Durable Antibacterial and Antifouling Cotton Fabric Fabricated Using a Combination of Grafting Through Method and Mist Polymerization Technology

Highly active nanoparticle enhanced rapid adsorption-killing mechanism to combat multidrug-resistant bacteria

“…However, after contacting PP ANPQ-11% , all the bacteria in the suspension were adsorbed within 10 s. The bacterial killing ratio of PP ANPQ-11% reached 99.99% after 30 s and all bacteria were killed within 1 min. ANPQ-11% coating performed noticeably better than other coating materials, such as small molecular organics, 27,37 linear quaternary ammonium salts, [11][12][13][14] inorganic nanoparticles, 38,39 metals, and metal oxide nanoparticles. 8,[40][41][42][43] To investigate the adsorption-killing mechanism of ANPQ-11% coating, the bacteria were stained with crystal violet dye under Live/Dead staining.…”

“…Among the most prevalent selections for developing such surfaces are antimicrobial peptides, quaternary ammonium compounds, and polycations. [11][12][13][14] Benefitting from the advantages of cost-effectiveness, ease of scaleup, and less susceptibility to antibiotic resistance, cationic polymer nanoparticles have recently gained widespread attention. [15][16][17][18][19][20] In contrast to monovalent systems, these nanoparticles have multiple ligands that can bind to several receptors on microbial membranes, leading to stronger interactions.…”

Nonleaching Antimicrobial Cotton Fabrics Finished with Hyperbranched Polylysine

“…Nonleaching antimicrobial fabrics are constructed by chemically bonding antimicrobial agents on the fabric surfaces and kill the microbes by destroying the integrity of the cell membrane through electrostatic interaction. , Chemical bonding inhibits the dissolution of the antimicrobial agent, greatly improving the safety and washing durability of nonleaching antimicrobial fabrics. − There is only one kind of commercial silicone quaternary ammonium salt antimicrobial agents that can be obtained in the market . Various new finishing strategies and antimicrobial agents have been designed and developed to overcome this limitation. − Chen et al synthesized a series of reactive antimicrobial finishing agent, siloxane sulfopropylbetaine (SSPB), zwitterionic sulfopropylbetaine (NCO-sulfopropylbetaine), and isocyanate group (NCO)-containing quaternary ammonium salt (IQAS), to prepare various durable antimicrobial CF surfaces.…”
