Synthesis and antimicrobial applications of 5,5′-ethylenebis[5-methyl-3-(3-triethoxysilylpropyl)hydantoin]

Effect of DksA Protein on the Susceptibility of Escherichia coli Towards Novel Amine N-Halamine Polymeric Nanoparticles as Powerful Antibiotics

“…Thereby, nano-sized N-halamines could appear more overwhelming bactericidal activity over their bulk powder counterparts which has been proven repeatedly in our previous reports (Dong et al, , 2011a(Dong et al, -c, 2013(Dong et al, , 2014a. Stability is another decisive factor determining the antibacterial activity and even the subsequent applications of N-halamines (Barnes et al, 2006). N-halamines can be composed of one or more imide/amide/amine N-halamine bond and their stability is in an order of amine>amide>imide N-halamine (Gutman et al, 2014).…”

Antibacterial Modification of Textiles Using Nanotechnology

“…This hinders enzymatic and metabolic processes, leading to the destruction of the microorganisms. As an N-H bond, which does not have antimicrobial properties, is formed in the substitution reaction, further exposure of the agent to dilute sodium hypochlorite is needed for regeneration of its antimicrobial activity [23,24] . N-halamines can be applied to various textile surfaces including cellulose [25][26][27], polyamide [28] and polyester [29] fibers.…”

“…N-halamines can be applied to various textile surfaces including cellulose [25][26][27], polyamide [28] and polyester [29] fibers. To increase their effectiveness and the durability of the antimicrobial finish [25], research has been oriented toward synthesis of N-halamide monomers with an incorporated vinyl reactive group ( Figure 3) [30,31] that can polymerize on cellulose fibers under appropriate conditions to form a coating with excellent durability after washing [30]. …”

“…The ISO (International Organization for Standardization) has developed a test method (ISO 20743) in which bacteria are "printed" onto the surface of textiles without them being in an aqueous suspension [25,26]. The printed samples are then incubated under humid conditions at 20°C for a specified time (18-24 h) following which the surviving cells are counted.…”

Antimicrobial Agents and Applications on Polymeric Materials

“…Other N-halamine siloxane monomer precursors, which are 5,5'-ethylenebis[5-methyl-3-(3-triethoxysilylpropyl)hydantoin] and 3-[3-triethoxysilylpropyl-7,7,9,9-tetramethyl-1,3,8-triazaspiro [4.5]decane-2,4-dione (TS), and a polymer precursor, poly [3-(7,7,9,9-tetramethyl-1,3,8-triazaspiro[4.5]decane-2,4-dion-3-yl )propylhydroxy siloxane] (PTS) were applied onto cotton fabrics 82,83) . Grafting is another method to incorporate N-halamine precursors on textiles.…”
