Summary: Fluoride detection is crucial for environmental monitoring and disease screening. Small molecule fluorescent probes have gained rapid development in recent years due to their high efficiency, selectivity, and low cost. In this study, a novel phenothiazine-based fluorescent probe PHT was designed and synthesized for the quick detection of fluoride ions. PHT exhibited a response time of only 1 minute and a detection limit of 1.3 ppb. Furthermore, PHT showed a stoke shift of around 140 nm, which surpassed previous reports. Finally, the PHT probe was successfully utilized for HepG2 imaging and detection of biological samples with endemic disease.

Summary: Design and development of simple, affordable and 'turn-ON' fluorescent probes for fluoride ion sensing is an incessant research target over the decades. In this study, new benzothiophene derivatives were developed as selective fluorescent probes for trace-level fluoride ion detection. The mechanism of fluoride ion detection was elucidated using H-1 NMR and FT-IR investigations, and the experimental results were validated using an Arduino-based platform.

Summary: We synthesized a symmetrical N,N'-bis(3-(1H-imidazol-1-yl)propyl)oxalamide-based receptor OX(PID)(2) and characterized it using various physicochemical techniques. The receptor exhibited high selectivity and sensitivity towards Cu2+ and Fe3+ ions and showed cytotoxicity against MDA-MB-231 cells, suggesting its potential as an anticancer agent. The biological activities of the newly created oxalamide-based compounds were evaluated against pathogenic bacteria, showing moderate to good antibacterial activity.

Summary: This study investigates the influence of chloride and sulfate ions on the transport of cadmium (Cd) in the soil-rice system. The results show that chloride and sulfate ions increase the concentration of Cd in the soil solution, Fe plaque, and rice plants, facilitating the mobility of Cd isotopes and contributing to Cd immobilization in the Fe plaque and uptake into roots. The findings provide insights into the role of anions in Cd migration and transformation in the soil-rice system.

Summary: The main objective of the study was to synthesize 5-Ar-Rhs using Knoevenagel condensation without catalyst and investigate their sensing abilities as ion-sensing organic ligands. The 5-Ar-Rhs were obtained as the main product from the high-temperature no-catalyst reactions. The anion-sensing properties of the 5-Ar-Rhs, especially its selectivity towards F- ion, were studied using colorimetric and spectroscopic methods. The results showed that 3A and 3B are good selective candidate sensors for fluoride detection.

Summary: In this study, we designed and synthesized a colorimetric and near-infrared fluorescent probe YC-Si for F- detection. The probe selectively breaks Si-O bonds and specifically responds to F-, with a high sensitivity and a detection limit of 6.59 x 10-7 mol/L. YC-Si has a large Stokes shift at 678 nm (168 nm) and has been demonstrated to have cell permeability and low cytotoxicity for F- detection in living cells.

Summary: Bambusurils can be used for tuning and characterizing supramolecular systems by acting as anion scavengers in metal-mediated self-assemblies. They can manipulate the subtle equilibria in the system, trigger the self-assembly process, and enhance specific interactions between components. Bambusuril has the ability to selectively remove coordinating anions from mixtures, enabling regenaration of the supramolecular structure.

Summary: A new small tripodal ligand L2 has been synthesized and used for lanthanide complexation, forming stable mononuclear complexes. The crystal structure of a C-3-symmetrical mononuclear complex with Eu-III exhibits a helical wrapping of binding strands around the cation, and similar complexes are formed along the Ln(III) series. Various techniques were used to characterize the complexes, indicating their moderate stability and ability to remain unchanged in large metal excess. Luminescence lifetimes confirm the complexation of trivalent lanthanide in a single well-protected coordination environment.

Summary: This study presents a comprehensive kinetic model describing the enzymatic cleavage of hyaluronan (HA) by bovine testicular hyaluronidase (BTH), focusing on the late degradation stage. Experimental data shows that crowding conditions boost recombination events and concurrently slow down all fragmentation pathways. These findings provide valuable quantitative insights into understanding the complex reaction mechanism underlying enzymatic HA degradation.

Summary: Microscale thermophoresis (MST) and Temperature Related Intensity Change (TRIC) are newly developed measurement techniques used to quantify biomolecular interactions, but have not been as widely accepted as other biophysical techniques. A benchmark study was conducted to assess the reliability of MST/TRIC in characterizing biomolecular interactions, involving multiple scientific groups across Europe and the US, utilizing standardized procedures and centrally prepared samples.
