A Sensitive “Turn-off” Fluorescent Chemosensor for Hg(II) Detection based on a Vanillin-derived N-phenylpyrazoline
Even in small quantities, Hg(II) is one of the most dangerous heavy metals because of its harmful effects on human health. Therefore, Hg(II) monitoring in environmental samples is essential. In this study, vanillin was chemically modified to create new fluorescent chemosensing agents for Hg(II) ions. Vanillin was modif...

TiO2 preconcentration integrated with hydride generation-colorimetric system for the rapid and selective detection of Se(IV).
Selenium (Se) is an essential trace element for humans and the determination of Se(IV) in daily samples is of great significance. A low-cost, easy-used hydride generation-fluorescence colorimetric method was developed for the rapid and selective detection of Se(IV) using a silver-based metal-organic framework (Ag-PMDA)...

CuCo alloy-embedded carbon nanocages for simultaneous biosensing of Hg2+ and Cd2+ in environmental water.
Mercury ions (Hg2+) and cadmium ions (Cd2+) are highly toxic heavy metals that can easily accumulate in the food chain and pose serious threats to the environment. However, achieving sensitive and efficient identification and determination of trace Hg2+ and Cd2+ remain a major challenge in real water environment. In th...

Design and fabrication of a preconcentration-free Mg-doped hydroxyapatite based electrochemical sensor for simultaneous determination of cadmium, lead, and mercury in seafood and plant-derived foods.
Heavy metal contamination in certain food remains a major public health concern due to the persistence, bioaccumulation, and toxicity of cadmium, lead, and mercury. In this study, we report the design and fabrication of a preconcentration-free electrochemical sensor based on magnesium-doped hydroxyapatite (Mg-HAP) nano...

Dual-phase formaldehyde detection via catalyst-triggered AIE in metal-coordinated supramolecular polymers.
It is essential to develop a simple method for detecting formaldehyde (FA) because of its harmful effects on human health. Herein, we present a novel metal-coordinated supramolecular polymer chemosensor utilizing a complex between the tetraphenylethylene (TPE) derivative (T4J) and Cu2+ for FA detection in both gaseous...

Preparation of an aptamer-based photoelectrochemical sensor for sequential detection of both mercury and glutathione in commercial skin lightening cosmetics.
Glutathione (GSH) and Hg2+ both possess skin-lightening effects, but GSH is a beneficial component while Hg2+ poses significant health risks to humans. Accurate quantification of both GSH and Hg2+ is crucial for distinguishing the quality of commercial skin lightening cosmetics. In this study, the In2S3-Ti3C2 photoelec...
