Abstract

Metal-containing materials promising for wound dressings were obtained using a collagen-chitosan matrix (ColChit), quercetin (Q), and silver nanoparticles (AgNPs) synthesized using an environmentally friendly metal-vapor synthesis (MVS). Hybrid systems were prepared from collagen and chitosan modified with a silver nanoparticle-quercetin conjugate (AgNPs@Q) dissolved in glutamic acid solution, followed by gelation and lyophilization. The composition and electronic state of the metal in the resulting porous ColChitAgNPs@Q sponges were studied using XPS, TEM, and SEM/EDS. It was established that AgNPs are distributed uniformly throughout the bulk of the material and the metal is in the Ag⁰ and Ag⁺ states.

纳米银与槲皮素偶联修饰的胶原-壳聚糖复合材料

利用胶原-壳聚糖基质（ColChit）、槲皮素(Q)和银纳米粒子（AgNPs），采用环境友好型金属蒸汽合成（MVS）方法合成了具有良好应用前景的金属材料。将纳米银-槲皮素偶联物（AgNPs@Q）修饰的胶原蛋白和壳聚糖溶解在谷氨酸溶液中，凝胶化和冻干，制备杂交体系。利用XPS、TEM和SEM/EDS对制备的ColChitAgNPs@Q多孔海绵中金属的组成和电子态进行了研究。结果表明，AgNPs均匀分布在整个材料中，金属处于Ag0和Ag+态。
