Severe burn wounds usually destroy key cells’ functions of the skin resulting in delayed re‐epithelization and wound regeneration. Promoting key cells’ activities is crucial for burn wound repair. It is well known that keratinocyte growth factor‐2 (KGF‐2) participates in the proliferation and morphogenesis of epithelial cells while acidic fibroblast growth factor (aFGF) is a key mediator for fibroblast...
Traditional surface‐enhanced Raman scattering (SERS) sensors rely heavily on the use of plasmonic noble metals, which have limitations due to their high cost and lack of physical and chemical stability. Hence, it is imperative to explore new materials as SERS platforms that can withstand high temperatures and harsh conditions. In this study, the SERS effect of molybdenum boride ceramic powders is...
In nature, many organisms respond chemotactically to external chemical stimuli in order to extract nutrients or avoid danger. Inspired by this natural chemotaxis, micro/nanomotors with chemotactic properties have been developed and applied to study a variety of disease models. This chemotactic strategy has shown promising results and has attracted the attention of an increasing number of researchers...
Planar gliding along with anisotropic lattice strain of single‐crystalline nickel‐rich cathodes (SCNRC) at highly delithiated states will induce severe delamination cracking that seriously deteriorates LIBs’ cyclability. To address these issues, a novel lattice‐matched MgTiO3 (MTO) layer, which exhibits same lattice structure as Ni‐rich cathodes, is rationally constructed on single‐crystalline LiNi...
Supramolecular hydrogels involved macrocycles have been explored widely in recent years, but it remains challenging to develop hydrogel based on solitary macrocycle with super gelation capability. Here, the construction of lantern[33]arene‐based hydrogel with low critical gelation concentration (0.05 wt%), which can be used for efficient oil–water separation, is reported. The lantern[33]arenes self‐assemble...
Nanochannel‐based confinement effect is a fascinating signal transduction strategy for high‐performance sensing, but only size confinement is focused on while other confinement effects are unexplored. Here, a highly integrated nanochannel‐electrodes chip (INEC) is created and a size/volume‐dual‐confinement enzyme catalysis model for rapid and sensitive bacteria detection is developed. The INEC, by...
Tendon stem/progenitor cells (TSPCs) therapy is a promising strategy for enhancing cell matrix and collagen synthesis, and regulating the metabolism of the tendon microenvironment during tendon injury repair. Nevertheless, the barren microenvironment and gliding shear of tendon cause insufficient nutrition supply, damage, and aggregation of injected TSPCs around tendon tissues, which severely hinders...
To achieve a high separation efficiency of photogenerated carriers in semiconductors, constructing high‐quality heterogeneous interfaces as charge flow highways is critical and challenging. This study successfully demonstrates an interfacial chemical bond and internal electric field (IEF) simultaneously modulated 0D/0D/1D‐Co3O4/TiO2/sepiolite composite catalyst by exploiting sepiolite surface‐interfacial...
Graphite phased carbon nitride (g‐C3N4) has attracted extensive attention attributed to its non‐toxic nature, remarkable physical–chemical stability, and visible light response properties. Nevertheless, the pristine g‐C3N4 suffers from the rapid photogenerated carrier recombination and unfavorable specific surface area, which greatly limit its catalytic performance. Herein, 0D/3D Cu‐FeOOH/TCN composites...
Diabetic Wound Healing
In article number 2205489, Jinshan Guo, Keke Wu, and co‐workers develop an on‐demand removable, pH‐responsive europium‐releasable and photothermal antimicribal adhesive dressing for diabetic wound healing. The adhesive provides convenient non‐invasive wound closure, enables in‐time painless dressing change upon mixing with borax solution, and smoothly connects inflammatory microenvironment...
Current diabetic wound treatments remain unsatisfactory due to the lack of a comprehensive strategy that can integrate strong applicability (tissue adhesiveness, shape adaptability, fast self‐healability, and facile dressing change) with the initiation and smooth connection of the cascade wound healing processes. Herein, benefiting from the multifaceted bonding ability of tannic acid to metal ions...
Asymmetric plasmonic hierarchical nanostructures (HNs) are of great significance in optics, catalysis, and sensors, but the complex growth kinetics and lack of fine structure design limit their practical applications. Herein, a new atom absorption energy strategy is developed to achieve a series of Au–Ag HNs with the continuously tuned contact area in Janus and Ag island number/size on Au seeds. Different...
A route is developed for directly growing 2D Au polyhedron arrays with controllable exposed facets of polyhedron by utilizing the substrate‐supported 2D Au quasi‐spherical nanoparticle arrays as the Au seed arrays, which cannot be realized by traditional lithography. In the reaction system, polyvinyl pyrrolidone (PVP) plays a vital role in guiding the reduced Au atoms and stabilizing the substrate‐supported...
This work reports the design of a wavelength sensor composed of two identical perovskite (FA0.85Cs0.15PbI3) photodetectors (PDs) that are capable of discriminating incident wavelength in a quantitative way. Due to strong wavelength‐dependent absorption coefficient, the penetration depth of the photons in the FA0.85Cs0.15PbI3 nanofilms increases with the increasing wavelength, leading to a gradual...
A simple cryo‐transfer method to fabricate ultrathin, stretchable, and conformal epidermal electrodes based on a combination of silver nanowires (AgNWs) network and elastomeric polymers is developed. This method can temporarily enable the soft elastomers with much higher elastic modulus and dimensional contraction through exploiting their glass‐transition behaviors. During this process, a much higher...
Monodentate adsorption of oxygen intermediates results in a theoretical overpotential limit of ≈0.35 V for oxygen evolution reaction (OER), which causes the sluggish kinetics of the OER process. In this work, nonprecious chromium dopant is introduced into the self‐supported CoFe layered double hydroxides (LDHs) on nickel foam (Cr‐CoFe LDHs/NF) via a facile one‐step hydrothermal method, which exhibits...
Surface modifications of plasmonic nanoparticles with metal adsorbates are essential in applications such as plasmonic sensing, plasmon‐enhanced photocatalysis, etc., where spectral broadening is usually observed. A single particle study is presented on plasmon damping by adsorption of platinum (Pt) clusters. Single particle dark‐field spectroscopy is employed to measure exactly the same gold nanorod...
