The selective quantification of copper ions (Cu2+) in biosamples holds great importance for disease diagnosis, treatment, and prognosis since the Cu2+ level is closely associated with the physiological state of the human body. While it remains a long‐term challenge due to the extremely low level of free Cu2+ and the potential interference by the complex matrices. Here, a pore‐engineered hydrogen‐bonded...
Gut microbiota function has numerous effects on humans and the diet humans consume has emerged as a pivotal determinant of gut microbiota function. Here, a new concept that gut microbiota can be trained by diet‐derived exosome‐like nanoparticles (ELNs) to release healthy outer membrane vesicles (OMVs) is introduced. Specifically, OMVs released from garlic ELN (GaELNs) trained human gut Akkermansia muciniphila...
The rapid, simultaneous, and accurate identification of multiple non‐nucleic acid targets in clinical or food samples at room temperature is essential for public health. Argonautes (Agos) are guided, programmable, target‐activated, next‐generation nucleic acid endonucleases that could realize one‐pot and multiplexed detection using a single enzyme, which cannot be achieved with CRISPR/Cas. However,...
Organic compounds are regarded as important candidates for potassium‐ion batteries (KIBs) due to their light elements, controllable polymerization, and tunable functional groups. However, intrinsic drawbacks largely restrict their application, including possible solubility in electrolytes, poor conductivity, and low diffusion coefficients. To address these issues, an ultrathin layered pyrazine/carbonyl‐rich...
Recently, nanozyme‐based photothermal‐catalytic therapy has emerged as a promising strategy for antitumor treatment. Extensive research has focused on optimizing the catalytic activity and photothermal conversion performance of nanozymes through size, morphology, and surface property regulations. However, the biological effects of nanozymes, such as cellular uptake and cytotoxicity, resulting from...
Selective photocatalytic production of high‐value acetaldehyde concurrently with H2 from bioethanol is an appealing approach to meet the urgent environment and energy issues. However, the difficult ethanol dehydrogenation and insufficient active sites for proton reduction within the catalysts, and the long spatial distance between these two sites always restrict their catalytic activity. Here, guided...
Triple‐negative breast cancer (TNBC) is highly malignant and prone to recurrence and metastasis. Patients with TNBC have limited therapeutic options, often resulting in poor prognosis. Some new treatments for TNBC have been considered in the past decade, such as immunotherapy, photothermal therapy (PTT), and ferroptosis therapy, that allow the rapid and minimally invasive ablation of cancer. However,...
Metal‐organic frameworks (MOFs) are high‐performance adsorbents for atmospheric water harvesting but have poor water‐desorption ability, requiring excess energy input to release the trapped water. Addressing this issue, a Janus‐structured adsorbent with functional asymmetry is presented. The material exhibits contrasting functionalities on either face – a hygroscopic face interfaced with a photothermal...
Helicobacter pylori (H. pylori) infection presents increasing challenges to antibiotic therapies in limited penetration through gastric mucus, multi‐drug resistance (MDR), biofilm formation, and intestinal microflora dysbiosis. To address these problems, herein, a mucus‐penetrating phototherapeutic nanomedicine (RLs@T780TG) against MDR H. pylori infection is engineered. The RLs@T780TG is assembled...
Self‐Wrinkling Polymer Films
In article number 2311679, Han‐Yu Hsueh and co‐workers were inspired by the superglue fuming method for fingerprint collection and developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. The technique can be easily applied to architectures with complex outer morphologies and inner surfaces and has...

In article number 2308731, Bing Liu, Chun Xu, Lin‐Lin Bu, and co‐workers explore the innovative use of nanoparticles for targeted drug delivery to lymph nodes, aiming to activate the immune system in the battle against cancer. The image interprets the physiological process of nanoparticles targeting lymph nodes for drug delivery as an approach in immunotherapy.
Polyacrylonitrile/Boric acid/Melamine/the delaminated BN nanosheets electrospun fiber membrane (PB3N1BN) with excellent mechanical property, high thermal stability, superior flame‐retardant performance, and good wettability are fabricated by electrospinning PAN/DMF/H3BO3/C3H6N6/ the delaminated BN nanosheets (BNNSs) homogeneous viscous suspension and followed by a heating treatment. BNNSs are obtained...
Inspired by the superglue fuming method for fingerprint collection, this study developed a novel interfacial‐fuming‐induced surface instability process to generate wrinkled patterns on polymeric substrates. High‐electronegativity groups are introduced on the substrate surface to initiate the polymerization of monomer vapors, such as ethyl cyanoacrylate, which results in the formation of a stiff poly(ethyl...
In this study, germanium arsenide (GeAs) is investigated as a promising nanomaterial for application in triboelectric nanogenerators and green energy harvesting. The mechanical and electrical properties of mechanically exfoliated GeAs on silica substrates are evaluated through friction force microscopy and Kelvin probe force microscopy, respectively. First, it is observed that the surface potential/work...
VO2 material, as a promising intercalation host, is widely investigated not only in aqueous lithium‐ion batteries, but also in aqueous zinc‐ion batteries (AZIBs) owing to its stable tunnel‐like framework and multivalence of vanadium. Different from lithium‐ion storage, VO2 can provide higher capacity when storing zinc ions, even exceeding its theoretical capacity (323 mAh g−1), but the specific reason...
The capacity to self‐detect and locate damage to underwater infrastructure in emergencies is vital, as materials and technologies that securely facilitate energy and information transmission are crucial in several fields. Herein, the development of a multifunctional supramolecular ionogel (SIG) and SIG‐based devices for use in detecting and locating damage to underwater infrastructure is reported...
Achieving a balance between H‐atom adsorption and binding with H2 desorption is crucial for catalyzing hydrogen evolution reaction (HER). In this study, the feasibility of designing and implementing built‐in opposite electric fields (OEF) is demonstrated to enable optimal H atom adsorption and H2 desorption using the Ni3(BO3)2/Ni5P4 heterostructure as an example. Through density functional theory...
Electron transport layers (ETLs) generally contain polar groups for enhancing performance and reducing the work function. Nevertheless, the polar group with high surface energy may cause inferior interfacial compatibility, which challenges the ETLs to balance stability and performance. Here, two conjugated small molecules of ETLs with low surface energy siloxane, namely PDI‐Si and PDIN‐Si, are synthesized...
Oxygen evolution reaction (OER) is the half‐reaction in zinc–air batteries and water splitting. Developing highly efficient catalysts toward OER is a challenge due to the difficulty of removing four electrons from two water molecules. Covalent organic frameworks (COFs) provide the new chance to construct the highly active catalysts for OER, because they have controlled skeletons, porosities, and well‐defined...
Immunotherapy has emerged as a potent strategy in cancer treatment, with many approved drugs and modalities in the development stages.
