Quaternary Ammonium Salts-Based Materials: A Review on Environmental Toxicity, Anti-Fouling Mechanisms and Applications in Marine and Water Treatment Industries

Biomolecules, Год журнала: 2024, Номер 14(8), С. 957 - 957

Опубликована: Авг. 7, 2024

The adherence of pathogenic microorganisms to surfaces and their association form antibiotic-resistant biofilms threatens public health affects several industrial sectors with significant economic losses. For this reason, the medical, pharmaceutical materials science communities are exploring more effective anti-fouling approaches. This review focuses on properties, structure-activity relationships environmental toxicity quaternary ammonium salts (QAS) and, as a subclass, ionic liquid compounds. Greener alternatives such QAS-based antimicrobial polymers biocide release, non-fouling (i.e., PEG, zwitterions), fouling release poly(dimethylsiloxanes), fluorocarbon) contact killing properties highlighted. We also report dual-functional stimuli-responsive materials. Given impacts in submerged surfaces, we emphasize importance less explored approaches marine industry developing efficient membranes for water treatment systems.

Enlarged Cleavable Linkages in Shuriken-like Quaternary Ammonium Compounds Providing Safer Bactericides

Chemistry of Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

Although they offer great convenience in preventing microbial infections, the nondegradable feature of most commercial quaternary ammonium compounds (QACs) has led to persistent environmental accumulation, raising significant concerns about their detrimental impacts on public and ecological health. In this study, we report a kind shuriken-like QACs with rapid hydrolysis properties under mild conditions, enabled by introduction enlarged cleavable linkages as backbones. Such present potent bactericidal activity owing multicationic "heads" yet can be converted entirely harmless forms choline silicone oil after degradation. Both cytotoxicity assessment biosafety evaluation confirm nontoxic nature degradation products. The performance fruit preservation infection prevention fabric surfaces further illustrates broad application prospects such degradable within realm food safety With advantages hydrolysis, friendliness, low biotoxicity, concept an "enlarged linkage" strategy will pave way for exploiting generation disinfectants that effectively combat threats while ensuring minimal footprint.

Smart Antibacterial Fabric Response to Sweat: Constructing Reversibly Switchable Surface by Zwitterionic Block Copolymers

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Апрель 18, 2025

Although various antibacterial fabrics have been extensively developed, smart that can achieve stimulus responses not developed under high humidity conditions. In this study, a sweat-responsive fabric has designed by grafting zwitterionic PTMSPMA-co-PTMAO copolymer on cotton (CF) to "active attack" and "passive defense" against bacteria. It exhibits desirable properties in both H2O dry environments with the killing rates Escherichia coli Staphylococcus aureus reaching over 99.97%. Additionally, significant antiadhesion effects sweat environments, an rate above 99.95%. Various characterizations of PTMSPMA-co-PTMAO-CF reveal its bacteria high-humidity environments. H2O, oxygen-containing anions interact via hydrogen bond, exposing more -(CH3)2-N+ kill enhance attack." sweat, ions (such as Na+ Cl-) will be electrically neutralized quaternary ammonium cations (-(CH3)2-N+) PTMSPMA-co-PTMAO-CF, thereby significantly enhancing exhibiting also reversible conversion antiadhesion, according variations external This study provides new insight fields health monitoring, sports equipment, medical protection.
