As crucial biomarkers, the rapid and sensitive detection of dopamine (DA) and uric acid (UA) is essential for disease prevention and diagnosis. In this study, MoS 2 /MoO 2 heteronanorod modified N-doped porous carbon nanofiber (N-PCNFs@MoS 2 /MoO 2 ) sensing electrodes for the simultaneous detection of DA and UA were fabricated by electrostatic spinning coupled with vulcanization reaction. The carbonization treatment of the ZIF-8/PAN precursor endows material with hierarchical pores and a highly conductive network, which significantly increases the specific surface area and active sites and provides a fast electron transport channel for electrochemical reactions. Moreover, the synergistic effect of MoS 2 /MoO 2 optimizes the ion transport pathway and further enhances the electrocatalytic performance. Experimental results show that the electrode exhibites excellent performance for the simultaneous detection of DA and UA. The linear range for DA detection is 0.5–35 µM with a limit of detection (LOD) of 0.038 µM (S/ N = 3), while UA shows a two-segment linear response with linear ranges of 1–20 µM and 20–110 µM, respectively, and a LOD of 0.245 µM (S/ N = 3). This electrode is capable of realizing the simultaneous detection of DA and UA in human serum, showing a broad application prospect in the field of biosensing.

Conductive hydrogels represent a pivotal advancement for next-generation wearable electronics. However, simultaneously optimizing mechanical robustness, interfacial adhesion, and electromechanical sensitivity remains a significant challenge. In this study, a multifunctional poly(vinyl alcohol)/chitosan/multi-walled carbon nanotube (PCM) composite hydrogel was developed via a facile freeze-thaw strategy. The resulting PCM hydrogel exhibits reliable adhesive strength (12.1 kPa on porcine skin) with over 70% retention after 10 cyclic attachment-detachment tests. Notably, the hydrogel possesses a high electrical conductivity of 13.2 mS/cm, enabling superior sensing performance with a Gauge Factor (GF) of 5.72 under large strains and excellent durability over 500 cycles. Real-time monitoring of human joint motions (e.g., wrist, finger, and elbow) confirms its rapid response and high signal fidelity. These results underscore the potential of PCM hydrogels as a robust and high-performance interface for sophisticated human-machine interaction and sports health monitoring.

Blends of soy proteins isolate (SPI) and insoluble dietary fiber (IDF) are promising due to their ability to produce fibrous products resembling meat texture. In this study, model blends of SPI-IDF (SPI: IDF = 90:10, based on dry mass) with varying proportions of soluble (SSPI) and insoluble SPI (ISPI) were produced through high-moisture extrusion. The rheological behaviors of the SPI-IDF blends, as well as the morphology and mechanical properties of the extrudates, were investigated. The results showed that the ISS-40 extrudate (ISPI: SSPI = 4:0) exhibited pronounced fibrous structures with superior mechanical anisotropy. This was attributed to the even distribution of numerous small-sized voids or honeycomb areas, which were deformed along the extrusion flow direction. In contrast, ISS-04 extrudate (ISPI: SSPI = 0:4) exhibited a gel-like structure with the coalescence of IDF domains. These morphological and mechanical differences were attributed to the viscoelastic properties of protein matrix, which affected the distribution of dispersed IDF domains. Thus, these insights into the interactions between the continuous and dispersed phases in SPI-IDF blends provide guidance for developing meat analogue products with desired textural properties.

