title: Analysis and applications of nanoparticles in the separation sciences: A case of gold nanoparticles.
abstract: Nanometer-sized gold particles-gold nanoparticles (Au NPs)-are attracting a great deal of attention for their use in various technologies, including catalysis, optical and electronic devices, and separation science. In the emerging field of nanomaterials, the design, synthesis, and characterization of nanostructures are critical features because the manipulation of these structures has a direct effect on their resulting macroscopic properties. Nanostructures fabricated in layers on surfaces-for example, through self-assembly processes-have several potential applications in separation science. This review provides an introduction to the characterizations of Au NPs using size exclusion chromatography, high performance liquid chromatography (HPLC), and electrophoresis, and their self-assembly onto solid supports for analyses based on HPLC, gas chromatography, and capillary electrophoresis. In addition, sample concentration strategies involving the use of self-assembly approaches for surface modification of Au NPs are also discussed.
