In this work we investigate novel, agarose-based polymer electrolyte that is modified by magnetic NiO nanoparticles for solid-state dye-sensitized solar cells (DSSCs) applications. After proper treatment under an external magnetic field , the agarose electrolyte exhibits increased ionic conductivity and better penetration into the mesoporous TiO 2 photoanode film, which improves the power conversion efficiency of the DSSCs. Electrochemical impedance spectroscopy measurement is also performed to analyze the magnetic field effect on cell performance. After applying proper magnetic filed intensity, the recombination resistance and redox transport resistance in the devices are improved. This method can be possibly applied to other solid-state electrolyte materials to improve their performance and can lead to more efficient DSSCs.

Motivated by gas-accessible thin liquid films in lung alveoli, we develop gas marble-film reactors in which particle-stabilized bubbles confine an ultrathin freestanding liquid film within a jammed solid shell. Hexagonal PET (poly(ethylene terephthalate)) plates, in addition to conventional spherical particles, generate faceted gas marbles with planar film regions that improve optical access. We quantify the pressure limits of microsphere- and plate-stabilized shells during inflation and deflation, and describe their response using a capillary–granular framework. In this framework, inflation rupture is governed by capillary breakthrough at particle-defined throats, whereas deflation collapse reflects the combined resistance of capillarity and interparticle jamming. The mechanically defined films then serve as gas-accessible interfacial reactors in two proof-of-concept demonstrations. In a Tollens reaction, aerosolized glucose delivery through the external gas phase localizes silver reduction to liquid-wetted regions of the particle shell, producing spatially patterned silver-deposited microspheres. In biological assays, plate-stabilized shells provide flat observation windows for monitoring aerobic E. coli growth and its inhibition by levofloxacin. These results establish gas marbles as programmable colloidal film reactors whose structure, pressure stability, and interfacial function can be coupled through particle geometry and capillary jamming.

Microcystin contamination caused by harmful cyanobacterial blooms is a growing global challenge for water safety. Here we reported a self-assembled living microreactor that encapsulated microcystin-degrading bacteria within a biochar-reinforced double-network hydrogel, enabling integrated molecular sieving, adsorption, and enzymatic degradation. The system exhibited size- and charge-selective removal of microcystin over coexisting organic matters, while maintaining high degradation efficiency under harsh stress conditions, including pH (5−9), inorganic ions (10−200 mg/L), and natural organic matters (5−20 mg/L). The microreactor demonstrated excellent mechanical stability, negligible cell leakage, and high bioactivity, and achieved nearly complete removal of microcystin-LR during five repeated operation cycles and continuous biofiltration in environmental water, confirming its scalable application potential. Mechanistic investigations revealed a cascade process involving shell-confined molecular sieving, adsorption-mediated toxin enrichment on biochar, and localized biodegradation within the living core. This work establishes a generalizable design paradigm for programmable living materials, offering new opportunities for selective biodegradation and remediation in complex aqueous systems.

A monolithic porous carbon is prepared from agar/melamine sponge composite hydrogel. • The prepared porous carbon is compressible. • The prepared monolithic carbon exhibits outstanding capacitive performance. • The proposed synthetic strategy offers an effective route to monolithic porous carbons. High-performance electrode materials are crucial for advancing supercapacitor technology. Herein, a monolithic porous carbon material is synthesized using an agar/melamine sponge (AG/MS) composite hydrogel as the precursor. The composite hydrogel is fabricated by exploiting the unique gelation behavior of agar. Through subsequent freeze-drying and high-temperature carbonization, a self-standing porous carbon monolith is obtained. The pore structure of the agar/melamine sponge derived carbon is modulated via KOH activation. The resulting monolithic porous carbon (denoted as KAMC) features a hierarchically porous structure and a substantial specific surface area of 1570.3 m 2 g −1 . Electrochemical evaluation in a 3 M KOH electrolyte reveals that the KAMC electrode delivers a high specific capacitance of 364.2 F g −1 at 1 A g −1 . Moreover, it exhibits exceptional rate performance, retaining 92.3% of its capacitance when the current density is increased to 10 A g −1 . A symmetric quasi-solid-state supercapacitor assembled with two KAMC electrodes achieves an energy density of 9.80 Wh kg −1 , demonstrating the material's potential for high-performance energy storage applications. This work provides a straightforward and effective approach for preparing monolithic carbon-based electrode suitable for advanced supercapacitors.

