The reduction of carbon dioxide to valuable chemicals through enzymatic processes is regarded as a promising approach for the reduction of carbon dioxide emissions. In this study, an in vitro multi‐enzyme cascade pathway is constructed for the conversion of CO2 into dihydroxyacetone (DHA). This pathway, known as FFFP, comprises formate dehydrogenase (FDH), formaldehyde dehydrogenase (FaldDH), formolase...
Biofilm is a spatially organized community formed by the accumulation of both microorganisms and their secretions, leading to persistent and chronic infections because of high resistance toward conventional antibiotics. In view of the tunable physicochemical properties and the related unique biological behavior (e.g., size‐, shape‐, and surface charge‐dependent penetration, protein corona endowed...
The exponential interest in covalent organic frameworks (COFs) arises from the direct correlation between their diverse and intriguing properties and the modular design principle. However, the insufficient interlamellar interaction among COF nanosheets greatly hinders the formation of defect‐free membranes. Therefore, developing a methodology for the facile fabrication of these materials remains an...
Nanozyme activity relies on surface electron transfer processes. Notably, the piezoelectric effect plays a vital role in influencing nanozyme activity by generating positive and negative charges on piezoelectric materials' surfaces. This article comprehensively reviews the potential mechanisms and practical applications of regulating nanozyme activity through the piezoelectric effect. The article...
Homochiral supramolecular assembly (HSA) based on achiral molecules has provided important clues to understand the origin of biological homochirality from the aspect of symmetry breaking. However, planar achiral molecules still face the challenge of forming HSA due to the lack of driving force for twisted stacking, which is a prerequisite for homochirality. Here, with the benefit of the formation...
The utilization of dendritic cell (DC) vaccines is a promising approach in cancer immunotherapy, and the modification of DCs for the expression of tumor‐associated antigens is critical for successful cancer immunotherapy. A safe and efficient method for delivering DNA/RNA into DCs without inducing maturation is beneficial to achieve successful DC transformation for cell vaccine applications, yet remains...
2D metal halides have attracted increasing research attention in recent years; however, it is still challenging to synthesize them via liquid‐phase methods. Here it is demonstrated that a droplet method is simple and efficient for the synthesis of multiclass 2D metal halides, including trivalent (BiI3, SbI3), divalent (SnI2, GeI2), and monovalent (CuI) ones. In particular, 2D SbI3 is first experimentally...
Spin Droplets
In article number 2300158, Jing Liu and co‐workers report the phenomenon of liquid metal droplet spin on ice induced by a spontaneous dual solid‐liquid phase transition, just like dancing on ice. The droplet motion is lubricated by a thin water film and driven by the escaping bubbles as the ice melts. Such spin effect is disclosed to be universal for different objects including liquid...
The non‐contact and non‐wetting droplet motion isolated from the solid surface has a high degree of freedom and thus can exhibit many peculiar interfacial phenomena. Here, an experimental phenomenon of spinning liquid metal droplets on an ice block is discovered, which adopts the dual solid‐liquid phase transition of the liquid metal and the ice. The whole system is somewhat a variant of the classic...
Constructing wrinkled structures on the surface of materials to obtain new functions has broad application prospects. Here a generalized method is reported to fabricate multi‐scale and diverse‐dimensional oxide wrinkles on liquid metal surfaces by an electrochemical anodization method. The oxide film on the surface of the liquid metal is successfully thickened to hundreds of nanometers by electrochemical...
Metal‐oxo clusters have emerged as advanced proton conductors with well‐defined and tunable structures. Nevertheless, the exploitation of metal‐oxo clusters with high and stable proton conductivity over a relatively wide temperature range still remains a great challenge. Herein, three sulfate groups decorated zirconium‐oxo clusters (Zr6, Zr18, and Zr70) as proton conductors are reported, which exhibit...
Sodium‐ion batteries (SIBs) are considered as a promising large‐scale energy storage system owing to the abundant and low‐cost sodium resources. However, their practical application still needs to overcome some problems like slow redox kinetics and poor capacity retention rate. Here, a high‐performance ZnSe/carbon fibers (ZnSe‐CFs) anode is demonstrated with high electrons/Na+ transport efficiency...
The further applications of liquid metals (LMs) are limited by their common shortcoming of silver‐white physical appearance, which deviates from the impose stringent requirements for color and aesthetics. Herein, a concept is proposed for constructing fluorescent core–shell structures based on the components and properties of LMs, and metal halides. The metal halides endow LMs with polychromatic and...
Cancer Phototherapy
The endoplasmic reticulum (ER) plays an important role in protein synthesis, processing and secretion. ER‐targeting phototherapy significantly amplifies ER stress, promotes tumor antigen release, and elicits a robust immunogenic cell death. In article number 2202728 by Weidong Wang, Junping Wang, Shenglin Luo, and co‐workers, a small molecular heptamethine cyanine photosensitizer...
Cancer phototherapy activates immunogenic cell death (ICD) and elicits a systemic antitumor immune response, which is an emerging approach for tumor treatment. Most available photosensitizers require a combination of immune adjuvants or checkpoint inhibitors to trigger antitumor immunity because of the immunosuppressive tumor microenvironment and the limited phototherapeutic effect. A class of tumor‐targeting...
Developing effective electrocatalysts for CO2 reduction (CO2RR) is of critical importance for producing carbon‐neutral fuels. Covalent organic frameworks (COFs) are an ideal platform for constructing catalysts toward CO2RR, because of their controllable skeletons and ordered pores. However, most of these COFs are synthesized from Co‐porphyrins or phthalocyanines‐based monomers, and the available building...
Probing endogenous molecular profiles in living entities is of fundamental significance to decipher biological functions and exploit novel theranostics. Despite programmable nucleic acid‐based aptasensing systems across the breadth of molecular imaging, an aptasensing system enabling in vivo imaging with high sensitivity, accuracy, and adaptability is highly required yet is still in its infancy. Artificial...
The design of high‐performance and durable electrodes for the oxygen evolution reaction (OER) is crucial for pure‐water‐fed anion exchange membrane water electrolysis (AEMWE). In this study, an integrated electrode with vertically aligned ionomer‐incorporated nickel‐iron layered double hydroxide nanosheet arrays, used on one side of the liquid/gas diffusion layer, is fabricated for the OER. Transport...
The morphology regulation of covalent triazine frameworks (CTFs) is a great challenge, which may be due to the difficulty in controlling its morphology by traditional synthesis methods. Herein, a general approach to fabricate morphology controllable CTFs by a mild polycondensation reaction in mixed solvents without any templating agents is reported. As a proof of concept, a type of crystalline CTFs...
Diabetic wound treatment faces significant challenges in clinical settings. Alternative treatment approaches are needed. Continuous bleeding, disordered inflammatory regulation, obstruction of cell proliferation, and disturbance of tissue remodeling are the main characteristics of diabetic wound healing. Hydrogels made of either naturally derived or synthetic materials can potentially be designed...
