A light-activated NO donor, [Mn(PaPy(3))(NO)]ClO(4) (1a), has been incorporated into HEMA-based polymer hydrogel and the nitrosyl-polymer conjugate materials 1a(x) · HG and 1a(x) · HG(MB) have been characterized. The NO releasing properties and antibacterial capabilities of these materials in conjunction with growth attenuators such as hydrogen peroxide and methylene blue (MB) are reported. Since the nitrosyl releases NO only upon exposure to light, materials like 1a(x) · HG(MB) could be used as wound dressings that deliver NO under controlled conditions.
一种光激活的一氧化氮供体[Mn(PaPy(3))(NO)]ClO(4)(1a)已被掺入到 HEMA 基聚合物水凝胶中,并且已经对亚硝酰聚合物缀合物材料 1a(x)·HG 和 1a(x)·HG(MB)进行了表征。报道了这些材料的一氧化氮释放特性和抗菌能力,以及与过氧化氢和亚甲基蓝(MB)等生长抑制剂的协同作用。由于只有在暴露于光下时,亚硝酰才会释放一氧化氮,因此像 1a(x)·HG(MB)这样的材料可以用作在受控条件下释放一氧化氮的伤口敷料。
