Chronic diabetic wounds remain a worldwide challenge for both the clinic and research. Given the vicious circle of oxidative stress and inflammatory response as well as the impaired angiogenesis of the diabetic wound tissues, the wound healing process is disturbed and poorly responds to the current treatments. In this work, a nickel‐based metal‐organic framework (MOF, Ni‐HHTP) with excellent antioxidant...
Direct electrocatalytic reduction of N2 to NH3 under mild conditions is attracting considerable interests but still remains enormous challenges in terms of respect of intrinsic catalytic activity and limited electrocatalytic efficiency. Herein, a photo‐enhanced strategy is developed to improve the NRR activity on Cu single atoms catalysts. The atomically dispersed Cu single atoms supported TiO2 nanosheets...
In thrombotic diseases, the effects of reactive oxygen species (ROS)‐mediated oxidative stress as a “perpetrator” in thrombosis must be resolved. Accordingly, an insufficient understanding of thrombus therapy prompted the authors to pursue a more comprehensive and efficient antithrombotic treatment strategy. A Prussian blue (PB)‐based nanodroplet system (PB‐PFP@PC) is designed using PB and perfluorinated...
The multirelaxation behavior is promising for high‐performance dielectric materials based on polarization‐controllable high‐efficiency electromagnetic attenuation. However, a single polar unit is the main problem that restricts the development of dielectric materials in the field. Herein, by constructing multiple polar units based on nanodomain engineering, enhanced electromagnetic attenuation properties...
Next‐generation desalination technologies are needed to meet the increasing demand for clean water. Capacitive deionization (CDI) is a thermodynamically efficient technique to treat non‐potable water with relatively low salinity. The salt removal capacity and rate of CDI are highly dependent on the electrode materials, which are preferentially porous to store ions through electrosorption and/or redox...
The encapsulation of specific nanoentities into hollow nanomaterials derived from metal organic frameworks has attracted continuous and growing research attentions owing to their unique structural properties and unusual synergistic functions. Herein, using the phase transformation of uniform rhombi dodecahedron ZIF‐67, hollow nano‐shell with a well‐defined morphology is successfully prepared. Particularly,...
Highly efficient charge separation has been demonstrated as one of the most significant steps playing decisive roles in enhancing the overall efficiency of photoelectrochemical (PEC) processes. In this study, by employing 5,10,15,20‐tetrakis (4‐carboxyphenyl) porphyrin‐Ni (NiTCPP) as a prototype, an oxygen vacancy (Vo)‐mediated reverse regulation strategy is proposed for tuning hole transfer, which...
Here, the photocatalytic CO2 reduction reaction (CO2RR) with the selectivity of carbon products up to 100% is realized by completely suppressing the H2 evolution reaction under visible light (λ > 420 nm) irradiation. To target this, plasmonic Au/CdSe dumbbell nanorods enhance light harvesting and produce a plasmon‐enhanced charge‐rich environment; peripheral Cu2O provides rich active sites for...
Quasi‐two‐dimensional (QTD) structural heterogeneous catalysts have attracted a broad interest in multidisciplinary research due to their unique structure, preeminent surface properties and outstanding catalytic performance. Herein, a HZIF@TCPP‐Fe/Fe heterogeneous catalyst based on cross‐linked surface engineering is constructed by supporting QTD TCPP‐Fe/Fe ultra‐thin metallized film (≈2 nm) on hollow...
Metal halide perovskite has attracted enhanced interest for its diverse electronic and optoelectronic applications. However, the fabrication of micro‐ or nanoscale crystalline perovskite functional devices remains a great challenge due to the fragility, solvent, and heat sensitivity of perovskite crystals. Here, a strategy is proposed to fabricate electronic and optoelectronic devices by directly...
Efficient charge separation and sufficiently exposed active sites are important for light‐driving Fenton catalysts. 0D/2D hybrids, especially quantum dots (QDs)/nanosheets (NSs), offer a better opportunity for improving photo‐Fenton activity due to their high charge mobility and more catalytic sites, which is highly desirable but remains a great challenge. Herein, a 0D hematite quantum dots/2D ultrathin...
Autophagy is a biological process that has attracted considerable attention as a target for novel therapeutics. Recently, nanomaterials (NMs) have been reported to modulate autophagy, which makes them potential agents for the treatment of autophagy‐related diseases. In this study, zinc oxide nanoparticles (ZNPs) are utilized to evaluate NM‐induced autophagy and debate the mechanisms involved. It is...
In article number 1803788, Manli Wang, Yiwu Zhou, and co‐workers systematically dissect the dynamic entry process of an emerging tick‐borne bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV), by using multicolor tracking of quantum dot‐labeled single‐particles. SFTSV is internalized into clathrin‐coated pits, further delivered to endosomes and finally fused at an approximate pH...
The Bunyavirales is one of the largest groups of RNA viruses, which encompasses many strains that are highly pathogenic to animals and humans. Severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging tick‐borne bunyavirus that causes severe disease in humans, with a high fatality rate of up to 30%. To date, the entry process of bunyavirus infection remains obscure. Here, using quantum...
In article number 1800785, Guobin Wang, Shuai Wang, Zheng Wang, Lin Wang, and co‐workers fabricate a versatile nanoplatform composed of gold‐nanodot‐decorated hollow carbon nanospheres with hyaluronic acid coating (AuHCNs‐HA). Such a nanoplatform serves as a trimodal drug delivery and therapeutic system. Using this system, their work reveals that weak photothermal effects and weak photodynamic effects...
Despite the therapeutic usefulness of near‐infrared irradiation (NIR)‐induced potent photothermal effects (PTE) and photodynamic effects (PDE), they inevitably damage normal tissues, often posing threat to life when treating tumors adjacent to key organs or major blood vessels. In this study, the frequently overlooked, “weak” PTE and PDE (no killing capability) are employed to synergize chemotherapy...
High‐efficient charge and energy transfer between nanocrystals (NCs) in a bottom‐up assembly are hard to achieve, resulting in an obstacle in application. Instead of the ligands exchange strategies, the advantage of a continuous laser is taken with optimal wavelength and power to irradiate the film‐scale NCs superlattices at solid–liquid interfaces. Owing to the Au‐based NCs' surface plasmon resonance...
Sericin‐wrapped mesoporous silica nanoparticles (SMSNs) with pH and protease dual responsiveness are successfully fabricated as a lysosome‐targeting drug delivery system by Guobin Wang, Lin Wang, Zheng Wang, and co‐workers in article number 1602567. Such a dual responsive system offers a rapid doxorubicin release in lysosomes, which bypasses the membrane pump mediated drug efflux, thereby achieving...
Multidrug resistance (MDR) and adverse side effects are the major challenges facing cancer chemotherapy. Here, pH/protease dually responsive, sericin‐coated mesoporous silica nanoparticles (SMSNs) for lysosomal delivery of doxorubicin (DOX) to overcome MDR and reduce systemic toxicity are reported. Sericin, a natural protein from silkworm cocoons, is coated onto MSNs as a gatekeeper via pH sensitive...
