It is believed of great interest to incorporate silver nanoparticles (Ag-NPs) into stable supported materials using biological methods to control the adverse properties of nanoscale particles. In this study, in-situ biofabrication of Ag-NPs using aqueous extract in () fiber as supporting material was used in which, the extract acted as both reducing and stabilizing agents to incorporate Ag-NPs in the fiber. The properties of Ag-NPs incorporated in the fiber (/Ag-NPs) were characterized using UV-visible spectroscopy (UV-vis), X-ray Diffraction (XRD), Field Emission Transmission Electron Microscope (FETEM), Scanning Electron Microscope (Scanning Electron Microscope (SEM), Energy Dispersive X-ray (EDX), Brunauer-Emmett-Teller (BET), Thermogravimetric (TGA) and Fourier Transform Infrared (FTIR) analyses. The average size of Ag-NPs measured using FETEM image was 4.74 nm spherical in shape. The /Ag-NPs was easily separated after application, and could control the release of Ag-NPs to the environment due to its strong attachment in fiber. The /Ag-NPs exposed good qualitative and quantitative antibacterial activities against (ATCC 25923), (ATCC 29212), (ATCC 25922) and (ATCC 33420). The dye catalytic properties of /Ag-NPs revealed the dye reduction time in which it was completed within 4 min for 20 mg/L rhodamine B and 20 min for 20 mg/L methylene blue dye, respectively. Based on the results, it is evident that /Ag-NPs are potentially promising to be applied in wound healing, textile, wastewater treatment, food packaging, labeling and biomedical fields.
人们认为，利用生物方法将银纳米颗粒（Ag-NPs）掺入稳定的载体材料中以控制纳米级颗粒的不良特性具有极大的意义。在本研究中，使用（）纤维中的水提取物作为载体材料原位生物制备Ag-NPs，其中该提取物既作为还原剂又作为稳定剂，将Ag-NPs掺入纤维中。使用紫外可见光谱（UV-vis）、X射线衍射（XRD）、场发射透射电子显微镜（FETEM）、扫描电子显微镜（扫描电子显微镜（SEM））、能量色散X射线（EDX）、布鲁诺尔-埃米特-泰勒（BET）、热重分析（TGA）和傅里叶变换红外（FTIR）分析对掺入纤维中的Ag-NPs（/Ag-NPs）的特性进行了表征。使用FETEM图像测量的Ag-NPs的平均尺寸为4.74 nm，呈球形。/Ag-NPs在应用后易于分离，并且由于其在纤维中的强附着性，可以控制Ag-NPs向环境中的释放。/Ag-NPs对金黄色葡萄球菌（ATCC 25923）、大肠杆菌（ATCC 29212）、铜绿假单胞菌（ATCC 25922）和白色念珠菌（ATCC 33420）表现出良好的定性和定量抗菌活性。/Ag-NPs的染料催化特性显示了染料还原时间，其中对于20 mg/L罗丹明B在4分钟内完成，对于20 mg/L亚甲基蓝染料在20分钟内完成。基于这些结果，很明显/Ag-NPs在伤口愈合、纺织、废水处理、食品包装、标记和生物医学领域具有潜在的应用前景。
