Single-pot biosynthesis of silver and gold quasi-spherical nanoparticles (SNPs and GNPs) in the size range of 10-30 nm was attempted using Chenopodium album (an obnoxious weed). This method is rapid, facile, convenient and environmentally safe. Average crystal size was approximately 12 nm and 10 nm for silver and gold nanocrystals respectively. Synthesized NPs were stable in a wide range of pH as there was less variation in zeta potential values. In synthesis of SNPs and GNPs, naturally occurring oxalic acid played significant role in bio-reduction of silver nitrate and auric acid solution into their corresponding silver and gold nano-colloids in single step rapid process.
使用藜（一种讨厌的杂草）尝试了在 10-30nm 范围内的单一锅法合成银和金准球形纳米粒子（SNP 和 GNP）。该方法快速、简便、方便且环境安全。银和金纳米晶体的平均晶体尺寸分别约为 12nm 和 10nm。由于 ζ 电位值的变化较小，因此合成的 NPs 在很宽的 pH 范围内稳定。在 SNP 和 GNP 的合成中，天然存在的草酸在将硝酸银和金酸溶液一步快速还原成相应的银和金纳米胶体中起重要作用。
