“…Effect of GMA percentage in the monomer on the stability of HIPE was investigated. As reported elsewhere, the addition of GMA did compromise emulsion stability . Polar GMA interferes with the aggregation of surfactant molecules at the W/O interface, and therefore affects both coalescence and Ostwald ripening .…”

In this study, glycidyl methacrylate‐based polymerized high internal phase emulsion monolithic column (polyHIPE) with submicron skeletons and well‐defined macropores is prepared and functionalized by immobilizing heparin to obtain a novel affinity chromatographic separation medium for effective purification of Enterovirus 71 (EV71). The pore structure of the obtained monoliths differs significantly from conventional polyHIPE monoliths. The prepared polyHIPE presents well‐defined 3D network skeletons of 0.2–0.5 µm, interconnected macropores of 0.5–2 µm, large specific surface area (47–61 m2 g−1), and excellent permeability (k = 1.0 × 10−13 m2). Further, successful immobilization of heparin is proved by FTIR and XPS and the monoliths display superiority in the purification of EV71 from culture supernatant. The final recovery and binding capacity of EV71 are calculated to be 60% and 152.8 ng per column, respectively. SDS‐PAGE gel electrophoresis and TEM analysis indicate a high efficiency in the removal of impurities from culture supernatant of EV71. This, together with easy fabrication, makes polyHIPE monolith a promising alternative to commercially available monolithic supports for virus purification.

Owing to the remarkable physicochemical properties such as hydrophobicity, conductivity, elasticity, and light weight, graphene-based materials have emerged as one of the most appealing carbon allotropes in materials science and chemical engineering. Unfortunately, pristine graphene materials lack functional groups for further modification, severely hindering their practical applications. To render graphene materials with special characters for different applications, graphene oxide or reduced graphene oxide has been functionalized with different organic agents and assembled together, via covalent binding and various noncovalent forces such as π-π interaction, electrostatic interaction, and hydrogen bonding. In this review, we briefly discuss the state-ofthe-art synthetic strategies and properties of organic-functionalized graphene-based materials, and then, present the prospective applications of organic-functionalized graphene-based materials in sample preparation.

“…Although monolithic polyHIPE columns have proven advantageous as stationary phases, providing lower backpressures and decreased wall effects, they have been limited by their low surface areas (5–20 m 2 /g), which causes poor chromatographic performance . Because of their poor performance and limitations in reproducibility, the application of these macroporous columns for small‐molecule analysis has focused on their application for the preconcentration of analytes before analysis with a traditional packed column; for example, for the preconcentration of polyaromatic hydrocarbons, repeatability with the same column was measured at under 10%, and column‐to‐column reproducibility was determined to be under 13% . Additionally, knowledge of the roles of porogenic solvent in determining the final polyHIPE morphology have enhanced their repeatability .…”

The application of polymeric high-internal-phase emulsion (polyHIPE) capillary coatings for open-tubular analytical separation columns was demonstrated in this study for the first time. Multiple polystyrene-co-divinylbenzene polyHIPE layers with an average total depth of 1.73 mm were coated onto internal capillary surfaces to create open-tubular columns (20 cm coating and 32.5 cm effective length). With these columns for open-tubular capillary electrochromatography, ethylbenzene and pentylbenzene were separated. Although the overall separation capacity of the produced columns was low, the polyHIPE coatings improved the analyte peak shape, decreased the total run time, and improved the peak symmetries relative to comparable unmodified open-tubular columns. In addition, the use of these novel polyHIPE columns led to the use of 30% less organic modifier. These columns have the potential to improve the shelf life of open-tubular columns typically used in capillary electrochromatography. V C 2016 Wiley Periodicals, Inc. J. Appl. Polym.
