ABSTRACT

Capillary electrophoresis (CE) is a rapidly growing technique in separation sciences due to its high-resolution power, short analysis times, and low consumption of reagents and samples. CE is considered a special case of electrokinetic separation technique using an electrical field through submillimeter diameter capillaries and in micro- and nanofluidic channels to separate the components of a mixture. Nanomaterial (NM)-enhanced CE is considered an effective technique for the liquid-phase separation of various species ranging from metal ions to organic molecules to biomolecules. The applications of nano-stationary phases are rapidly rising and are changing the science of separation techniques. The large surface- area-to-volume ratio enhances the ability of the NPs to selectively interact with the capillary surface and/or the analyte yielding high mass transfer and radically changes the separation performances. This chapter highlights the recent advancements in nano- stationary phases for CE techniques and further applications.
