An ORR/EO-Cl system using commercial electrodes achieves efficient disinfection at 5 mA/cm 2 . • Cathodic H 2 O 2 consumes anodic free chlorine to generate 1 O 2 as the dominant bactericide. • The system suppresses chlorate and chlorite formation in real medical wastewater. • Multi-level oxidative damage to membranes, DNA, proteins and lipids causes irreversible inactivation. Electrochemical disinfection of chloride-rich medical wastewater faces an inherent trade-off: killing pathogens efficiently while avoiding toxic chlorate and chlorite formation. Here we show that coupling oxygen reduction at a commercial carbon felt cathode with chlorine evolution at a DSA@Ru/Ir anode breaks this trade-off. At 5 mA/cm 2 , cathodic H 2 O 2 rapidly consumes anodic free chlorine, generating singlet oxygen ( 1 O 2 ) as the dominant bactericidal species while suppressing chlorate and chlorite. In real hospital wastewater, chlorate drops from 0.66 to 0.39 mg/L, and the system inactivates 10 7 CFU/mL Escherichia coli in 5 min and Staphylococcus aureus in 10 min-using, the energy consumption was 0.1169 kWh/m 3 and 0.2338 kWh /m 3 , respectively. Quenching, flow cytometry, DNA electrophoresis, protein carbonylation and lipid peroxidation collectively confirm that 1 O 2 -driven oxidative stress causes irreversible membrane, DNA, protein and lipid damage. This work offers a low-energy, commercially viable strategy for electrochemical disinfection of real medical wastewater with intrinsic byproduct suppression.

Functionalized nanosilica is used to carry agrochemical IAA via disulfide bonds. • Under GSH environment, SiO 2 -S-S-IAA exhibits significant redox responsiveness. • The -SH on the surface of SiO 2 can form complexes with various heavy metal ions. • Dual-functional nanocarrier allows sustained IAA release and capture of metal ions. Owing to the low efficiency and lack of target specificity in the application of agrochemicals, e.g., plant growth regulators, the resulting environmental pollution and resource waste have raised enormous concerns over environments and human health. Herein, a redox-responsive nanosilica carrier (SiO 2 -S-S-IAA) was developed for efficient release of 3-indoleacetic acid (IAA), by functionalizing the surface of nanosilica with 3-mercaptopropyltrimethoxysilane (MPTMS), followed by the covalent coupling of IAA via redox-cleavable disulfide bonds. Under the high level of glutathione (GSH) in the plant microenvironment, IAA was released in a controlled way through disulfide bond cleavage, thus achieving redox response. In vitro controlled-release experiments confirmed that the release amount of IAA was significantly higher in the environment of 10 mM GSH, more than 10 folds at pH 5.5. Meanwhile, the thiol groups generated after release could form complexes with various heavy metal ions (Hg 2+ , As 3+ /As 5+ , Cd 2+ , Pb 2+ ), with the highest adsorption efficiency towards Hg 2 + up to 57.95%. More importantly, in planta experiments under cadmium stress have demonstrated that SiO 2 -S-S-IAA not only promoted rice seedling growth but also significantly reduced Cd 2+ accumulation in shoots, effectively inhibiting its transfer to edible parts. This work establishes a dual-functional nanocarrier platform that combines targeted agrochemical delivery with in situ heavy metal immobilization, offering a promising strategy for sustainable and precise crop protection.

Stretchable devices have driven technological advances across diverse fields, including medical sensing, electronic skins, and soft robotics. However, achieving high-performance stretchability often depends on toxic manufacturing, costly syntheses, and petrochemical materials, which conflict with sustainability goals. Here, we present a highly stretchable yet entirely natural biogel fabricated through a simple and environmentally benign process. Despite being derived from low‑cost, food‑grade, and fully biodegradable constituents, our biogel integrates dense intermolecular interactions to achieve a combination of top-performing attributes, including stretchability (∼700%), Young's modulus (∼1.3 MPa), fracture strength (∼2.8 MPa), burst pressure (∼900 mbar), ionic conductivity, and optical transparency. Its mechanical properties remain stable even after 30 days and in subzero temperatures. We showcase its versatility in various applications that demand high stretchability, including deformable sensors for falling object detection, smart electronic fibers for sign language detection, stretchable pneumatic grippers for handling fragile objects, and crawling robots that can serve as plant seed carriers. Our biogel offers a low-cost, sustainable alternative to traditional petrochemical-derived elastomers, opening new possibilities for transient, biodegradable soft devices.

