Fluorine is the 13th most abundant element on Earth, and fluoride is part of our everyday lives, present in our drinking water, beauty products, and naturally present in food and beverages. It is a key element to increase the resistance of the dental enamel to the acidic bacteria attack and prevent dental decay. However, the ingestion of this anion for an extended period of time and in concentrations over the recommended limits can produce mild to severe health issues, called fluorosis, that can produce incorrect dental enamel formation, reduce the functionality of joints and even affect the bone structure. To avoid these terrible effects, it is necessary to control the fluoride levels in drinkable water, particularly in communities without access to safe water networks. To achieve this goal, the first step is to identify safe water sources and provision portable and reliable sensors to these communities. A major step towards safe water accessibility would be the implementation of these sensors by the proper use of new materials and technologies. Here we present an overview of the traditional quantification methodologies and the new ones for fluoride detection and quantification, and the future trends on portable devices for user-friendly on-point measurements.

“…This can be achieved by implementing cost-efficient, portable, and reliable sensors capable of selectively detecting fluoride ions in water, even in minute concentrations. [29] Although a lot of sensing methods have been exploited for quantitative and qualitative assessment of fluoride levels in drinking water, [30][31][32][33][34][35] their real-time usage remains a challenge due to the requirement of trained personnel as well as expensive instrumentation. Nanozyme-based sensing of fluoride in water provides the advantage of naked-eye detection, in the form of color change.…”

Graphitic carbon nitride quantum dots (g‐CNQDs)‐based colorimetric sensors are typically solution‐based and hence incompatible with wearable electronics. Today's competitive technology demands safe and reliable, high‐performance sensors suitable for integration with sophisticated electronics—all at a low cost. Herein, a flexible and reusable solid‐state fluoride ion sensor manufactured by combining the intriguing surface properties of laser‐patterned carbon (LP‐C) with the sensitivity of g‐CNQDs is reported. LP‐C is obtained by direct IR‐laser writing onto polyimide films, and g‐CNQDs are synthesized via a solvent‐free and zero‐waste green process. The hybrid of LP‐C and g‐CNQDs (g‐CNQDs/LP‐C), mimics the natural enzyme horseradish peroxidase and oxidizes the chromogenic substrate 3,3’,5,5’‐tetramethylbenzidine in the presence of H2O2 in acidic media. The highly selective and user‐friendly nanozyme sensors feature a lower limit of detection of 0.568 ± 0.006 × 10−6 m (23.8 ± 1.5 µg L−1) with linearity in the range of 0.5 × 10−6 to 100 × 10−6 m. A sensing mechanism based on the electronic transitions of g‐CNQDs and LP‐C, the two variants of nitrogen‐containing carbon used in this work, is established. Finally, the device is tested for fluoride ion sensing in natural water samples collected from the Uhl river in Mandi, India.
