Summary: Systematic investigation on the adsorption performance of polystyrene-based nanospheres towards persistent organic pollutants (POPs) is crucial for high-capacity adsorbent design and toxicological risk assessment. In this study, a series of polystyrene-based nanospheres with controllable microstructures were successfully constructed as model adsorbents. It was found that F-functionalized nanospheres (xFFNs) demonstrated better enrichment effects towards PCBs due to stronger sigma (σ)-hole interactions. The xFFNs-coated SPME fiber showed excellent enrichment performance for PCBs, with detection limits of 0.08-0.89 ng L-1 for trace PCB quantification in treated sewage samples.

Summary: Here, we demonstrate the ability of a dual-purpose periodic mesoporous organosilica (PMO) probe to track the complex chlorinated paraffin (CP) composition in living animals. The PMO probe serves as an adsorbent-assisted atmospheric pressure chemical ionization Fourier-transform ion cyclotron resonance mass spectrometry (APCI-FT-ICR-MS) platform and an in vivo sampling device. The PMO probe enables synchronous solvent-free ionization and in-source thermal desorption of CP homologues, resulting in improved detection limits and the identification of potential CP metabolites in living fish.

Summary: Enzymes, as exceptional natural catalysts, play vital roles in life-sustaining biotransformations due to their exquisite 3D structures. However, their flexibility makes them vulnerable in non-physiological environments, hindering their large-scale industrial applications. This study presents a new bottom-up strategy for enzyme encapsulation using a hydrogen-bonded organic framework (HOF-101), allowing for the encapsulation of various enzymes within a highly crystalline scaffold. Compared to other methods, this enzyme-triggering HOF-101 encapsulation is easy to operate and offers higher loading efficiency, with a well-arranged structure and mesochannels that enhance mass transfer and understanding of biocatalytic processes.

Summary: This contribution comprehensively investigates the biomineralization of zeolite imidazole frameworks for one-step synthesis of an enzyme-MOF biocomposite. The study reveals that the biomineralization ability depends on the ZIF organic linker, and the biocatalytic function is highly related to the ZIF mineral species and their microstructures. Additionally, the protective effect of ZIF mineral on the hosted enzyme is associated with the synergistic effect of size dimension and chemical microenvironment of the ZIF pores.
