“…Hg 2+ can eventually reach the human body through the food chain due to its high bioaccumulation effect, even trace levels of Hg 2+ can cause irreversible damage to the human liver, kidney, endocrine system, and nervous system . Considering the toxic effects of Hg 2+ , strict standards were established by the United States Environmental Protection Agency (EPA) and World Health Organization (WHO), which stipulate the maximum allowable Hg 2+ level in drinking water is 10 nM and 30 nM, respectively. , Therefore, it is urgent to explore highly specific, efficient, cost-effective, and sensitive approaches for the determination of Hg 2+ in practical scenarios.…”

Determination of Hg 2+ is crucial as its high toxicity poses a potential serious threat to food and the environment. Therefore, it is urgent to explore a portable, cost-effective, and visual approach to monitor Hg 2+ . Herein, ratiometric-constructed dual-emissive carbon dots (P-R-CDs) with dual emissions at 440 and 575 nm were fabricated by blue CDs and orange CDs for visual quantitative detection of Hg 2+ . The vivid colorimetric sensing can be achieved by quantitative quenching blue emission with Hg 2+ and relative stable orange emission. Consecutive fluorescent color transformation with elimination of blue emission by Hg 2+ embodied visible distinguishable determination of Hg 2+ , with a detection limit of 2.9 nM. Furthermore, a smartphonesupported visual sensing platform was established for the determination of Hg 2+ by capturing and identifying the RGB value of the variation precisely. The smartphone assistant detection greatly promoted the effectiveness of detection and provided promising on-site application in real samples. The recoveries in real water and food samples revealed the excellent environmental tolerance of P-R-CDs, which represented a prospective application utility for quantitative monitoring of Hg 2+ in food and the environment.

In this work a new, simple, fast, and efficient electrochemical approach for the determination of inorganic mercury (Hg2+) using the differential pulse anodic stripping voltammetry (DPASV) technique was presented. This is achieved by modifying the surface of a carbon paste electrode by electropolymerization of Eriochrome blue black R. First, the behavior of Hg2+ on the modified electrode is studied by cyclic voltammetry and electrochemical impedance spectroscopy, to evaluate performance and understand the phenomena that take place on its surface. DPASV is then used to optimize the sensor in HClO4 medium. After optimization, a linear calibration graph was obtained in the concentration range of 1x10-9 to 9x10-9 mol.L-1 with correlation coefficient R2= 0.9975%, the limit of detection (LOD) and the limit of quantification (LOQ) obtained are respectively 3.23x10-10 mol.L-1 and 1.07x10-9 mol.L-1. The relative standard deviation (RSD) for 7 measurements is 3.07%, which proves that this sensor is reproducible. Finally, this method has been successfully applied in real samples of water and the results obtained are satisfactory because the recovery rates of Hg2+ vary from 99.2 to 100.1%.

Antibiotics play an essential role in the treatment of various diseases. However, the overuse of antibiotics has led to the pollution of water bodies and food safety, affecting human health. Herein, we report a dual-emission MOF-based flexible sensor for the detection of antibiotics in water, which was prepared by first encapsulating rhodamine B (RhB) by a zeolite imidazolium ester skeleton (ZIF-8) and then blending it with polyvinylidene difluoride (PVDF). The luminescent properties, structural tunability, and flexible porosity of the MOF-based composites were combined with the processability and flexibility of polymers to prepare luminescent membranes. The sensor is capable of dual-emission ratiometric fluorescence sensing of nitrofurantoin (NFT) and oxytetracycline (OTC), exhibiting sensitive detection of fluorescence burst and fluorescence enhancement, respectively, with detection limits of 0.012 μM and 8.9 nM. With the advantages of visual detection, high sensitivity, short detection time, and simplicity, the highly sensitive ratiometric fluorescent flexible sensor has great potential for detecting antibiotics in an aqueous environment. It will further stimulate interest in luminescent MOF-based mixed matrix membranes and their sensing applications.
