Novel sonosensitizers with intrinsic characteristics for tumor diagnosis, efficient therapy, and tumor microenvironment regulation are appealing in current sonodynamic therapy. Herein, a manganese (Mn)‐layered double hydroxide‐based defect‐rich nanoplatform is presented as a new type of sono‐chemo sensitizer, which allows ultrasound to efficiently trigger reactive oxygen species generation for enhanced...
Developing efficient and robust anodic electrocatalysts to implement the proton‐exchange membrane (PEM) electrolyzer is critical for hydrogen generation. Nevertheless, the only known applicable anode catalyst IrOx in PEM electrolyzers still requires high overpotential due to the weak binding energy between oxygen intermediates and active sites, limiting its wide applications. Herein, a ternary Ir0.7...
The slow kinetics and poor structural stability prevent transition metal selenides from being widely used in sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs). Herein, the “flower‐like” porous carbon anchored by Zn‐Mn binary selenides (ZMS@FC) composites are fabricated by selenizing the modified hierarchically metal‐organic frameworks. The 2D conductive hierarchically flakes’ abundant...
Water electrolysis affords a promising approach to large‐scale hydrogen yield, but its efficiency is restrained by the sluggish water dissociation kinetics. Here, an efficient bifunctional electrocatalyst of in situ formed crystalline nickel metaphosphate on amorphous NiMoOx nanoarrays supported on nickel foam (c‐Ni2P4O12/a‐NiMoOx/NF) for both hydrogen evolution reaction (HER) and oxygen evolution...
Co‐based bimetallic metal–organic frameworks (MOFs) have emerged as a kind of promising electrocatalyst for oxygen evolution reaction (OER). However, most of present works for Co‐based bimetallic MOFs are still in try‐and‐wrong stage, while the OER performance trend and the underlying structure‐function relationship remain unclear. To address this challenge, Co‐based MOFs on carbon cloth (CC) (CoM...
Carbon materials with multilevel structural features are showing great potentials in electromagnetic (EM) pollution precaution. With ZIF‐67 microcubes as a self‐sacrificing precursor, hierarchical carbon microcubes with micro/mesoporous shells and hollow cavities have been successfully fabricated with the assistance of rigid SiO2 coating layers. It is found that the SiO2 layer can effectively counteract...
Nanotheranostics have been actively sought in precision nanomedicine in recent years. However, insufficient tumor accumulation and limited cell uptake often impede the nanotheranostic efficacy. Herein, pH‐sensitive charge‐reversible polymer‐coated layered double hydroxide (LDH) nanohybrids are devised to possess long circulation in blood but reserve surface charges in the weakly acidic tumor tissue...
19F magnetic resonance imaging (19F MRI) agents capable of being activated upon interactions with cancer triggers are attracting increasing attention, although challenges still remain for precise and specific detection of cancer tissues. In this study, a novel hybrid 19F MRI agent for pH‐sensitive detection of breast cancer tissues is reported, a composite system designed by conjugating a perfluoropolyether...
Cancer immunotherapy is a promising cancer terminator by directing the patient's own immune system in the fight against this challenging disorder. Despite the monumental therapeutic potential of several immunotherapy strategies in clinical applications, the efficacious responses of a wide range of immunotherapeutic agents are limited in virtue of their inadequate accumulation in the tumor tissue and...
Responsive nanoprobes play an important role in bioassay and bioimaging, early diagnosis of diseases and treatment monitoring. Herein, a upconversional nanoparticle (UCNP)‐based nanoprobe, Ru@UCNPs, for specific sensing and imaging of hypochlorous acid (HOCl) is reported. This Ru@UCNP nanoprobe consists of two functional components,, i.e., NaYF4:Yb, Tm UCNPs that can convert near infrared light‐to‐visible...
Developing facile routes for fabricating highly efficient oxygen evolution reaction (OER) electrocatalysts is in great demand but remains a great challenge. Herein, a novel molten salt decomposition method to prepare 3D metal nitrate hydroxide (MNH, M = Ni, Co, and Cu) nanoarrays homogenously grown on different conductive substrates, especially on nickel foam (NF) for OER applications, is reported...
Cu nanocrystals of various shapes are synthesized via a universal, eco‐friendly, and facile colloidal method on Al substrates using hexadecylamine (HDA) as a capping agent and glucose as a reductant. By tuning the concentration of the capping agent, hierarchical 3D Cu nanocrystals show pronounced surface‐enhanced Raman scattering (SERS) through the concentrated hot spots at the sharp tips and gaps...
Nanomaterials have been widely tested as new generation vaccine adjuvants, but few evoke efficient immunoreactions. Clay nanoparticles, for example, layered double hydroxide (LDH) and hectorite (HEC) nanoparticles, have shown their potent adjuvanticity in generating effective and durable immune responses. However, the mechanism by which clay nanoadjuvants stimulate the immune system is not well understood...
2D transition metal dichalcogenides materials are explored as potential surface‐enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T′) rhenium disulfide (ReS2) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al2O3 dielectric layer unambiguously reveal that Raman enhancement on...
Self‐propelled Au‐BP7@SP Janus‐like nanohybrids with active motion under NIR laser can effectively enhance the temperature of tumors, potentially by converting the kinetic energy into thermal energy, enhancing photothermal tumor therapy.
