Summary: Graphene-assembled hollow nanospheres (GAHNs) have attracted much interest due to their outstanding multi-functional properties, including excellent compressive elasticity and plastic deformation characteristics. The morphology of force measurement tip plays a critical role in the compressive failure modes of GAHNs. With the increase of ambient temperature, the internal pressure of GAHN increases until a crack appears.

Summary: Photocatalytic reduction of U(VI) in aqueous and simulated seawater conditions was efficiently achieved using TiO2@[SO4]/CdS double-shell hollow nanospheres. The addition of [SO4]/CdS facilitated the separation and transfer of photogenerated electron-hole pairs, promoting the kinetics of photocatalytic reactions. The TiO2@[SO4]/CdS-2 catalyst showed excellent performance in removing U(VI) and maintaining stability during multiple cycles, with a significantly higher apparent rate constant compared to other catalysts.

Summary: Gold nanosphere (AuS) has inert, biocompatible properties and good cell penetration ability, making it a promising treatment method for cancer therapy when used with nanosecond laser irradiation. However, the influence of parameters on AuS-induced cell death under nanosecond laser irradiation is not well-studied, which makes it challenging to optimize gold nanoparticle-mediated anti-cancer therapy. In this study, we revealed the main parameters and threshold values for AuS-mediated gastric cancer phototherapy with nanosecond pulsed laser irradiation and evaluated the roles of photothermal, photochemical, and vapor effects on inducing cell death.

Summary: Photothermal and photodynamic therapies (PTT and PDT) can activate antitumor immunity and suppress metastatic tumors by inducing immunogenic cell death (ICD). However, mono-PTT or mono-PDT are generally insufficient and tumor microenvironment can offset the antitumor effects. In this study, a hollow germanium nanosphere (HGNs) with favorable photothermal and photodynamic effects was developed, promoting ICD of tumor cells and reversing immunosuppressive tumor microenvironment. HGNs effectively eradicated both primary and distant tumors and improved animal survival, showing great potential for clinical translation.

Summary: Three-dimensional wireframe DNA origami with programmable features can be used for prophylactic and therapeutic applications. This study investigates the immunostimulatory properties of these origami on the TLR9 pathway. Results show that bare wireframe DNA origami induce minimal TLR9 activation, but when displaying multivalent CpG-containing oligos, robust TLR9 pathway activation and enhanced immune response is observed. The study also finds that CpG copy number and spatial organization contribute to the magnitude of TLR9 signaling.

Summary: The modified superparamagnetic iron oxides (SPION-4) showed enhanced delivery of doxorubicin (DOX) to tumor tissues, inhibiting tumor growth effectively. The DOX-loaded SPION-4 exhibited faster release rates and higher concentrations in tumor tissues both in vitro and in vivo, with significantly lower concentrations in heart tissues, indicating a notable anticancer effect. The in vivo results demonstrated that the DOX-loaded SPION-4 with an external magnet had the best effects on inhibiting tumor growth compared to other groups, showing improved antivascular effects and a larger necrotic area.

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.
