Summary: In this study, a thermoelectric induced surface-enhanced Raman scattering (SERS) substrate consisting of ZnO nanorod arrays and metal nanoparticles is proposed. It is demonstrated that the thermoelectric-induced enhancement of the SERS signals should be classified as a chemical contribution, and the electric regulation mechanism is proven to be universally applicable. Moreover, the fabricated substrate exhibits significant enhancement for various types of molecules and can be used to monitor and manipulate plasmon-activated redox reactions.

Summary: In this paper, the local electric field (LEF) characteristics of a multilayer silver nanoparticle were studied through simulations. It was found that increasing the layers improved the LEF intensity on the glass support, while only two layers were required on the gold film support to achieve the maximum LEF intensity. Experimental results confirmed the simulation findings. The optimized 2-layer silver nanoparticle@gold film exhibited high SERS sensitivity and signal uniformity, with a detection limit of 1 x 10(-15) M for Rhodamine 6G and a relative standard deviation of 11% for the signal intensity.

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.
