Hollow mesoporous manganese (HMM)-based nanocarriers, incorporating nanoparticle cavities and mesoporous channels, enhance the photostability and photobleaching resistance of indocyanine green (ICG). The addition of H2N-c(RGDfK)-OH (RGD) ensures precise targeting, making the cRGD&PEG2000-HMM@ICG (R&P-M@ICG) nanoprobe ideal for NIR-II fluorescence image-guided surgery and photothermal therapy (PTT). This approach offers accurate targeting, high therapeutic efficacy, and reduced side effects. The inclusion of manganese (Mn) in the nanocarriers further boosts the therapeutic effects by enabling chemodynamic therapy (CDT). Mn ions catalyze the conversion of hydrogen peroxide (HO) into highly reactive hydroxyl radicals (•OH) within the tumor microenvironment. The synergy between Mn-driven CDT and PTT enhances tumor ablation, as the heat from PTT accelerates ROS production from CDT, leading to more effective tumor cell damage and apoptosis. The dual action of PTT and CDT overcomes the limitations of single-modal therapies. While PTT induces hyperthermia to kill tumor cells, Mn-assisted CDT amplifies the ROS generation, further enhancing treatment efficacy. This combined effect makes the R&P-M@ICG nanoprobe a powerful tool for cancer treatment, demonstrating superior anti-tumor efficacy compared to conventional therapies. In this study, we synthesized the R&P-M@ICG nanoprobe, highlighting its potential for precise surgical navigation, and for synergistic photothermal and chemodynamic therapy in cancer treatment.

Controlling the growth of nanocrystals is one of the most challenged issues in current catalytic field, which helps to further understand the size and morphology related behaviors for catalytic applications. In this work, we investigated the plane growth kinetics of Mg（OH）2 for catalytic application in preferential CO oxidation. Nanoflakes were synthesized through hydrothermal method. The morphology and structure of nanoflakes were characterized by TEM, SEM, and XRD. By varying the reaction temperature and time, Mg（OH）2 nanoflakes un- derwent an anisotropic growth. Benefited from the Ostwald ripening process, the thickness of nanoflake corre- sponding to the （110） plane of Mg（OH）2 was tuned from 7.6 nm to 24.0 nm, while the diameter of （001） plane in- creased from 18.2 nm to 30.2 nm. The grain growth kinetics for the thickness was well described in terms of an equation, D5= 7.65＋ 6.9 × 10^8exp（-28.14/RT）. After depositing Pt nanoparticles onto these Mg（OH）2 nanoflakes, an excellent catalytic performance was achieved for preferential CO oxidation in H2-rich streams with a wide temper- ature window from 140 ℃ to 240 ℃ for complete CO conversion due to the interaction between Pt and hydroxyl groups. The findings reported here would be helpful in discovering novel catalysts for application of proton ex- change membrane fuel cells.

Simultaneous removal of Cu(Ⅱ) and Cr(Ⅵ) by Mg–Al–Cl layered double hydroxide and mechanism insight

Mg-A1-C1 layered double hydroxide （C1-LDH） was prepared to simultaneously remove Cu（II） and Cr（VI） from aqueous solution. The coexisting Cu（II）（20 mg/L） and Cr（VI）（40 mg/L） were completely removed within 30 min by C1-LDH in a dosage of 2.0 g/L; the removal rate of Cu（II） was accelerated in the presence of cr（VI）. Moreover, compared with the adsorption of single Cu（II） or Cr（VI）, the adsorption capacities of C1-LDH for Cu（II） and Cr（VI） can be improved by 81.05% and 49.56%, respectively, in the case of coexisting Cu（II）（200 mg/L） and Cr（VI）（400 mg/L）. The affecting factors （such as solution initial pH, adsorbent dosage, and contact time） have been systematically investigated. Besides, the changes of pH values and the concentrations of Mg2＋ and A13＋ in relevant solutions were monitored. To get the underlying mechanism, the C1-LDH samples before and after adsorption were thoroughly characterized by X-ray powder diffraction, transmission electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. On the basis of these analyses, a possible mechanism was proposed. The coadsorption process involves anion exchange of Cr（VI） with C1- in C1-LDH interlayer, isomorphic substitution of Mg2＋ with Cu2＋, formation of Cu2CI（OH）3 precipitation, and the adsorption of Cr（VI） by Cu2CI（OH）3. This work provides a new insight into simultaneous removal of heavy metal cations and anions from wastewater by CI-LDH.

