扬州大学化学化工学院开发的“抗菌性高吸水性树脂研制”关键技术取得重要突破,将纳米银成功地均匀结合在高吸水性树脂表面。纳米级银系抗菌剂的抗菌机制是:银离子与细菌接触后,到达微生物细胞壁,带正电荷的银离子吸附在带负电荷的细胞壁上,依靠库仑力使两者牢固吸附。银离子穿透细胞壁进入细胞内,与—SH基反应,使蛋白质凝固,使微生物细胞发生破裂而死亡,影响微生物所需基本物质的传输,破坏细胞合成酶的活性,用中断DNA复制的形式阻止微生物繁殖。当
Yangzhou University School of Chemistry and Chemical Technology developed “antibacterial superabsorbent resin research and development,” the key breakthrough made an important breakthrough in the successful integration of silver nanoparticles in the superabsorbent surface. Antibacterial mechanism of nano-silver antibacterial agent is: silver ions and bacteria contact, reach the microbial cell wall, positively charged silver ions adsorbed on the negatively charged cell wall, rely on Coulomb force so that the two firmly adsorbed. Silver ions penetrate the cell wall into the cell, and -SH-based reaction, the protein coagulation, microbial cell rupture and death, affecting the basic material required for microbial transmission, destruction of cell-synthesizing enzyme activity, with the interruption of DNA replication in the form of blocking Microbial breeding. when
