Abstract

A water-soluble chitosan derivative, chitosan succinamide, was used as a polymer matrix for the formation of silver nanoparticles via ion reduction under microwave irradiation in the presence of a D-glucose reducing agent. UV spectroscopy confirmed the presence of silver nanoparticles in the synthesized colloidal solution. Transmission electron microscopy showed that the synthesized silver nanoparticles had a spherical shape. The obtained diffractograms confirm the presence of reflexes characteristic of the crystal lattice of metallic silver. In vitro studies showed that the synthesized colloidal solution of silver nanoparticles exhibits pronounced antibacterial activity against strains of the gram-positive bacteria Bacillus subtilis ATCC 6633 and Bacillus coagulans 429.

壳聚糖琥珀酰胺稳定的银纳米粒子：合成和抗菌活性。

摘要

水溶性壳聚糖衍生物壳聚糖琥珀酰胺被用作聚合物基质，用于在D-葡萄糖还原剂存在下通过微波辐射下的离子还原形成银纳米颗粒。紫外光谱证实合成的胶体溶液中存在银纳米颗粒。透射电子显微镜显示合成的银纳米颗粒具有球形形状。所获得的衍射图证实了金属银的晶格的反射特性的存在。体外研究表明，合成的银纳米颗粒胶体溶液对革兰氏阳性细菌枯草芽孢杆菌ATCC 6633和凝结芽孢杆菌429的菌株具有明显的抗菌活性。
