Summary: A density-adjusted liquid-phase microextraction combined with smartphone digital image colorimetry was established for rapid, convenient, and environmentally friendly determination of parathion-methyl in food samples. The environmentally friendly solvent guaiacol was used as the extractant, and salt and water were used to adjust the density to ensure full contact between the extractant and the sample solution. Parathion-methyl generated a yellow product under strong alkaline conditions, and a smartphone was used for intensity analysis. The method showed a good linear relationship in the range of 0.01-1 mg L-1, with low limits of detection and quantification. The method was successfully applied to various food samples with high recovery and low relative standard deviation.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.

Summary: Effective management of biofluids is crucial for in vivo surgical interventions. Recent advances include self-sealing needles, drug-eluting stents, and shear-thinning hydrogels. However, complications associated with intestinal mucosal injury and secondary damage still persist. In this study, researchers developed an interpenetrating Janus wettability stent coating that enables unidirectional draining of excessive biofluid. They also demonstrated directional biofluid movement using a self-pumping dressing with potential applications in biofluid collection and disease diagnosis through metal ion detection. This integrated system presents an opportunity for designing wound dressings with effective biofluid management and metal ion detection capabilities.
