Abstract: A colorimetric and fluorescence turn-on dual-signal assay was developed for the determination of ascorbic acid (AA). Because the ultraviolet absorption of the oxidized 3,3',5,5'-tetramethylbenzidine (oxTMB) overlapped with the fluorescence emission of glutathione stabilized Au nanoclusters… read more here.

Abstract: Abstract 2-Hydroxy-5-methyl-3-((quinolin-6-ylimino)methyl)benzaldehyde (HL) has been found to be a ratiometric fluorescent chemosensor for pH. It has been synthesized by Schiff-base condensation reaction between 4-methyl-2,6-diformylphenol and 6-aminoquinoline in 1:1 ratio in methanol and characterized by various… read more here.