Fresh shrimp, a protein-rich aquatic product, is prone to microbial spoilage during storage and transportation, posing risks to human health. Since spoilage degree cannot be identified by the naked eye, responsive smart packaging is urgently needed for real-time freshness monitoring of fresh shrimp. Herein, pH-responsive (copper sodium chlorophyllin-alizarin)/fish skin gelatin nanofiber-based hydrogel membranes were fabricated by embedding copper sodium chlorophyllin (CSC) and alizarin (ALI) in fish skin gelatin (FSG) substrate via electrospinning technology, followed by crosslinking via Maillard reaction and subsequent hydrogel formation through water absorption-swelling mechanism. Their structure, physical properties, pH-responsive behavior and application in fresh shrimp packaging were systematically investigated. The FAC-3 hydrogel membranes, embedded with 0.294 wt% CSC-ALI, exhibited a well-defined three-dimensional porous structure and a swelling rate of 434.93 ± 18.83%. The FAC-3 displayed distinct color changes under varying pH conditions, along with excellent sensitivity and color reversibility upon exposure to ammonia/acetic acid vapors. Comprehensive evaluations of the sensory quality, pH value, packaging membrane color changes, total colony count and total volatile basic nitrogen (TVB-N) of fresh shrimp demonstrated that FAC-3 exhibited outstanding indicative and monitoring performance for refrigerated shrimp. This work offers new insights for the development of aquatic product freshness-indicating packaging.

Nanofillers usually suppress the self-healing capability of the matrix, because they restrict polymer-chain mobility. This study aims to develop polyurethane nanocomposites with integrated self-healing and antimicrobial properties by simultaneously introducing non-covalent interactions. Initially, chemical modification was used to introduce quaternary ammonium and amphiphilic ionic groups onto cellulose nanofibers, producing amphiphilic nanocellulose (Am-CNF). Subsequently, Am-CNF was mixed with a self-healing ionic polyurethane (IPU) in different proportions using a solution-mixing method to create a series of self-healing antimicrobial APUs. The results indicate that the incorporation of Am-CNF didn’t deteriorate the self-healing behavior and endowed the composites with attractive antibacterial properties through electrostatic interactions with bacteria. At room temperature, the self-healing of the composites is even faster than that of pure IPU, as observed by optical microscopy and 3D confocal microscopy. The developed APUs demonstrated rapid self-healing capabilities and showed up to 99.9% antimicrobial efficacy against both Gram-positive and Gram-negative bacteria. Cellular and animal tests further validated the biosafety of these samples and indicated their potential as medical or packaging materials.

The transmembrane aquaporin (AQP) protein with high permeability and selectivity have received substantial attention for preparing biomimetic membranes. However, the biological activity and loading mass of AQP in membranes are facing challenges. Here, AQP was expressed in E. coli cell membranes via genetic engineering, and then the cell membranes containing AQP were used to develop a biomimetic nanofiltration (NF) membrane, thereby maintaining the biological activity and increasing the loading mass of AQP. The membrane with high water permeance (66.5 L m -2 h -1 bar -1 ) exhibited a rejection sodium sulfate of 75.5% and high brilliant blue R rejection (99.8%), confirming the precise sieving ability of AQP. The membrane not only showed the typical sieving mechanism of the negatively charged NF membranes, but AQP possessed specialized water channels. This work provides some insights into the construction of high-performance biomimetic membranes using transmembrane proteins with high perm-selectivity and numerous choices in nature.

Rare-earth nanoparticles represent a promising class of NIR-IIc emitters for deep-tissue bioimaging beyond 1700 nm; however, the practical application remains limited by their suboptimal luminescence brightness and the low quantum efficiency (QE) of current detectors. Here we report a dual-sensitizer rare-earth nanoprobe (YbEr:Tm) that strategically steers Er-Er energy migration into the favorable 4 I 13/2 → 4 I 13/2 channel, yielding a 43.5-fold enhancement of Tm 3+ emission in the NIR-IIc window. The resulting YbEr:Tm nanoprobes afford 180 µm spatial resolution through 1.5 cm of thoracic muscle, even under the constraints of a low-QE extended-range InGaAs detector. Building on this brightness, we achieve the first dynamic multiplexed NIR-IIc in vivo bioimaging by exploiting the lifetime disparity between rare-earth nanoprobes and PbS quantum dots. Furthermore, an implantable three-plex NIR-IIc optical cipher is devised, in which distinct nanoprobes with orthogonal lifetimes and spectral profiles enable information encryption within subcutaneous tissue and real-time, noninvasive retrieval.

