ABSTRACT

Current research focuses on a simple and effective green approach using Tamarix aphylla leaves as capping and reducing agent for the synthesis of silver nanoparticles. The synthesised Ag-NPs were characterised by UV–vis spectroscopy, FTIR, EDX, XRD and SEM analysis. The synthesis of Ag-NP was optimised by examining pH and temperature at different proportions of the reactant mixture. The UV–vis spectra displayed the optimised peak at 440 nm. The SEM image demonstrated the size of Ag-NP to be 20–60 nm and a shape close to spherical and poly dispersity. The XRD analysis manifested face-centred cubic symmetry with a size of 20–25 nm. FTIR analysis was performed to indicate the potential functionalities that may effectively stabilise Ag-NP. The synthesised Ag-NPs were screened for various biological assays.

摘要

目前的研究重点是一种简单有效的绿色方法，使用柽柳叶作为合成银纳米粒子的封盖剂和还原剂。通过紫外-可见光谱、FTIR、EDX、XRD 和 SEM 分析对合成的 Ag-NPs 进行了表征。通过检查不同比例的反应物混合物的 pH 值和温度，优化了 Ag-NP 的合成。紫外-可见光谱在 440 nm 处显示出优化的峰值。SEM 图像显示 Ag-NP 的尺寸为 20-60 nm，形状接近球形和多分散性。XRD分析显示面心立方对称，尺寸为20-25 nm。进行 FTIR 分析以表明可能有效稳定 Ag-NP 的潜在功能。筛选合成的 Ag-NPs 用于各种生物测定。
