Graphene-coated polymeric anion exchangers for ion chromatography

"Graphene Derivates Carbon Products and Separation Properties : The m R.N.A. Purification-Affinity ,Ion Exchange and other Chromatographic Application- Sample Testing -Research and Large Scale m R.N.A. Production"

“…template that can then be removed after IVT using affinity chromatography . Despite being scalable, these methods present a limited effectiveness since they only focus on the removal of some specific impurities and hence must be coupled with other purification steps [3]" "Carbonaceous stationary phases have gained much attention for their peculiar selectivity and robustness. we report the fabrication and application of a graphene-coated polymeric stationary -phase for the anion exchange chromatography.…”

Nanomaterial-functionalized Cellulose: Design, Characterization and Analytical Applications

“…The authors tested the assay with nitrated ceruloplasmin with a detection limit of 8 ng/mL in undiluted plasma and 0.4 ng/mL for spiked plasma which demonstrates a greater sensitivity compared to gold immunoassays. 68 Technical aspects and challenges in the development of microfluidic paper-based analytical devices with colorimetric detection have recently been reviewed by Carrilho et al 69 In addition to Au and AgNPs, CeO2NPs that contain dual oxidation state at their surface (Ce 4+ /Ce 3+ ) 27 have been used as sensing particles. These NPs have rich surface hydroxyl functionalities when placed in an aqueous environment which allow for facile modification and complex formation.…”

Nanoparticles of zirconium hydrophosphate framed with a weakly-acidic cation-exchange polymer

“…At last, the subclass (iii) is formed by magnetic nanoparticles: their core is a magnetic material coated with functionalized polymer (shell) [25][26][27][28]. Particles consisting of polymer core and inorganic shell are considerably larger: with size of several microns and more [29,30]. Some sorbents of this type are applied to controlled drug-delivery systems [29].…”
