Activating the stimulator of the interferon gene (STING) is a promising immunotherapeutic strategy for converting “cold” tumor microenvironment into “hot” one to achieve better immunotherapy for malignant tumors. Herein, a manganese‐based nanotransformer is presented, consisting of manganese carbonyl and cyanine dye, for MRI/NIR‐II dual‐modality imaging‐guided multifunctional carbon monoxide (CO)...
Organic photomechanical molecular crystals are promising candidates for photoactuators, which have potential applications as smart materials in various fields. However, it is still challenging to fabricate photomechanical molecular crystals with flexibility because most of the molecular crystals are brittle and the mechanism of flexible crystals remains controversial. Here, a plastically flexible...
Practical applications of lithium‐sulfur (Li‐S) batteries have been hindered by sluggish reaction kinetics and severe capacity decay during charge‐discharge cycling due to the notorious shuttle effect of polysulfide and the unfavored deposition and dissolution of Li2S. Herein, to address these issues, a double‐defect engineering strategy is developed for preparing Co‐doped FeP catalyst containing...
Lithium‐Sulfur Batteries
In article number 2301545, Hao Sun, Shaochun Tang, and co‐workers report a novel dual‐defect catalyst comprised of Co‐doped FeP with P vacancies on MXene (CoD‐FePv@MXene), which serves as both deposition regulator and redox accelerator for Li2S electrochemistry. The P vacancies deliver more LiPSs adsorption/active sites for accelerating Li2S nucleation, and the Co doping produces...
Precise timing of macrophage polarization plays a pivotal role in immunomodulation of tissue regeneration, yet most studies mainly focus on M2 macrophages for their anti‐inflammatory and regenerative effects while the essential proinflammatory role of the M1 phenotype on the early inflammation stage is largely underestimated. Herein, a superparamagnetic hydrogel capable of timely controlling macrophage...
Highly efficient and mechanically durable photothermal materials are urgently needed for solar harvesting, but their development still remains challenging. Here, inspired by the hierarchically oriented architecture of natural spider silk, an ultrarobust liquid metals (LMs)/polymer composite is presented via dynamic crosslinking based on the unique mechanical deformable characteristic of LMs. Dynamically...
Artificial intelligence vision systems (AIVSs) with information sensing, processing, and storage functions are increasingly gaining attention in the science and technology community. Although synapse phototransistor (SPT) is one of the essential components in AIVSs, solution‐processed large‐area photonic synapses that can detect and recognize multi‐wavelength light are highly desirable. One of the...
Carbon‐based nanomaterials have been widely utilized in catalysis and energy‐related fields due to their fascinating properties. However, the controllable synthesis of porous carbon with refined morphology is still a formidable challenge due to inevitable aggregation/fusion of resulted carbon particles during the high‐temperature synthetic process. Herein, a hierarchically oriented carbon‐structured...
The eukaryotic cell is a smart compartment containing an outer permeable membrane, a cytoskeleton, and functional organelles, presenting part structures for life. The integration of membrane‐containing artificial organelles (=polymersomes) into a large microcompartment is a key step towards the establishment of exquisite cellular biomimetics with different membrane properties. Herein, an efficient...
Different membrane characteristics regulate biological pathways in eukaryotic cells. In article number 2005749, Xin Huang, Dietmar Appelhans, and co‐workers demonstrate the function of orthogonal‐responsive membranes of eukaryotic cell biomimetics for the modulation of protein transport.
Cells, sophisticated membrane‐bound units that contain the fundamental molecules of life, provide a precious library for inspiration and motivation for both society and academia. Scientists from various disciplines have made great endeavors toward the understanding of the cellular evolution by engineering artificial counterparts (protocells) that mimic or initiate structural or functional cellular...
Drug delivery strategies possessing selectivity for cancer cells are eagerly needed in therapy of metastatic breast cancer. In this study, the chemotherapeutic agent, docetaxel (DTX), is conjugated onto heparan sulfate (HS). Aspirin (ASP), which has the activity of anti‐metastasis and enhancing T cells infiltration in tumors, is encapsulated into the HS‐DTX micelle. Then the cationic polyethyleneimine...
As a model protocell, the membrane‐free coacervate microdroplet is widely utilized in functional studies to provide insights into the physicochemical properties of the cell and to engineer cytomimetic soft technologies; however, the lack of a discrete membrane contributes to its instability and limits further application. Herein, a strategy is developed to fabricate a hybrid protocell based on the...
Controlled membrane fusion of proteinosome‐based protocells is achieved via a hydrogel‐mediated process involving dynamic covalent binding, self‐healing, and membrane reconfiguration at the contact interface. The rate of proteinosome fusion is dependent on dynamic Schiff base covalent interchange, and is accelerated in the presence of encapsulated glucose oxidase and glucose, or inhibited with cinnamyl...
Visible light communication (VLC) simultaneously provides illumination and communication via light emitting diodes (LEDs). Keeping a low bit error rate is essential to communication quality, and holding a stable brightness level is pivotal for illumination function. For the first time, a piezo‐phototronic effect controlled visible light communication (PVLC) system based on InGaN/GaN multiquantum wells...
