Preparation and characterization of lysine-immobilized poly(glycidyl methacrylate) nanoparticle-coated capillary for the separation of amino acids by open tubular capillary electrochromatography

Preparation and characterization of tentacle-type polymer stationary phase modified with graphene oxide for open-tubular capillary electrochromatography

“…Furthermore, the analytical time of the whole running process was much shorter than that on monolithic columns. In addition, it is worth mentioning that the results obtained on the separation of amino acids and E-PE isomers by capillary electrochromatography were better than other related researches [26,31,32] considering of the resolution, separation efficiency and peak shape. In a word, the polymer coated open tubular capillary column with GO immobilization displayed some relevant advantages such as simple and timesaving preparation procedure, high analytical efficiency and satisfactory repeatability.…”

Fabrication and BSA Adsorption/Desorption Properties of Titania/Silica Composite Films Modified with Silane Coupling Agents

“…The abovementioned results indicated that the present composite films can change the BSA adsorption/desorption behavior under light irradiation. Furthermore, surface modification with silane coupling agents having various terminal functional groups has been used for the separation of amino acids 5,6 . The present methodology is expected to lead to novel separation materials with the promise to enable the separation of amino acids through photoinduced superhydrophilicity and through interactions between the amino acids and terminal functional groups.…”

Carboxyl modified magnetic nanoparticles coated open tubular column for capillary electrochromatographic separation of biomolecules

“…For the past two decades, NPs with unique physical and chemical properties have made a significant contribution to the development of stationary phases in CEC, such as carbon NPs [9][10][11][12], silica NPs [13,14], metallic and metal-oxide NPs [15][16][17][18], and polymer NPs [1]. As one kind of extensively studied NPs, magnetic nanoparticles (MNPs) have received great attention for their superior characteristics such as good dispersion, excellent biocompatibility [20], high field irreversibility, ease of preparation, high ratio of surfaceto-volume [19] and remarkable physicochemical stability.…”

“…Capillary electrochromatography (CEC) combining high selectivity of high-performance liquid chromatography and high efficiency of capillary electrophoresis has been widely applied in the analysis of biomolecules including amino acids [1], peptides [2] and proteins [3]. As the core of CEC, various forms of columns including packed, monolithic, and open tubular (OT) columns are commonly used.…”
