Summary: The abuse of pesticides has resulted in the presence of residues in soil and drinking water, posing risks to the food chain and human health. There is an urgent need for monitoring and developing detection methods for pesticide residues. This study introduces a one-pot prepared CdS fluorescent quantum dots (QDs) and explores their application in detecting organic pesticides. The QDs show sensitive and selective detection of three different pesticides, and a smartphone is utilized for qualitative and quantitative analysis of one of the pesticides.

Summary: The endothelin signaling system, consisting of endothelin peptides and their corresponding receptors, plays important roles in vascular tone regulation, inflammation, proliferation, and water homeostasis. In pathological conditions, it is involved in cardiovascular diseases, cancer progression, and renal disease. Antagonists of endothelin receptors have been developed for over 30 years and preclinical studies have used in vivo imaging to assess their contributions in various diseases. In this study, two new fluorescence probes targeting the ETBR receptor were developed and evaluated in a breast cancer model.

Summary: This research reviews the performance differences between seawater-mixed and conventional concretes, highlighting the chloride-induced hydration mechanism in seawater. While additives and curing conditions can mitigate some of the negative effects, the unstable chloride binding ability in cement hydrates limits the practical application of seawater in concrete for the risk of rebar corrosion. Recommendations are made for future applications in the construction industry while emphasizing the importance of carefully considering the trade-offs associated with using seawater in concrete.

Summary: Rapid industrialization and manufacturing expansion have led to heavy metal pollution, a critical environmental issue faced by the global population. Conventional detection methods have limitations, leading to the development of novel nanosensors. Carbon dots (CDs) have been proposed as an alternative for accurate detection of heavy metal ions in water systems. This review discusses successful examples of using CDs for metal ion detection, strategies to enhance their photoluminescence properties, and challenges for further research.

Summary: In this study, ratiometric, fluorescent pH-sensitive nanosensors were fabricated and utilized for real-time quantification of fast-dynamic, interfacial pH changes in electrochemical processes. Electrochemically coupled laser scanning confocal microscope (EC-LSCM) was used to detect spatio-temporal pH changes during the electrocoagulation treatment of oil-sands-produced water. The operando visualization of interfacial pH provided new insights into electrode processes and offered a powerful pathway for optimizing operating conditions and enhancing the efficiency of various electrochemical processes.

Summary: A new spectrofluorimetric method based on nitrogen-doped carbon quantum dots (N-CQDs) fluorescent probes was proposed for the determination of larotrectinib. The method is simple, involves no pre-treatment steps or complicated techniques, and showed sufficient sensitivity for the analysis of the drug. The synthesized N-CQDs exhibited high fluorescence intensity, allowing for the selective quenching and sensitive determination of larotrectinib.

Summary: In this study, we synthesized nanometric B2O3 nanodisks that exhibited intense fluorescence in the visible range. These boron-based nanomaterials were water-dispersible and nontoxic, with a highly crystalline structure. In addition, their bright blue photoluminescence showed high sensitivity and selectivity towards Ni2+ ions in solution, even at extremely low concentrations in the picomolar range. These findings suggest that the B2O3 nanodisks could serve as ultrasensitive multi-messenger Ni2+ nanosensors.
