Evaluation of Poly(Glycidyl Methacrylate) Nanocoating for Chiral Separation with Glu-β-CD as Chiral Selector in Capillary Electrophoresis

In this paper, a capillary coated with poly(glycidyl methacrylate) nanoparticles (PGMA NPs) was prepared and applied to construct a capillary electrophoresis (CE) enantioseparation system with glucosyl- β -cyclodextrin (Glu- β -CD) as a chiral selector. The PGMA NP coating can be easily introduced through a simple ring-opening reaction. Two basic drugs were used as models to evaluate the separation performance of the PGMA coating. Under the optimal conditions selected, the separation of the two enantiomers was obtained.
