Gold and silver nanoparticles were synthesized via mild alkoxide reduction of Ag⁺ and AuCl₄^- in water, under alkaline conditions. Three non-toxic polyols (glycerin, β-cyclodextrin (βCD), and a polymer (of β-cyclodextrin)) were employed in each case as reducing and capping agent. TEM analysis revealed larger nanoparticles when glycerin was used, followed by β-cyclodextrin, and finally by the polymer. Different numbers of population maxima in nanoparticles size distribution from one alkoxide to another were observed and such variation was dependent on alkoxide’s structure complexity. In UV–Vis spectra the typical bands for gold and silver nanoparticles were detected. ζ-potential measurements showed more electrostatically stable capping layer for glycerin and βCD. For the polymer, the stability of the layer should be a result of bulk effects.

On the other hand, Ag-Au bi-metallic nanoparticles with core–shell structure were obtained using glycerin and β-cyclodextrin, whereas a mixture of gold and silver nanoparticles was the result with the polymer. The latter was corroborated via TEM images, EDX, UV–Vis, ζ-potential, and DLS measurements. A systematic study was carried out to elucidate the influence of the different alkoxide molecules on the properties of the resulting nanoparticles.

金和银纳米颗粒通过轻度还原醇盐的Ag合成⁺和AUCL ₄ ^-在碱性条件下的水中。在每种情况下，使用三种无毒的多元醇（甘油，β-环糊精（βCD）和聚合物（β-环糊精））作为还原剂和封端剂。TEM分析显示，当使用甘油，其次是β-环糊精，最后是聚合物时，纳米颗粒更大。观察到从一种醇盐到另一种醇盐的纳米颗粒尺寸分布中不同数量的种群最大值，并且这种变化取决于醇盐的结构复杂性。在紫外-可见光谱中，可以检测到金和银纳米颗粒的典型谱带。ζ电位测量显示，甘油和βCD的静电覆盖层更牢固。对于聚合物，该层的稳定性应该是整体效应的结果。

另一方面，使用甘油和β-环糊精获得了具有核-壳结构的Ag-Au双金属纳米颗粒，而聚合物则得到了金和银纳米颗粒的混合物。后者通过TEM图像，EDX，UV-Vis，ζ电位和DLS测量得到了证实。进行了系统的研究，以阐明不同醇盐分子对所得纳米粒子性能的影响。