Programmed death-1 (PD-1) is a key biomarker for monitoring therapeutic response and resistance in non-small cell lung cancer (NSCLC) immunotherapy. Achieving highly sensitive, real-time detection of PD-1 is crucial for early prediction of treatment resistance and disease recurrence. However, current methods such as ELISA suffer from limitations in sensitivity, speed, and cost. To address these challenges, we develop a label-free biosensor based on semiconducting single-walled carbon nanotube field-effect transistors (CNT-FETs). The sensing interface is designed by wrapping s-SWCNTs with poly[9-(1-octylnonyl)-9H-carbazole] (PCz), enabling immobilization of anti-PD-1 antibodies via cation-π interactions. XPS analysis confirms antibody immobilization via reversible binding energy shifts in C 1s and N 1s spectra upon salt treatment, consistent with cation-π interactions, further validated by NaCl and imidazole competition assays. Using this strategy, the sensor achieves a detection limit of 8.39 fg/mL for murine PD-1—three orders of magnitude lower than ELISA, along with good specificity and favorable regeneration capability. In human serum, it shows promising performance, with 12 out of 14 NSCLC patient samples (85.7%) exhibiting good linear correlation. With rapid response, low cost, and simple operation, this platform offers a reliable strategy for point-of-care PD-1 monitoring during NSCLC immunotherapy.

Two-dimensional (2D) rare-earth (RE) materials have garnered significant attention due to their unique magnetic properties. Vertically grown 2D materials exhibit significant properties such as high-quality crystals and facile integration. However, due to strong interfacial coupling between materials and the substrate and high nucleation barriers, achieving controlled vertical growth of 2D RE materials remains a challenge. Here, an innovative topochemical transformation strategy is employed to synthesize high-quality vertically grown Eu 2 SO 2 single crystals. The ideal structural framework was provided by the vertical growth of Eu 2 O 3 on the c -sapphire substrate for the subsequent synthesis of a Eu 2 SO 2 single-crystal, effectively mitigating the effects imposed by the sapphire substrate steps and enabling polymer-free transfer. The obtained single-crystal Eu 2 SO 2 exhibits a small rocking curve (FWHM = 0.15°) and an ultralow roughness ( R a = 0.17 nm). Notably, the fabricated Eu 2 SO 2 -based devices exhibit an axial-dependent response, demonstrating a substantial in-plane isotropic magnetoresistance (MR > 50%) and a significant out-of-plane anisotropic magnetoresistance (AMR) ratio of 13.5% accompanied by a large coercivity (1.36 kOe). This work provides a universal approach for preparing vertically grown high-quality 2D RE materials and lays a solid foundation for research into their quantum magnetic properties.

As a promising solution to the global water scarcity crisis, solar interfacial evaporation has been applied to seawater desalination. However, the manufacturing of solar evaporators that simultaneously demonstrate high efficiency and high pollution tolerance remains a challenge. To address this issue, we prepared superhydrophobic cotton fabric with both photocatalytic degradation and photothermal conversion functions. This cotton fabric-assembled evaporator exhibits excellent photothermal conversion performance, achieving an evaporation rate of 1.74 kg·m −2 ·h −1 under 1 Sun illumination. The cotton fabric achieved a 96.4% degradation rate of rhodamine B dye within 1 h under visible light irradiation. Additionally, the cotton fabric exhibited an oil flux of 18420.58 L·m −2 ·h −1 for dichloromethane, with an oil-water separation efficiency exceeding 99%. This work provides an innovative solution for the treatment of complex oily wastewater, which contains salt and dyes.

