Abstract

Synthesis of silver nanoparticles-chitosan composite particles sphere (AgNPs-chi-spheres) has been completed and its characterization was fulfilled by UV-vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and zetasizer nano. UV-vis spectroscopy characterization showed that AgNPs-chi-spheres gave optimum absorption at a wavelength of 410 nm. The XRD spectra showed that the structure of AgNPs-chi-spheres were crystalline and spherical. Characterization by SEM showed that AgNPs-chi-spheres, with the addition of 20% of NaOH, resulted in the lowest average particle sizes of 46.91 nm. EDX analysis also showed that AgNPs-chi-spheres, with the addition of a 20% NaOH concentration, produced particles with regular spheres, a smooth and relatively nonporous structure. The analysis using zetasizer nano showed that the zeta potential value and the polydispersity index value of the AgNPs-chi-sphere tended to increase with an increased NaOH concentration. The results of the microbial activity screening showed that the AgNP-chi-Spheres with highest concentration of NaOH, produced the highest inhibition zone diameters against , , and , with inhibition zone diameters of 19.5, 18.56, and 12.25 nm, respectively.

摘要

银纳米颗粒-壳聚糖复合颗粒球（AgNPs-chi-spheres）的合成已经完成，并通过紫外可见光谱、傅里叶变换红外（FT-IR）光谱、X射线衍射（XRD）、扫描电子显微镜（SEM）和纳米粒度分析仪进行了表征。紫外可见光谱表征表明，AgNPs-chi-spheres在410nm波长处有最佳吸收。XRD光谱表明，AgNPs-chi-spheres的结构为晶体且呈球形。SEM表征表明，添加20%的NaOH时，AgNPs-chi-spheres的平均粒径最小，为46.91nm。能谱分析（EDX）还表明，添加20%NaOH浓度时，AgNPs-chi-spheres产生的颗粒呈规则球形，结构光滑且相对无孔。使用纳米粒度分析仪的分析表明，随着NaOH浓度的增加，AgNPs-chi-sphere的zeta电位值和多分散指数值趋于增加。微生物活性筛选结果表明，NaOH浓度最高的AgNP-chi-Spheres对、和产生的抑菌圈直径最大，分别为19.5、18.56和12.25nm。
