Silver (Ag) ions are successfully reduced to stable silver nanoparticles (AgNPs) using banana leaves. Conversion of Ag ions to AgNPs has been confirmed by UV-VIS analysis. The result of change on independent variables, i.e. temperature and strength of reducing agent on absorbance of solution and optimization of parameters has been done using response surface methodology (RSM) as per central composite design (CCD). The type of chemical group present on the nanoparticles is studied using fourier-transform infrared spectroscopy (FT-IR). Estimation of the size of particles has been done using transmission electron microscopy (TEM) and nanoparticle size analyzer. The crystallinity of the nanoparticles formed has been confirmed using XRD. Energy dispersive X-ray analysis (EDX) data is used to confirm the nanometal present.

香蕉叶介导的银纳米颗粒的生物合成

使用香蕉叶将银（Ag）离子成功还原为稳定的银纳米颗粒（AgNPs）。通过UV-VIS分析已经证实了Ag离子向AgNPs的转化。自变量的变化结果，即还原剂的温度和强度对溶液吸收率的影响以及参数的优化，已根据中央复合设计（CCD）使用响应表面方法（RSM）完成。使用傅立叶变换红外光谱（FT-IR）研究了纳米颗粒上存在的化学基团的类型。使用透射电子显微镜（TEM）和纳米粒度分析仪已经完成了颗粒尺寸的估算。已经使用XRD确认了形成的纳米颗粒的结晶度。能量色散X射线分析（EDX）数据用于确认存在的纳米金属。
