Abstract
A multilayer quasi-continuous density gradient centrifugation method for separating 20-250 nm metal colloids with high size resolution while maintaining particle stability is presented. Colloidal mixtures containing monodisperse gold nanospheres and clusters thereof, in particular, gold dimers, are purified with yields up to 94%. The rapid method uses standard laboratory equipment.
摘要
本文提出了一种多层准连续密度梯度离心方法，可在保持颗粒稳定性的同时，以高分辨力分离 20-250nm 的金属胶体。该方法可用于纯化含有单分散金纳米球和金纳米球团聚体（特别是金二聚体）的胶体混合物，收率高达 94%。该快速方法使用标准实验室设备。
