Summary: We successfully prepared mesoporous polymer microspheres with uniform pore size using aqueous suspension polymerization. The size and pore size of the microspheres can be independently controlled, and they exhibit a nanostructured bicontinuous morphology. We also demonstrated the incorporation of functional pore walls and showed the high efficiency of the microspheres in dye removal. This method has great potential for applications in catalysis, chromatography, and water remediation.

Summary: Hierarchically porous spherical particles were successfully prepared using high internal phase water-in-oil-in-water double emulsions through visible-light photopolymerization. The thiol-to-acrylate ratio was found to affect the microsphere diameter and degradation speed, with increased acrylate content leading to slower degradation. Functionalization with allylamine and adsorption capabilities of the microspheres were also demonstrated in the study.

Summary: A new method of water-compatible noncovalent imprinted microspheres was proposed to overcome the challenges in preparing molecularly imprinted polymers (MIPs) with specific recognition in aqueous solution. The method involved screening functional monomers using molecular dynamics (MD) and preparing spherical MIPs with a modified suspension polymerization method. The synthesized SPM-MIP and CDCA-MIP showed high adsorption capacities, selectivity, and resistance to protein adsorption in an aqueous medium.

Summary: The synthesis of cassava starch magnetic porous microspheres (AAM-MSMPMs) was accomplished through graft copolymerization in inverse emulsion. The resulting AAM-MSMPM adsorbent exhibited superparamagnetic behavior and demonstrated a high capacity for the adsorption of Cd(II) ions in aqueous solution. The addition of a porogen resulted in a decrease in particle size, an increase in specific surface area, and an enhancement in adsorption capacity. The adsorption process on the AAM-MSMPM followed Langmuir isothermal and pseudo-second-order kinetic models, with chemisorption as the rate-controlling step. The AAM-MSMPM also displayed excellent stability after multiple reuses.

Summary: The suspension polymerization process was used to create acrylate resin microspheres for mesh coating technology. The synthesized microspheres had mesh numbers of 140-200 µm and particle sizes of 100 µm. The optimal reaction conditions for synthesis were determined to be a dispersant dosage of 30 g of calcium carbonate, a monomer ratio of 4:1, a reaction time of 1 h, an initiator dosage of 1.2 g of BPO, and a reaction temperature of approximately 75-80 °C, resulting in microspheres with a regular spherical shape and smooth surface.

Summary: Highly porous lignin-based microspheres modified with magnetite nanoparticles were used for the first time to remove Se(VI) selenate anions from water samples. The research investigated the influence of experimental conditions on the adsorption capacity and analyzed the structural and morphological properties of the adsorbent. The adsorbent showed high affinity for Se(VI) oxyanion but limited potential for multi-cycle material application, making it suitable as a Se fertilizer.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
