Summary: ZnSe/ZnO heterostructures were synthesized using the microwave-assisted hydrothermal method with zinc acetate and zinc nitrate as the source of Zn2+ ions. The incorporation of ZnSe into the ZnO matrix resulted in changes in the size of ZnO crystallites and lattice parameters. Optical and texture analyses showed that ZnSe particles caused a decrease in gap energy and a significant increase in the specific surface area of ZnSe/ZnO heterostructures. ZnSe/ZnO heterostructures synthesized with zinc acetate exhibited better photocatalytic performance in visible light compared to pure ZnO.

Summary: Modified Am-241-Be neutron beams can change the optical properties of zinc oxide (ZnO) photoluminescence (PL) spectra by transmuting zinc (Zn) into gallium (Ga) after irradiation. This study investigates the time required by slow neutron irradiation to register the transmutation of Zn into Ga. Two series of samples from different suppliers (TEW Tokyo Denpa Co. Ltd., Tokyo, Japan and MTI corporation, China) are irradiated for 6, 12, 18, and 24 days on the Zn-polar face of each sample to determine the relationship between irradiation intensity and transmutation.

Summary: ZnO microflowers consisting of porous nanosheets were synthesized by hydrothermal reaction and subsequent annealing at 300 degrees C. Characterization through XRD, SEM, TEM, and N-2 adsorption-desorption test revealed that the ZnO microflowers had a size of about 6 mu m, a surface area of 58.6 m(2)/g, an average pore size of 14.1 nm, and a size distribution centered at 15.1 nm. The hydrothermal temperature played a crucial role in determining the shape and size of the ZnO products. These ZnO microflowers with porous structure and large surface area show potential applications in gas sensors, photo-catalysis, electrochemical energy storage, and more. The synthetic method presented here is simple, cost-effective, and can be extended to the preparation of other metal oxides with controlled structures.

Summary: Due to its thermal stability, conductivity, high exciton binding energy and high electron mobility, zinc oxide is one of the most studied semiconductors in the field of photocatalysis. Doping the lattice with foreign atoms can introduce defects within the bandgap, making zinc oxide optically active in the visible range and reducing the energy required for photo-driven charge separation. This study demonstrates a green synthetic procedure for achieving high-level doping and highlights the importance of thermal treatment in selecting the nature of the defect and the material's capability for specific chemistry. The low-temperature treatments were found to produce material with higher efficiency in the water photosplitting reaction.

Summary: A method for fabricating ZnO/h-BN composites with tunable photoluminescence characteristics is reported. The h-BN support enhances the UV emission of ZnO nanoparticles and changes the electronic structure of the ZnO surface. Replacing h-BN nanoparticles with h-BN microparticles increases the UV photoluminescence and decreases the visible light emission. The dependence of the photoluminescence properties on the thickness of h-BN carriers is explained by the change in the dielectric constant. Density functional theory calculations show hybridization at the h-BN/wZnO interface and an increase in absorption peak intensity with an increase in the number of h-BN layers. These results open new possibilities for controlling the properties of ZnO/h-BN heterostructures for optical applications.

Summary: Based on dendrimers, a series of polyphenol compounds (P1, P2, and P3) were coordinated with iron (III) (Fe3+) to investigate the effect of polyphenol structures on their T1 contrast performance. These new Fe3+-based complexes, featuring regular amplification of their phenolic hydroxyl groups, exhibit enhanced longitudinal relaxivity (r1) due to proton exchange facilitated by a hydrogen-bonding network. Furthermore, these designed Fe3+-based complexes demonstrate good T1 contrast effect in vitro and in vivo. Modifying the coordination structure of Fe3+-based contrast agents can potentially improve their relaxivity properties and facilitate the development of excellent magnetic resonance imaging agents for disease diagnosis.

Summary: Magnetothermal therapy (MHT) is a promising non-/minimal invasive and efficient approach for tumor treatment. However, the development of small MHT agents (< 50 nm) with excellent magnetothermal conversion performance and high tumor enrichment remains challenging. In this study, a macrophage-mediated delivery system was designed for enhanced magnetic resonance imaging (MRI) and MHT of solid tumors using small Fe@Fe3O4-DHCA nanoparticles. The aggregation of Fe@Fe3O4-DHCA nanoparticles in macrophages resulted in enhanced MRI and magnetothermal performance in vitro. Moreover, the in vivo MHT effect of macrophages loaded with Fe@Fe3O4-DHCA was superior to that of Fe@Fe3O4-DHCA alone, attributed to the tumor-targeting capability of macrophages. This macrophage-mediated delivery system presents a new strategy for enhanced MHT based on Fe@Fe3O4-DHCA nanoparticles, with great potential for clinical tumor therapy.

The nanoplatform exhibited tumor microenvironment-responsive properties and could deplete glutathione to disrupt the antioxidant defense system and deliver drugs on demand. Furthermore, it could generate highly toxic hydroxyl radicals through the catalysis of released Mn2+ and produce controlled nitric oxide delivery and significant photothermal effect under 808 nm light irradiation, resulting in high mortality of cancer cells.

Summary: We developed a nanoplatform for combined chemotherapy and enhanced chemodynamic therapy by self-assembling a water-soluble and amphipathic ferrous metallacage (FM), hydrophilic copolymer (PEG2000-COOH), and oxaliplatin (OXA). The FM acted as a catalyst for the Fenton reaction and potential agent for chemodynamic therapy. OXA not only served as an anti-tumor drug but also activated intracellular enzymes to enhance the chemodynamic therapy effect. In vitro and in vivo experiments demonstrated that FM@OXA-PEG showed minimal toxicity to normal cells, while effectively killing tumor cells and inhibiting tumor growth.

Summary: This article introduces a clever combination of nano-enzymes and therapeutic drugs that can promote the production of reactive oxygen species (ROS) in cancer cells, enhancing the therapeutic efficacy of nanomedicines on malignant tumors. By loading the specific drug onto PEGylated Ce-doped hollow mesoporous silica nanoparticles, a smart nanoplatform is constructed to improve tumor therapy efficiency. The carrier showed multi-enzyme activities, with Ce3+ ions converting endogenous H2O2 into highly toxic OH for chemodynamic therapy and Ce4+ ions exhibiting catalase-like activity to reduce tumor hypoxia and glutathione (GSH) peroxidase-mimicking properties to effectively deplete GSH in tumor cells. Moreover, the loaded drug disrupts mitochondrial functions, causing the accumulation of superoxide anions (O-2(-)) and H2O2 within tumor cells. By combining the advantages of the carrier and the drug, the prepared nanoplatform can efficiently induce cancer cell death and inhibit tumor growth through significantly enhanced ROS production. Therefore, this positive combination therapy strategy has a promising application prospect for enhancing antitumor efficacy.

Summary: In this study, a pH- and glutathione (GSH)-responsive T-1-T-2 dual-mode contrast agent, Fe3O4@ZIF-8-Zn-Mn nanoparticles (NPs), was constructed to improve the sensitivity and accuracy of magnetic resonance imaging (MRI). The NPs showed good stability and weak T-1-T-2 dual-mode MRI contrast effect under neutral conditions, but could be disassembled and release Fe3O4 NPs and paramagnetic Mn2+ ions under acidic environment (pH = 6.5-5.5) and in the presence of GSH (0-4 mM), resulting in enhanced T-1 and T-2 imaging performances. In vivo MRI experiments demonstrated the potential of Fe3O4@ZIF-8-Zn-Mn NPs as a tumor microenvironment-responsive T-1-T-2 dual-mode contrast agent for sensitive tumor imaging.
