Summary: Due to the high incidence and poor prognosis of acute pancreatitis (AP) and its easy transformation into pancreatic cancer (PC), early diagnosis and prevention of AP have become important research focuses. In this study, a magnetic single-drop microextraction (SDME) system with spatial confinement was proposed to enhance the aggregation-induced emission (AIE) effect for simultaneous fluorescence detection of miRNA-155 (associated with AP) and miRNA-196a (associated with PC). The method achieved low limits of detection and wide linear ranges, and was successfully applied to detect miRNAs in human serum samples.

Summary: A high-performance liquid chromatography method combined with pulsed amperometric detection was used to separate impurities of paromomycin. However, direct coupling to mass spectrometry for identifying the chemical structures of the impurities was not feasible due to the presence of ion pairing agents and sodium hydroxide in the mobile phase. By incorporating a cation self-regenerating suppressor, most of the interfering acids in the mobile phase were removed, significantly improving the limit of detection for paromomycin.

Summary: A highly sensitive method for detecting aflatoxin B1 (AFB1) was developed using a peroxidase-like spatial network structure. The method involved coating specific antibody and antigen of AFB1 on a histidine-modified Fe3O4 nanozyme to form capture/detection probes. The probes constructed a spatial network structure through competition/affinity effect, which could be rapidly separated through a magnetic three-phase single-drop microextraction process. The method achieved a low detection limit (0.034 pg/mL) due to the strong peroxidase-like ability of the network structure and the enrichment effect of microextraction.

Summary: This study proposed a novel strategy using peroxymonosulfate (PMS) activated by Fe-loaded sodium alginate hydrogel beads (Fe-SA) to enhance anaerobic fermentation (AF) performance. The experimental results showed that Fe-SA and PMS co-pretreatment synergistically enhanced waste activated sludge (WAS) solubilization and volatile fatty acids (VFAs) production. Mechanistic studies revealed that Fe-SA greatly induced the generation of reactive radicals from PMS, which contributed to WAS disintegration and degradation of refractory compounds.