Two-dimensional (2D) materials hold promise for miniaturized photodetectors. With ample exciton resonances, the photodetection range of transition metal dichalcogenides (TMDCs) can be further extended to long wavelengths on a large scale by two-photon absorption (TPA), breaking the limit of their bandgaps. However, the conversion efficiency of TPA usually remains low despite resonant nonlinear optical effects. Here, we present a plasmonic metasurface-enhanced 2D TMDC photodetector by means of high-order multipoles with anapole states, as well as quasi-bound states in the continuum, operating efficiently in the near-infrared second (NIR-Ⅱ) window at room temperature. The optical response of the MoS 2 /WSe 2 heterostructure is simultaneously enhanced by the interlayer exciton resonances and by the hot carrier injection from the plasmonic metasurface. By optimizing the metasurface design, the responsivity can reach 1.35 A/W at 1550 nm, which is ~5 × 10 4 times larger than that of a MoS 2 /WSe 2 heterostructure on SiO 2 /Si substrate. Furthermore, the broken mirror symmetry of the structure enables a chiral photoelectric response with discrimination ratios up to 7.2. Our study offers a promising platform for applications in NIR-Ⅱ bio-imaging, telecommunication, and on-chip spectroscopic sensing.

Titanium carbide MXene flakes hold great promise for system-level MXene-based electronics (MXetronics) due to their outstanding electrical conductivity and diverse functional properties. However, the weak MXene interlayer bonding often causes film fracturing under mechanical strain, ultimately leading to device failure, manifested as unstable operation, inaccurate data transmission, and potential electrical disconnection. Here, we present strain-invariant, omnidirectionally stretchable MXetronics (sos-MXetronics) through hierarchical stiffness microgrid engineering. This strategy synergistically integrates patterned elastiff regions and modulus-buffered interconnects, effectively preventing performance shifts in sos-MXetronics. This circular sos-MXetronics with a radius of 3.3 cm integrates a near-field communication (NFC) antenna, eight micro-supercapacitors (MSCs), three resistive sensors, and interconnected conductive networks, demonstrating exceptional strain invariance with 95–98% performance retention even under 40% strain. With the capability to minimize motion-induced artifacts, the system ensures accurate blood pressure (BP) monitoring without electrical disconnection, even during wrist deformations. This breakthrough not only marks a significant step toward the practical application of MXene in omnidirectional stretchable MXetronics, but also paves the way for reliable, high-performance electronics based on two-dimensional materials for next-generation healthcare monitoring systems that seamlessly integrate with the human body under real-world conditions.

A series of polypyrrole oligomers (PPOs)—MPMH, MPEH, MPTH, and MPCH—were synthesized via solution polycondensation of N-methylpyrrole and para-substituted benzaldehydes to systematically explore substituent effects on their structural, optical, and electrochemical properties. MPTH showed enhanced crystallinity via π–π stacking, while MPCH formed a honeycomb-like porous structure. Optically, MPCH exhibited red-shifted excitation and emission (394/513 nm) due to a push–pull effect. The oligomers emitted violet (MPMH, MPEH), blue (MPTH), and green (MPCH) fluorescence, respectively. Electrochemically, substituents fine-tuned HOMO levels, giving band gaps of 2.0–2.4 eV suitable for visible-light emission. This study clarifies the role of substituents in modulating optoelectronic behavior, supporting the design of functional polymers for electronics and sensing. Graphical abstract

A new process for the controlled-synthesis of large surface area mesoporous silica nanoparticles (MSNs) from the unique (NH 4 ) 2 SiF 6 -NH 4 F solution produced from coal fly ash was developed using template assisted rapid chemical precipitation method. This work achieved the synthesis of MSNs with specific surface area (SSA) (~ 500 m 2 /g—1064 m 2 /g), small particle size (~ 90 nm- 133 nm) with narrow pore size distribution ranging between (7.56 nm- 20.11 nm) and reduced agglomeration condition by proposing a unique reactant’s feeding pattern and studying other parameters aiding the controlled synthesis process. The effect of high concentration fluoride ion on cationic cetyltrimethylammonium bromide (CTAB) template was also investigated. A novel CTAB removal method from the highly porous cavities of the silica nanoparticles under mild conditions was proposed. At 50 °C and atmospheric pressure, the foam fractionation technique showed 61% efficiency of CTAB removal while maintaining the porous structure and surface silanol of the particles compared with the traditional calcination method, providing green, economic and sustainable method for surfactant removal in MSNs.

