Abstract The radical proliferation of pathogenic bacteria and their infections causes significant issues for human health and the environment. Today, biopolymers are used to produce different nanoparticles. In the present investigation, the fabricated chitosan/agar-silver nanoparticles (Cht/Ar-AgNPs)-coated papers were tested for antibacterial applications. Agar was used as a reducing agent for the synthesis of AgNPs. Synthesized Ar-AgNPs were examined through optical, phase crystallinity and topological analysis. Cht and Ar-AgNPs solution was mixed with various ratios of 9:1, 8:2, 7:3, 6:4, and 5:5 by weight. In addition to that, the conformity of Cht/Ar-AgNPs-coated papers was characterized by structural, spectral, and morphological analysis. However, Cht/Ar-AgNPs-coated papers were subjected to antibacterial properties. The ratio of (6:4) Cht/Ar-AgNPs-coated paper showed excellent antibacterial agent, and it can be used as extending the food product shelf life.

用于抗菌应用的壳聚糖/琼脂-银纳米粒子涂层纸的开发

摘要 病原菌的大量繁殖及其感染给人类健康和环境带来了重大问题。今天，生物聚合物被用来生产不同的纳米颗粒。在本研究中，对制备的壳聚糖/琼脂银纳米粒子 (Cht/Ar-AgNPs) 涂层纸进行了抗菌应用测试。琼脂被用作合成 AgNPs 的还原剂。通过光学、相结晶度和拓扑分析来检查合成的 Ar-AgNPs。Cht 和 Ar-AgNPs 溶液以 9:1、8:2、7:3、6:4 和 5:5 的各种重量比混合。除此之外，Cht/Ar-AgNPs 涂层纸的一致性通过结构、光谱和形态分析进行表征。然而，Cht/Ar-AgNPs 涂层纸具有抗菌性能。(6:
