Recognition of fluoride anions at low ppm level inside living cells and from fluorosis affected tooth and saliva samples

A simple Schiff base chemosensor 2-((2-(2,4-dinitro phenyl)hydrazono)methyl)-4-nitrophenol ( L ) has been developed as a colorimetric and fluorimetric ‘ turn on ’ sensor for fluoride (F − ). F − recognition at ppm levels from mouth rinses and a toothpaste water solution has been successful. Signific...

Summary:A simple Schiff base chemosensor 2-((2-(2,4-dinitro phenyl)hydrazono)methyl)-4-nitrophenol ( L ) has been developed as a colorimetric and fluorimetric ‘ turn on ’ sensor for fluoride (F − ). F − recognition at ppm levels from mouth rinses and a toothpaste water solution has been successful. Significantly, L can detect F − from fluorosis affected tooth and saliva samples by similar colorimetric changes. A test kit for F − detection from a DMSO–water (1 : 1) mixture is also engineered. Intracellular F − from pollen grains of Techoma stans and Candida albicans (a diploid fungus), grown in 10 −6 (M) F − contaminated water has been successfully detected under a fluorescence microscope.