Biomedical imaging has become an essential tool in the field of early cancer diagnosis and treatment. It is of great significance to develop a method that can monitor tumor hypoxia in real time and maintain a good photodynamic therapy (PDT) effect under hypoxic conditions. To achieve this goal, here we designed and synthesized a novel water-soluble porphyrin derivative, PtTSPP. The photophysical properties of PtTSPP were comprehensively characterized by UV–Vis absorption spectroscopy and fluorescence emission. This porphyrin has an extremely large Stokes shift and red emission (λ em = 690 nm), which can effectively reduce the interference of background fluorescence and is used for the fluorescence imaging of HeLa cells. PtTSPP has good water solubility, is not prone to aggregation, and has a high singlet oxygen quantum yield. It also exhibits low dark toxicity and excellent photocytotoxicity. These properties make PtTSPP a promising candidate reagent for biomedical imaging and photodynamic therapy.

Controlling the morphology of Zinc (Zn) deposits is an effective strategy to produce stable Zn-metal batteries. However, the degradation of Zn negative electrodes and changes in their morphology remain poorly understood. Here, we show that the Zn plating process has two distinct stages. The first being the formation of relatively dense, lumpy Zn, while the second involves the formation of porous mossy Zn on its protrusions, which changes into electrochemically inactive dead Zn during stripping. Based on this, we propose a strategy involving a combination of cationic and anionic reagents to revive the dead Zn. The cations create a positively charged inert region on the negative electrode surface for Zn-ion dispersion that inhibits mossy Zn formation, while the anions act as a redox mediator to revive the dead Zn. Consequently, the Zn negative electrode shows a Coulombic efficiency (CE) of 99.7% and stable Zn plating/stripping over 1400 h (10 mA cm −2 and 10 mAh cm −2 ). An Ah-scale pouch cell retains 96.2% capacity after 800 cycles. This work provides key insights into mossy Zn formation and proposes a promising approach for stable Zn-metal batteries.

Photothermal dry reforming of methane, a promising approach to producing syngas, typically uses oxide materials and is mediated by lattice oxygen. However, it is limited by the balance of the oxygen-releasing/replenishing loop. Here, we present a methane activation pathway free of lattice oxygen on a N-Ni/NiCo@C catalyst. Direct involvement of reactive oxygen species (O*/OH*) released from CO 2 promotes effective CH 4 activation and eliminates coke deposition on oxophilic NiCo sites. Control experiments and density functional theory calculations show that forming a C-N-Ni structure is essential for improving catalytic performance. This is achieved by strengtheni ng the electronic interaction between the NiCo nanoparticles and the carbon layer, thereby boosting the elemental steps of CH 4 dehydrogenation and CH* oxidation and preventing metal oxidation. The optimal catalyst exhibits a high light-to-chemical energy efficiency of 52%, maintaining stability during 200 hours of continuous operation at a mild temperature of 540 °C. This work demonstrates that highly efficient and stable photothermal dry reforming of methane can be achieved by bypassing lattice oxygen.

Programmed death-ligand 1 (PD-L1) represents a pivotal target for immune checkpoint blockade therapy. This study developed a novel PD-L1-targeting SPECT probe [ 99m Tc]Tc-G 3 C-2CBM based on dimeric 2-bromo-3-biphenyl (CBM) scaffold design. The probe was designed to enable bivalent interactions through dual CBM domains, exhibiting > 98% radiochemical yield and excellent in vitro stability. Cellular uptake studies revealed significantly higher accumulation in PD-L1-overexpressing A375-hPD-L1 cells compared to A375 cells (14.15 ± 2.11% vs. 5.89 ± 0.55% at 4 h; uptake ratio = 3.20). The probe displayed favorable binding affinity (K D = 36.54 ± 7.28 nM) and inhibitory potency (IC 50 = 69.62 ± 5.15 nM). In vivo SPECT imaging confirmed tumor-specific accumulation, though accompanied by notable hepatic uptake. These results demonstrate that CBM dimerization is a feasible approach for retaining PD-L1 binding and may provide a basis for the future development of multivalent radiotracers.
