“… reported a CEC enantioseparation method modified with a small amount of transfersomes, which consist of phospholipids and single chain surfactant acts as an “edge activator.” A significant improvement on enantioseparation of three drugs, including propranolol, metoprolol, and esmolol, was achieved. Fu and co‐workers , inspired by strong surface adhesion and stereoselective properties of bacteria, develop a nonpathogenic E. coli strain DH5a‐modified OT column by the electrostatic interaction between bacteria and polyethyleneimine pretreated capillary column. The fabricated bacteria coated columns possess good repeatability and stability for the separation of fluoroquinolone antibiotics under optimum conditions.…”

Capillary electrochromatography, which combined the high selectivity of highperformance liquid chromatography and the high separation efficiency of capillary electrophoresis, is an attractive separation tool. In this review, the developments on monolithic and open tubular capillary electrochromatography during 2017 to August 2019 are summarized. Considering the development of novel stationary phases is the most active research field in capillary electrochromatography, monolithic capillary electrochromatography is classified according to the polymer-based and hybrid monolithic columns, while open-tubular capillary electrochromatography is categorized by cyclodextrin, silica, polymer, nanomaterials, microporous materials, and biomaterials-based open tubular columns.

“…Certain living organisms like bacteria have been well observed to possess instrinsic chirality in the microscopic and macroscopic scale and therefore being chiral systems themselves, they can exhibit properties as chiral selectors for enantioselective separations. Xia's group employed a non‐pathogenic E. coli strain DH5a adhered to a positively charged polyethyleneimine (PEI)‐coated capillary for the enantioseparation of fluoroquinolone enantiomers and simultaneous separation of six fluoroquinolone antibiotics . A bacterial concentration of 2 × 10 9 cells/mL in 12 h of coating was adopted.…”

Recent developments in open tubular capillary electrochromatography from 2016 to 2017Interest in open-tubular capillary electrochromatography (OT-CEC) continues to thrive because of the inherent advantage of OT-CEC combining the high efficiency of capillary electrophoresis and the high selectivity of high performance liquid chromatography. For the period 2016 to 2017, novel materials have been developed as first-time stationary phases for OT-CEC and are grouped in this review as polymer-based materials, frameworks, nanoparticles, graphene-based materials, and biomaterials. Coating and fabrication methods mostly rely on covalent coating strategies while non-covalent immobilisation strategies like electrostatic assembly are notably still being employed. The concern of overcoming phase ratio challenges in OT-CEC coatings have also generated adoption of combined coating strategies including multi-layering, layer-by-layer self-assembly and methods adapted from nanofilm fabrications like epitaxial growth, liquid phase deposition, or nucleation of crystal growth. The emergence of non-conventional coating characterisation methods such as transmission electron microscopy, X-ray diffraction or X-ray photoelectron spectroscopy is also discussed.

“…Chromatographic analysis using a stationary phase is the most commonly used method to improve separation. Various materials have been utilized as stationary phases, such as graphene oxide , bacteria , and porous materials . With the development of porous organic frameworks, metal‐organic frameworks (MOFs) have been broadly developed as chromatographic stationary phases.…”

In this study, a metal-organic framework (MOF), [Mn(cam)(bpy)], was synthesized and characterized by thermogravimetric analysis, scanning electron microscopy, and Fourier transform infrared spectrometry. An open-tubular capillary column was fabricated from [Mn(cam)(bpy)] via the amide coupling method. Ten types of sulfonamides were separated through the fabricated capillary column, which showed a good limits of detection (<0.07 μg/mL) and linear ranges (1-100 or 5-100 μg/mL) with a high correlation coefficients (R > 0.9987). The intra-day, inter-day and column-to-column relative standard deviations (RSDs) in the migration times ranged from 0.44 to 4.87%, and the peak area RSDs ranged from 0.80 to 7.28%. The developed capillary electrochromatography method can be successfully utilized for the determination of sulfonamides in tap water and milk samples.