The built-in field induces charge redistribution and O v formation at electron-poor CoFe-LDH. • O v increases the local electron density of metal active centers, enhancing PMS adsorption and interfacial electron transfer. • Electron-rich α-FeOOH facet favors 1 O 2 generation, whereas O v on the CoFe-LDH side facilitate · O 2 - production. • Toxicological evaluation and parallel dual-electrode experiments confirmed the environmental safety in practical water remediation. Constructing heterojunctions with built-in electric fields for interfacial electron regulation and defect engineering remains a formidable challenge. Herein, an oxygen vacancy (O v )-enriched α-FeOOH/CoFe-LDH heterojunction supported on graphite felt (H-CoFe/GF) was fabricated via an in-situ growth strategy. Theoretical calculations revealed that the α-FeOOH/CoFe-LDH work-function mismatch established a built-in electric field, which drove interfacial charge redistribution and promoted O v formation on the electron-deficient CoFe-LDH side. The resulting O v shifted the d -band center upward to −0.97 eV, enhancing peroxymonosulfate (PMS) adsorption and interfacial electron transfer for simultaneous amoxicillin (AMX) degradation and self-powered monitoring of the degradation process. Reactive oxygen species identification experiments, together with EPR analysis, suggest that singlet oxygen ( 1 O 2 ) and superoxide radicals ( · O 2 - ) were the predominant reactive species in the catalytic process. Thermodynamic analysis indicates that the electron-rich α-FeOOH facet favors 1 O 2 generation with a Gibbs free-energy barrier of 1.35 eV, whereas O v on the CoFe-LDH side lowers the barrier to 0.96 eV and facilitates · O 2 - production. Degradation intermediate identification and toxicological evaluation confirmed the environmental applicability of the system. This work elucidates an integrated defect-engineering mechanism mediated by built-in-electric-field, which couples facet-dependent PMS activation with degradation-correlated self-powered reaction monitoring.

Characterizing exercise-induced fatigue is challenging due to difficulties in monitoring biochemical and electrophysiological signals consistently. While wearable sensors able to monitor both signals are available, they struggle to maintain stable signal acquisition across exercise-rest scenarios because of significant sweat variation. Here we describe the development of a system, FatigueVisual, combining an adaptive sweat-regulating hybrid electronic textile (e-ASRHT) patch with artificial intelligence (AI) analytics to improve fatigue management. The key innovation lies in the precise regulation of the breakthrough pressure of micropores in fabric electrodes and sweat-excreting areas, allowing for accurate sweat management. This design enables efficient enrichment at an ultralow sweat rate (5.0×10 −4 ml cm −2 min −1 ) while rapidly transporting excess sweat at a rate 2533 times the human physiological limit, ensuring stable chemical-electrophysiological sensing from exercise to rest. A cloud-connected AI model, trained on over 200,000 time-resolved observations collected from 10 participants, recognizes six fatigue-related states and provides personalized exercise management via a mobile app. Validation in three participants showed 87.3% agreement with clinical assessments. The system reduced exercise fatigue by 51.8% and accelerated recovery by 48 h compared with the control group. In practice, FatigueVisual may enable intelligent sports health management.

Sustainable water purification demands oxidation processes
that
are both highly efficient and chemically self-sufficient. Electrochemical
advanced oxidation is inherently green, yet the reactivity of hydroxyl
radicals (*OH) is typically confined to the electrode interface, limiting
overall treatment efficiency. Here we report the discovery of a putative
nonradical hydrotrioxide species, – O 3 SOOOH, generated in situ by coupling surface-bound
*OH with asymmetric peroxides ( − O 3 SOOH)
on commercial Pt electrodes. This mediator relays oxidative equivalents
from the anode into the bulk solution without reagent consumption,
increasing pollutant-degradation rates by 231–856%. Operando
spectroscopy, isotope tracing, differential electrochemical mass spectrometry,
and density functional theory calculations reveal a pseudo-oxidative,
two-electron oxygen-transfer pathway distinct from radical or direct-electron-transfer
routes. The putative – O 3 SOOOH exhibits
exceptional product selectivity while maintaining a high oxidative
potential. The process proceeds under mild potentials, resists interference
from common anions, and can be integrated with reverse-osmosis membranes
for continuous, zero-reagent purification. The discovery of hydrotrioxide-mediated
oxidation establishes a scalable and low-carbon electrochemical platform
for sustainable water treatment.

