Antibacterial and anticancer activities of green-synthesized silver nanoparticles using Photinia glabra fruit extract

Aims: We prepared Photinia glabra (PG) aqueous fruit extract, utilized it to synthesize silver nanoparticles (PG-Ag NPs) and evaluated the antibacterial and anticancer activities of the nanoparticles (NPs). Materials & methods: Silver nitrate aqueous solution was reduced to PG-Ag NPs using aqueous PG fruit extract. NP shape, size, composition and functionalization were determined using transmission electron microscopy, x-ray photoelectron spectroscopy, Fourier transform infrared and x-ray diffraction. Results & conclusions: PG-Ag NPs were spherical, approximately 39–77 nm-sized, furctionalized surfaces with notable antibacterial activity against both Escherichia coli and Staphylococcus aureus, with an MIC

目的：本研究制备了 Photinia glabra (PG) 水果提取物，并以此合成银纳米颗粒（PG-Ag NPs），对纳米颗粒（NPs）的抗菌和抗癌活性进行了评估。材料与方法：通过将硝酸银水溶液还原，利用水溶性 PG 水果提取物合成 PG-Ag NPs。利用透射电子显微镜、X射线光电子能谱、傅里叶变换红外光谱和X射线衍射技术对 NPs 的形状、尺寸、组成及功能化进行了测定。结果与结论：PG-Ag NPs 呈球形，尺寸约为 39-77 nm，表面功能化，对大肠杆菌和金黄色葡萄球菌均表现出显著的抗菌活性，最小抑菌浓度（MIC）为 ...
