The balance of normal anion concentrations in cells provides basis for maintaining cellular morphology and function. Disrupting the homeostasis of cellular anions and lysosomal pH, in particular with high selectivity for cancer cells over normal cells may serve as a promising approach for the treatment of cancers. Small-molecule organic compounds with transmembrane anion transport activity, namely synthetic anion transporters are able to destroy the homeostasis of cellular anions, in particular chloride anions to trigger cell death and thus may be developed as a new class of anti-tumor drugs. This paper reviews the latest advance in the investigation into the in vitro anion transport, promising anti-tumor activity and probable mechanism of biological action of synthetic anion transporters. The strategies for optimizing the biological activity of synthetic anion transporters and improving the selectivity for cancer cells over normal cells are also discussed.

One method of achieving spatially specific, multi-component nanoheterostructures is to combine multiple forms of post-synthetic modification. Applying cation or anion exchange to CuS nanorods creates complex nanoheterostructures. Combining such anion and cation exchanges generates a system which uncovers the interplay between these two processes and understands the cooperativity between postsynthetic modifications more broadly.

In this study, we utilized drinking water treatment sludge (WTS) to produce adsorbents through the drying and calcination process. These adsorbents were then evaluated for their ability to remove azithromycin (AZT) from aqueous solutions. The L-500 adsorbent, derived from the calcination (at 500°C) of WTS generated under conditions of low turbidity in the drinking water treatment plant, presented an increase in the specific surface area from 70.

This review highlights recent advancements and challenges in fluorescence-based chemical sensors for selective and sensitive detection of perchlorate, a persistent environmental pollutant and global concern due to its health and safety implications. Perchlorate is a highly persistent inorganic pollutant found in drinking water, soil, and air, with known endocrine-disruptive properties due to its interference with iodide uptake by the thyroid gland. Human exposure mainly occurs through contaminated water and food.

Atomically precise nanoclusters can be assembled into ordered superlattices with unique electronic, magnetic, optical and catalytic properties. The co-crystallization of nanoclusters with functional organic molecules provides opportunities to access an even wider range of structures and properties, but can be challenging to control synthetically. Here we introduce a supramolecular approach to direct the assembly of atomically precise silver nanoclusters into a series of nanocluster‒organic ionic co-crystals with tunable structures and properties.

This study reports the isolation and characterization of highly resistant bacterial and microalgal strains from an Egyptian wastewater treatment station to cyanide-containing compounds. The bacterial strain was identified as Bacillus licheniformis by 16S rRNA gene sequencing. The isolate removed up to 1 g L potassium cyanide, 3 g L benzonitrile, and 1 g L sodium salicylate when incubated as 10% v/v in MSM at 30 ℃.
