Exposing spores to germinants in a quaternary ammonium matrix was an effective method to reduce environmental contamination by sensitizing the spores, leaving them susceptible to ambient conditions and enhancing killing by acid, high-intensity visible light, and radiation.

Quaternary ammonium salts (QAs) are a class of highly active compounds widely used in medicine and agriculture. However, many QAs lack a conjugated system, making their recognition and quantitation challenging. Stachydrine is a representative unconjugated QA with a high content in Houtt.

The widespread use of disinfectants, particularly during the coronavirus disease (COVID-19) pandemic, has significantly increased human exposure to biocides, raising concerns about their potential health risks, especially when inhaled. Benzalkonium chloride (BKC), a quaternary ammonium compound commonly used as a disinfectant and preservative, is a notable example because it is frequently used in household products and medical settings. Despite its broad usage, limited research has been conducted on the respiratory and systemic toxicities of BKC.

Fruit preservation materials play an instrumental role in preventing fruit deterioration and extending shelf life. However, existing fresh-keeping materials often prove inadequate in simultaneously achieving antibacterial properties, maintaining freshness, antioxidant effects, good biocompatibility, and prolonged fruit shelf life. Therefore, we present the first preparation of a natural polysaccharide spray hydrogel (Q/O/Zn hydrogel), loaded with chlorogenic acid‑zinc nanoparticles (CA@ZnNPs), utilizing quaternary ammonium insect chitosan (QECS) and oxidized pullulan (OPUL) for the preservation of perishable fruits.

The adsorption and aggregation of amphiphiles at different solvent interfaces are of great scientific and technological importance. In this study, interfacial tension measurements of surface-active compounds-ionic liquid 2-dodecyl-2,2dimethylethanolammonium bromide (12Cho.Br) and cationic surfactant cetyltrimethylammonium bromide (CTAB)-were conducted both in the absence and presence of ciprofloxacin (CIP).
