Nanoparticles, which have unique properties, have attracted growing attention in enantiomeric separation nowadays. In this paper, an L-cysteine functionalized gold nanoparticle (L-Cys-GNP) based capillary column was prepared and applied in separating drug enantiomers in capillary electrochromatography (CEC) with lactobionic acid (LA) as a chiral selector. Compared with bare fused-silica capillary columns, the capillary columns modified with L-Cys-GNPs showed excellent chiral separation performance. A series of parameters affecting the enantiomeric separation were systematically investigated.
具有独特性质的纳米颗粒如今在对映体分离中受到越来越多的关注。本文制备了一种基于L-半胱氨酸功能化金纳米颗粒(L-Cys-GNP)的毛细管柱,并将其应用于毛细管电色谱(CEC)中以乳糖酸(LA)作为手性选择剂分离药物对映体。与裸熔融石英毛细管柱相比,用L-Cys-GNPs修饰的毛细管柱表现出优异的手性分离性能。系统研究了一系列影响对映体分离的参数。
