Article Abstract
A new nano-scale spherical vinyl-functionalized covalent organic polymer (TAPT-DVA-COP) with uniform sizes around 300 nm was initially constructed using 2,5-divinyl-1,4-benzaldehyde (DVA) and 2,4,6-tris(4-aminophenyl)-1,3,5-triazine (TAPT) as monomers. Then, a sulfonic acid (-SOH) modified COP termed COP-SOH was developed based on post-sythesis method employing TAPT-DVA-COP as precursor. Capillary electrochromatography (CEC) monolithic columns were fabricated using the physical doping technique to exhibit the application potential of TAPT-DVA-COP and COP-SOH. Compared to the TAPT-DVA-COP monolithic column, the COP-SOH monolithic column achieved a highly selective separation between analytes with different properties, including monosubstituted benzenes, alkylbenzenes, hydroxybenzoates, nucleoside bases, and biogenic amines. Non-covalent interaction (NCI) analysis and experimental data show that the synergism of the sulfonic acid group and aromatic moieties on COP-SOH endows the new stationary phase with diverse interactions, including ion exchange, hydrophobic, π-π and hydrogen bonding. In addition, the COP-SOH monolithic column exhibited good reproducibility and excellent potential for the determination of hydroxybenzoates in compact powders and alkylbenzenes in effluent samples.

Generally, the traditional stationary phase for liquid chromatography is the key part, but with an in situ immutable property, leading to many separation limitations. Based on the former exploration of photosensitive gas chromatography, we successfully prepared a photosensitive monolithic capillary silica column with high light transmission, taking advantage of the reversible cis-trans isomerism of azobenzene. And the cis-trans isomerism has launched an effective, reversible, and precise control on the liquid chromatographic retention behavior just by photoinduction according to the theoretical basis of a good correlation between photoinduction time, -azobenzene ratio, and chromatographic retention factor () ( > 0.

In order to enrich the selection of biological ligands, realize the miniaturization analysis, and broaden the application of monolith materials for active ingredients screening and separating, we sough to construct a lipid raft @capillary monolith microcolumn affinity chromatography model. Single factor experiments and various characterization methods, including scanning electron microscopy (SEM) and thermogravimetric analysis, were employed to investigate the polymerization of the monolith column under different material ratios to determine optimal preparation conditions. Subsequently, the lipid raft from U251 cells was integrated with the monolith materials based on epoxy-based covalent crosslinking principle and characterized through SEM and immunofluorescence methods.

Silica-based monoliths offer higher separation efficiency per unit pressure drop compared to particle-packed columns. Their application is limited by the commercial availability of different column chemistries. Pentafluorophenyl ligands enable hydrogen bonding, dipole-dipole, π-π, and hydrophobic interactions, facilitating the separation of various compounds.

Adeno-associated viruses (AAV) are becoming increasingly popular as a powerful tool for gene delivery therapy applications. Although processes to produce AAV are established, future demand for this type of viral vector requires further development of manufacturing processes to make them more robust, scalable, and flexible to accommodate the rise of engineered capsids. This study focuses on designing and evaluating a two-step chromatography process for capturing and polishing AAV8 using monolith chromatography media.

Gimeracil, a component in S-1 (an oral anticancer agent comprising tegafur, a prodrug of 5-fluorouracil (5-FU), potassium oxonate, and gimeracil), inhibits metabolic enzymes, thereby impeding 5-FU degradation. Therefore, the blood level of gimeracil is closely associated with the disposition of 5-FU, and quantification of gimeracil can provide important information if a case shows an inappropriate 5-FU blood concentration. Nevertheless, methods for quantifying gimeracil in human plasma are rarely reported.
