“…This in situ process of incorporating silica into polymeric monolith opened an avenue for the easy preparation of the organic-silica hybrid monolithic column by using organic monomers containing silanes via free radical polymerization. Due to the large surface area, nanoparticles have been exploited to modify the monolithic media to enhance the interactions between the analytes and the stationary phases, which were successfully applied for GC, CEC or CLC separation, SPE, and other fields [81]. Polyhedral oligomeric silsesquixanes (POSS) with sizes of from 1 to 3 nm in diameter can be thought of as the smallest possible organic-silica hybrid particles, as building blocks of interest in many applications of POSS-containing materials such as medical polymers, high-temperature composites, dendrimers, and liquid crystals [82].…”

Hybrid organic-silica monolithic columns, regarded as a second generation of silica-based monoliths, have received much interest due to their unique properties over the pure silicabased monoliths. This review mainly focuses on development in the fields of preparation of hybrid monolithic columns in a capillary and their application for CEC and capillary liquid chromatography separation, as well as for sample pretreatment of solid-phase microextraction and immobilized enzyme reactor since July 2010. The preparation approaches are comprehensively summarized with three routes: (i) general sol-gel process using trialkoxysilanes and tetraalkoxysilanes as coprecursors; (ii) "one-pot" process of alkoxysilanes and organic monomers concomitantly proceeding sol-gel chemistry and free radical polymerization; and (iii) other polymerization approaches of organic monomers containing silanes. The modification of hybrid monoliths containing reactive groups to acquire the desired surface functionality is also described.

“…Taken advantage of their property of large surface area, to date, the nanostructured materials, such as carbon nanotubes, silica, magnetic and non-magnetic metal oxides, silver and gold nanoparticles, have been adopted in chromatographic and electrophoretic techniques, in which nanoparticles serve as additives, or permanent/dynamic capillary inner surface coatings in capillary electrophoresis (CE) [2][3][4][5], as stationary phases in capillary electrochromatography (CEC) [6][7][8][9][10][11][12] and gas chromatography (GC) [13,14], as well as liquid chromatography (LC) [15].…”

“…micelles, nanoparticles, nanostructures, etc. ), which significantly eliminate the adsorption of highly abundant proteins on the capillary wall [50][51][52][53]. Nanomaterials have been proven to be effective (pseudo)stationary phase due to their beneficial properties, such as large surfaceto-volume ratio and easy modification.…”

Nanomaterials are attracting an interest of many researches. All this attention is due the unique physical and chemical properties of nanomaterials differing significantly from the bulk materials mainly due to their size in range of nanometers. Capillary electrophoresis (CE) is a powerful, well-established analytical technique that provides numerous valuable benefits over other separation methods including high-performance liquid chromatography. The connection between CE and nanotechnology can be approached by two strategies: (i) CE analysis of nanomaterials and (ii) nanomaterials for CE improvement. The first perspective focuses on uses of CE as a method for characterization employed during nanomaterial production and modification as well as for monitoring their properties and interactions with other molecules. The second viewpoint deals with applications of nanomaterials for improving CE performance, mainly by enhancing efficiency of separation using nanomaterials as a stationary or pseudo-stationary phase and by enhancing detection sensitivity and/or selectivity in both optical and electrochemical detection. Moreover, applications of nanomaterials for sample preparation before CE analysis will be mentioned. This chapter aims at highlighting the symbiosis of CE and nanotechnology as a combination of modern, progressive field with well-known and reliable analytical method.