Near-infrared (NIR) II luminescence between 1000 and 1700 nm has attracted reviving interest for biosensing due to its unique advantages such as deep-tissue penetration and high spatial resolution. Traditional NIR-II probes such as organic fluorophores usually suffer from poor photostability and potential long-term toxicity. Herein, we report the controlled synthesis of monodisperse NaCeF4:Er/Yb nanocrystals (NCs) that exhibit intense NIR-II emission upon excitation at 980 nm. Ce3+ in the host lattice was found to enhance the luminescence of Er3+ at 1530 nm with a maximum NIR-II quantum yield of 32.8%, which is the highest among Er3+-activated nanoprobes. Particularly, by utilizing the intense NIR-II emission of NaCeF4:Er/Yb NCs, we demonstrated their application as sensitive homogeneous bioprobes to detect uric acid with the limit of detection down to 25.6 nM. Furthermore, the probe was detectable in tissues at depths of up to 10 mm, which enabled in vivo imaging of mouse organs and hindlimbs with high resolution, thus revealing the great potential of these NaCeF4:Er/Yb nanoprobes in deep-tissue diagnosis. © 2018 The Royal Society of Chemistry.

Angewandte Chemie 2020年第23期132卷

Porous tantalum nitride (Ta 3 N 5 ) single crystals, combining structural coherence and porous microstructure, would substantially improve the photoelectrochemical performance. The structural coherence would reduce the recombination of charge carriers and maintain excellent transport properties while the porous microstructure would not only reduce photon scattering but also facilitate surface reactions. Here, we grow bulk‐porous Ta 3 N 5 single crystals on a two‐centimeter scale with (002), (023), and (041) facets, respectively, and show significantly enhanced photoelectrochemical performance. We show the preferential facet growth of porous crystals in a lattice reconstruction strategy in relation to lattice match and lattice channel. We present the facet engineering to enhance light absorption, exciton lifetime and transport properties. The porous Ta 3 N 5 single crystal boosts photoelectrochemical oxidation of alcohols with the (002) facet showing the highest performance of >99 % alcohol conversion and >99 % aldehyde/ketone selectivity.

Recent theoretical studies revealed that two-dimensional (2D) antimonene has attractive characteristics, such as superior photothermal conductivity, absorption over a wide range, high mobility, and good spintronic properties. Herein, we report a reliable liquid phase exfoliation (LPE) route for the preparation of high-quality high-stability atomically thin (AT) antimonene via high ultrasonic power. The AT antimonene delivers a high specific capacity of up to 860 mA·h·g~(–1), with high rate capability and good cycling stability as an anode of a sodium ion battery (SIB). The good conductivity and 2D structure endow AT antimonene with more active sites for sodium storage, a facilitated pathway for electron transfer and mass transport, and the capability to reduce the volume expansion during the discharge–charge process.

Although tumor-specific neoantigen-based cancer vaccines hold tremendous potential, it still faces low cross-presentation associated with severe degradation via endocytosis pathway. Herein, a thiolated nano-vaccine allowing direct cytosolic delivery of neoantigen and Toll like receptor 9 agonist CpG-ODN is developed. This approach is capable of bypassing the endo-/lysosome degradation, increasing uptake and local concentration of neoantigen and CpG-ODN to activate antigen-presenting cells, significantly strengthening the anti-cancer T-cell immunity. In vivo immunization with thiolated nano-vaccine enhanced the lymph organ homing and promoted the antigen presentation on dendritic cells, effectively inhibited tumor growth, and significantly prolonged the survival of H22-bearing mice. Strikingly, further combination of the thiolated nano-vaccine with anti-programmed cell death protein-1 antibody (PD-1) could efficiently reverse immunosuppression and enhance response rate of tumors, which led to enhanced tumor elimination, complete prevention of tumor re-challenge, and long-term survival above 150 d. Collectively, a versatile methodology to design cancer vaccines for strengthening anti-cancer T-cell immunity in solid tumors is presented, which could be further remarkably enhanced by combining with immune checkpoint inhibitors.