Scandium (Sc), as a critical rare earth element (REE),
holds significant
application value in advanced manufacturing, energy materials, catalysis,
and other fields. However, due to the common coexistence of Sc with
light and heavy REEs, which exhibit high similarities in ionic radius,
valence state, and coordination chemistry, conventional spectrophotometric
methods suffer from poor selectivity, making accurate quantification
of Sc 3+ in complex matrices difficult. In this study, we
present a label-free ion sensing platform based on silicon nanowire-modified
glass micropipettes (SiNWs@GMP). By incorporating the Sc-1 DNA recognition
unit, the platform achieves highly sensitive and selective detection
of Sc 3+ as well as sequential discrimination between light
and heavy REEs. The three-dimensional porous SiNWs network inside
the GMP provides abundant immobilization sites for Sc-1 DNA. Under
an applied electric field, the specific binding between Sc 3+ and Sc-1 DNA modulates ion transport within the channel, generating
measurable changes in ionic current. The constructed sensor exhibits
a detection concentration range for Sc 3+ from 1 pM to 10 5 pM and a detection limit for Sc 3+ as low as 1
pM, which can effectively distinguish Sc 3+ from light REEs.
Meanwhile, the use of EDTA to selectively suppress interference from
coexisting heavy REEs further verifies the high selectivity of Sc-1
DNA. This platform demonstrates good stability, repeatability, and
reliability in aqueous environments, highlighting its potential for
applications in environmental monitoring and REEs analysis.

Endogenous signaling molecules are essential for coordinated
wound
healing, yet current donor-based dressings typically provide only
single-mediator delivery with limited release duration. Here, a multifunctional
hydrogel dressing, HEVCTM, is developed by free radical copolymerization
of N -hydroxyethyl acrylamide (HEAA) with a hydrogen
peroxide (H 2 O 2 ) releasing donor (VIM-CAT) and
a hydrogen sulfide (H 2 S) releasing donor (TBA-MA). The
hydrogel enables temporally programmed release, with rapid H 2 O 2 delivery within 24 h for early stage antibacterial
action and sustained H 2 S release for up to 7 days to alleviate
inflammation and promote angiogenesis during later healing stages.
HEVCTM exhibits potent antibacterial activity against Escherichia coli (99.6%) and Staphylococcus aureus (99.97%), significantly enhances macrophage
M2 polarization (52.4%), and shows favorable antioxidant, hemostatic,
adhesive, and pro-angiogenic properties. Moreover, in an infected
mouse wound model, HEVCTM significantly accelerated wound healing
and promoted tissue regeneration. This work provides a bioactive hydrogel
platform that matches the dynamic requirements of wound healing and
effectively accelerates tissue repair.

Paper-based analytical devices (PADs) have revolutionized environmental monitoring, food safety and disease diagnosis due to their inherent portability, simplicity, and cost-efficiency. Among these, distance-based PADs enable instrument-free quantitative detection by translating target concentration into measurable flow distance. Stimuli-responsive hydrogels, whose viscosity can be altered by target-triggered sol-gel transitions, are widely used in distance-based PADs, among which click-chemistry hydrogels stand out by virtue of their efficient and stable covalent bonding. Such stable covalent networks provide click hydrogels with strong anti-swelling and anti-degradation properties, crucial for reliable performance in on-site environments. In this study, we present a novel distance-based PAD approach that integrates target-induced click hydrogels, establishing a highly stable, versatile, and sensitive platform for multi-analyte detection. This innovative PAD makes use of copper-catalyzed azide-alkyne cycloaddition click chemistry to craft hydrogels from polyethylene glycol derivatives. Notably, specific target analytes like Cu²⁺, ascorbic acid, alkaline phosphatase, and pyrophosphate finely modulate the hydrogel crosslinking degree, causing noticeable changes in its viscosity. These viscosity variations are then translated into measurable flow distances on pH test papers, providing a direct and quantitative visual readout without the need for complex instrumentation or extensive operation. The entire detection process, from sample loading to result readout, can be accomplished within approximately 5 min, demonstrating the rapid analysis capability of this approach. This work offers stable, rapid, sensitive, and cost-effective multi-target detection, significantly advancing instrument-free PAD technology and expanding the scope of versatile analyte detection.
