosphate (PO43-), permanganate (MnO4-), chromate (CrO42-) and dichromate (Cr2O72-) in aqueous medium upon irradiation...
A highly selective “ON–OFF” probe for colorimetric and fluorometric sensing of Cu2+in water
