Molybdenum disulfide (MoS2) has been proved as an excellent potential hydrogen evolution reaction (HER) catalyst. Compared with thermodynamically stable 2H‐MoS2, 1T‐MoS2 exhibits higher conductivity and catalytic activity, whereas it is usually difficult to prepare since of thermodynamically metastable. Herein, a feasible method is reported to fabricate ambient‐stable MoS2 with high concentration...
Pulmonary fibrosis, a sequela of lung injury resulting from severe infection such as severe acute respiratory syndrome‐like coronavirus (SARS‐CoV‐2) infection, is a kind of life‐threatening lung disease with limited therapeutic options. Herein, inhalable liposomes encapsulating metformin, a first‐line antidiabetic drug that has been reported to effectively reverse pulmonary fibrosis by modulating...
The precise regulation of interactions of specific immunological components is crucial for controllable immunomodulation, yet it remains a great challenge. With the assistance of advanced computer design, programmable nucleic acid nanotechnology enables the customization of synthetic nucleic acid nanodevices with unprecedented geometrical and functional precision, which have shown promising potential...
Combining two kinds of electron transport layer (ETL) which have complementary advantages into a bilayer structure to form a bilayer ETL is an effective way to transcend inherent limitations of single‐layer ETL, which is very helpful in the development of perovskite solar cells (PSCs). In this work, a strategy is proposed to break constraints on the application of the staggered bilayer ETL in high‐efficiency...
Islet transplantation is a promising strategy for type 1 diabetes mellitus (T1DM) treatment, whereas implanted‐associated foreign body reaction (FBR) usually induces the necrosis of transplanted islets and leads to the failure of glycemic control. Benefiting from the excellent anti‐biofouling property of zwitterionic materials and their successful application in macroscopic implanted devices, microcapsules...
Tumor radiofrequency ablation (RFA) is a local and minimally invasive application using high temperature to induce coagulative necrosis of tumor, which has been commonly used in clinic. Although the tumor fragments generated by RFA can activate the host's immune system, it may be insufficient to inhibit cancer recurrence due to many factors such as the inefficient antigen presentation by dendritic...
Ultrathin nickel (Ni)‐based sulfide nanosheets have been reported as excellent electrocatalysts for overall water splitting; however, the uncontrollability over thickness due to the nonlayered structure still hampers its practical application. Herein, a simple topochemical conversion strategy is employed to synthesize cobalt‐doped Ni3S2 (Co‐Ni3S2) ultrathin nanosheets on Ni foam. The Co‐Ni3S2 nanosheets...
The production of oxygen by photosynthetic microorganisms (PSMs) has recently attracted interest concerning the in vivo treatment of multiple diseases for their photosynthetic oxygen production in vivo, since PSMs have good biological safety. Here, the first evidence that PSMs can be used as a photothermal source to perform biophotothermal therapy (bio‐PTT) is provided. In vitro and in vivo experiments...
Semiconducting molecules have been employed to passivate traps extant in the perovskite film for enhancement of perovskite solar cells (PSCs) efficiency and stability. A molecular design strategy to passivate the defects both on the surface and interior of the CH3NH3PbI3 perovskite layer, using two phthalocyanine (Pc) molecules (NP‐SC6‐ZnPc and NP‐SC6‐TiOPc) is demonstrated. The presence of lone electron...
Nanozymes with high catalytic activity and great stability have attracted increasing interests as the promising alternative to natural enzymes for applications in various fields. In this study, a new type of highly efficient peroxidase‐like nanozymes based on FeWOX nanosheets (NSs) synthesized by a thermal‐decomposition method is reported. Owing to the sheet‐structure with maximized utilization of...
Despite the promises of applying nano‐photosensitizers (nano‐PSs) for photodynamic therapy (PDT) against cancer, severe tumor hypoxia and limited tumor penetration of nano‐PSs would lead to nonoptimized therapeutic outcomes of PDT. Therefore, herein a biocompatible nano‐PS is prepared by using tamoxifen (TAM), an anti‐estrogen compound, to induce self‐assembly of chlorin e6 (Ce6) modified human serum...
In this research, bulk graphitic carbon nitride (g‐C3N4) is exfoliated and transferred to the carbon nitride nanosheets (CNNSs), which are then coupled with MIL‐88B(Fe) to form the hybrid. From the results of the powder X‐ray diffraction, scanning electronic microscopy and thermogravimetric analysis, it is found that the doping of CNNSs on the surface of MIL‐88(Fe) could maintain the basic structure...
Although nanoparticle‐based drug delivery systems have been widely explored for tumor‐targeted delivery of radioisotope therapy (RIT), the hypoxia zones of tumors on one hand can hardly be reached by nanoparticles with relatively large sizes due to their limited intratumoral diffusion ability, on the other hand often exhibit hypoxia‐associated resistance to radiation‐induced cell damage. To improve...
