The addition of silver(i) ions to the methylene glycol-sulphite (MGS) clock reaction results in the sudden formation of metallic silver nanoparticles. Stable suspensions are obtained in the presence of poly(vinylpyrrolidone). The time delay before the appearance of the particles, as well as their size, decreases with the initial methylene glycol concentration while their monodispersity increases.
向亚硫酸甲酯二醇（MGS）时钟反应中添加银（I）离子会导致金属银纳米颗粒突然形成。在聚乙烯吡咯烷酮存在下可获得稳定的悬浮液。颗粒出现前的时间延迟及其尺寸随初始亚硫酸甲酯二醇浓度的降低而减小，而其单分散性则增加。