While combination therapies generally exhibit superior therapeutic outcomes compared to single-modality treatments, current photodynamic–chemodynamic (PDT/CDT) combination strategies remain limited by two major factors: (i) the restricted tissue penetration depth of light and (ii) the insufficient endogenous hydrogen peroxide (H2O2) concentration within the tumor microenvironment (TME), both of which compromise therapeutic efficacy. To overcome these obstacles, we developed an innovative hybrid nanorobot (EcN + UCNPs@mSiO2–MnO2–ZnPc) that integrates engineered Escherichia coli Nissle 1917 (EcN) with orthogonally emissive upconversion nanoparticles (C@3S). Specifically, MnO2 decomposes into Mn2+ under acidic TME conditions, subsequently catalyzing the conversion of H2O2 into cytotoxic hydroxyl radicals (˙OH) and oxygen, which exhibits dual effects of tumor cell eradication and hypoxia alleviation. Meanwhile, C@3S transforms 980 nm laser radiation into blue-violet emission, activating the EcN that preferentially colonizes tumor regions and overexpresses respiratory chain enzyme II (NDH-II), thereby replenishing H2O2 in situ and sustaining chemodynamic therapy (CDT). Additionally, zinc phthalocyanine (ZnPc) is excited by the 808 nm-converted red emission to generate singlet oxygen (1O2), further enhancing reactive oxygen species (ROS) accumulation and amplifying oxidative stress in tumor cells. Collectively, our findings demonstrate significant tumor growth inhibition through this self-amplifying ROS-generation mechanism. This multifunctional hybrid nanorobot offers a promising platform for precision cancer therapy with spatiotemporal controllability.

Endometritis, a common gynecological disease caused by ascending bacterial infection, is a leading cause of infertility. Currently, the clinical treatment relies primarily on antibiotic therapy, administered via intravenous injection, oral administration, or local delivery (e.g., intrauterine infusion). Nevertheless, intravenous injection aggravates hepatic and renal burdens, whereas oral administration elicits gastrointestinal reactions; intrauterine infusion suffers from drug leakage from the uterus due to gravity. Therefore, we developed mucoadhesive doxycycline hydrochloride-loaded air microbubbles (Mad-Doxy-MBs) for intrauterine infusion therapy of endometritis to overcome these limitations. The results showed that Mad-Doxy-MBs exhibited an ultrasound contrast-enhancement property so that they could be tracked by clinicians under ultrasound to achieve their precise localization on the endometrium when infused transvaginally. Subsequently, Mad-Doxy-MBs adhered to the endometrial surface and continuously released Doxy, exhibiting robust bactericidal and anti-inflammatory capacities. Compared with daily oral Doxy administration, two once-weekly intrauterine infusions of Mad-Doxy-MBs achieved superior therapeutic efficacy against endometritis while exhibiting markedly lower gastrointestinal toxicity. This drug delivery platform that integrates the properties of ultrasound visualization, mucoadhesion, and sustained drug release offers a clinically translatable strategy for intrauterine infusion therapy of endometritis and opens new avenues for precise and long-term drug delivery in other luminal diseases.

Sponge-based preservative packaging is an emerging approach to mitigate mechanical damage to fruits and vegetables during transportation, storage, and retail. However, conventional polyurethane sponges generally lack durable antibacterial activity and are neither biodegradable nor readily recyclable. Herein, to address these limitations, silver nanoparticles immobilized on TEMPO-oxidized cellulose nanofibers (TCNF@AgNPs) were incorporated into a quaternized chitin matrix to construct a synergistic antibacterial composite sponge (QCH/TCNF@AgNPs) for fruit preservation. The composite sponge exhibited strong antibacterial efficacy againstEscherichia coliandStaphylococcus aureus, together with a low cumulative release of silver species of 2.49% after 336 h. In addition, the sponge showed >50% mass loss after 36 days in lysozyme solution, indicating good enzymatic degradability. Cytocompatibility assays further confirmed favorable biocompatibility and biosafety. Notably, the composite sponge provided satisfactory preservation performance for fresh strawberries. Overall, this work demonstrates the potential of QCH/TCNF@AgNPs as a biodegradable antibacterial packaging sponge for fruit preservation.

Emerging evidence underscores biophysical characteristics of cancer cells as key modulators of cancer progression and metastasis. Herein, we reported a cell-mechanophenotyping screening microfluidic chip (termed LesM) for the high-efficient capture of circulating tumor cells (CTCs) and evaluation of single-cell deformation to reveal the hematogenous metastatic potential of bacteria-infected breast cancer. LesM employs L-shaped traps to capture single cells, leveraging bacteria-infected CTCs with cytoskeletal reorganization traverse narrowed channels while rigid native cells are retained. The platform demonstrates an average single-cell capture efficiency of 95.42% and specificity of 85.34% in discriminating infected versus non-infected breast cancer cells, validated through parallel in vivo metastatic assays. LesM enables high-throughput sensing up to 10,240 cells of mechanical signatures and microbial cargo, correlating with metastatic risk and antibiotic response. By bridging biomechanics and intratumoral microbiota detection, LesM offers a transformative liquid biopsy tool for predicting distant metastasis and guiding antimicrobial therapies in bacteria-infected breast cancers.
