Abstract Flavonols, named as 3-hydroxyl-2-phenyl-1-benzopyran-4-one, are important
natural botanical functional pigments widely distributing in fruits, vegetables, and flowers …

In recent years, there has been an increase in public perception of the detrimental side-
effects of fluoride to human health due to its effects on teeth and bones. Today, there is a …

This paper describes a novel ratiometric fluorescence-based sensor for the detection of
fluoride ion. Yb3+, Er3+, and Tm3+ codoped NaYF4 upconversion nanoparticles (UCNPs) …

A novel bis-BODIPY-based colorimetric and fluorescent sensor (BODIPY-NN) for F− and
CN− recognition with high selectivity and high sensitivity is reported. The designed sensor …

Low cost and in situ fluoride detection by non-experts is important for the determination of
drinking water safety in developing countries. Colour reagents can provide results quickly …

The discussion in this review focuses on the results of synthetic ratiometric fluorescent and
colorimetric probes, which have been applied to sense fluoride anion qualitatively as well as …

Colorimetric sensors have attracted wide scope of attentions due to its fascinating
advantages, like handy, equipment-free and naked eye detections. In this investigation, a …

A conjugated polymer containing the ortho-azonaphthol (o-AN) group was synthesized via
the Suzuki coupling reaction, exhibiting an orange color and red fluorescence in its solution …

A novel colorimetric and ratiometric probe (SH-GA) for the fluoride ion detection was
designed and synthesized from gallic acid. SH-GA exhibited a selective color change from …

The conjugate N, N-dimethyl curcumin analogue fluorophore dye 1 has been synthesized
and its performance as a sensor was demonstrated. As a fluoride and cyanide sensor it …
