Molybdenum disulfide (MoS 2 ) has emerged as a promising anode material for lithium-ion and sodium-ion batteries, yet its practical application is limited by sluggish ion diffusion and low electrical conductivity. Herein, we propose a glucose-assisted hydrothermal strategy that simultaneously enables 1T/2H phase engineering, carbon intercalation, and hierarchical MoS 2 –carbon coupling—forming a “three-in-one” composite structure. The synthesis is achieved using halloysite-derived carbon nanotubes as templates, leading to a 1T/2H-MoS 2 /carbon composite with expanded interlayer spacing and a porous framework. As an anode material, 1T/2H-MoS 2 /C3 delivers outstanding performance, achieving 926.7 mAh g −1 after 100 cycles at 0.2 A g −1 and 544.6 mAh g −1 after 10,000 cycles at 5 A g −1 in lithium-ion cells. In sodium-ion cells, it maintains 403.4 mAh g −1 after 200 cycles at 0.2 A g −1 and 173.5 mAh g −1 after 10,000 cycles at 5 A g −1 . These remarkable enhancements arise from the synergistic effects of the “three-in-one” design, which collectively optimize electronic conductivity, lower ion diffusion barriers, and ensure structural integrity over long-term cycling.

Multidrug-resistant (MDR) bacterial infections remain a critical public health concern worldwide, with conventional antibacterial strategies presenting limitations such as inconsistent target localization, suboptimal therapeutic efficiency, and progressive antimicrobial resistance development. Nitric oxide (NO), a bioactive molecule, exhibits potent antibacterial effects, resulting in the emergence of NO-based gas therapy as a promising and innovative therapeutic strategy. However, these therapies present the principal challenge of effective NO delivery, owing to its short half-life and limited diffusion capacity. Hence, this study aimed to develop AI‑molybdenum disulfide (L-Arg/IR780@MoS 2 ) nanoflowers (NFs) employing L-arginine (L-Arg) as an endogenous NO precursor and MoS 2 as a dual carrier for L-Arg and IR780 iodide (IR780). Following near-infrared irradiation during photodynamic therapy, generated reactive oxygen species initiated an oxidation cascade for L-Arg-to-NO conversion. The produced NO, in combination with photothermal therapy, modulated the bacterial microenvironment. This significantly altered the expression of key genes in MDR bacteria associated with nucleotide metabolism and biofilm formation, thereby effectively disrupting biofilms and suppressing bacterial growth. Furthermore, the AI-MoS 2 NFs exhibited notable ancillary therapeutic benefits, including anti-inflammatory activity, enhanced re-epithelialization, increased collagen deposition, and angiogenesis modulation, which collectively accelerated wound healing. Altogether, the findings of this study present a synergistic therapeutic strategy designed to address the dual challenges posed by bacterial biofilms and antimicrobial resistance.

The cyclic life, rate performance, specific energy, and electrochemical sensing of electrode materials can be enhanced by tuning their nanostructures and compositions. Herein, the chemical vapor deposition technique was used to make direct deposition of MoS 2 nanosheets and Ni 3 S 2 /MoS 2 nanospheres on hierarchical nickel foam. The evaporated Ni 3 S 2 and MoS 2 achieved different energies, resulting in their different growth of diffraction planes with different peak intensities. The nanosheets and nanospheres were deposited successfully, which could render good surface area ∼50 m 2 g −1 , 128 m 2 g −1 , and pore ∼6.25 nm and 25 nm, respectively. The deposited MoS 2 and Ni 3 S 2 /MoS 2 electrodes provided a commendable capacitance of 1045 Fg −1 and 1828 Fg −1 at 1 Ag −1 , good cyclic life retaining 73% and 89% of their initial capacitance after 10,000 cycles with columbic efficiency of 85% and 98%. Besides, the asymmetric supercapacitor disclosed outstanding capacitance of 943 Fg −1 , specific energy of 297 Whkg −1 , with specific power of 2100 Wkg −1 at 3.5 Ag −1 and cyclic stability retaining 89.14% after 10,000 cycles at 35 Ag −1 . In electrolytic glucose oxidation, the Ni 3 S 2 /MoS 2 electrode also exhibited diffusion process contributions of ∼98–95% to the overall response at 5–30 mVs −1 , with surface process contributions of ∼2–5%.

Achieving precise integration of molecular targeting, controlled drug release, and efficient photothermal conversion remains a critical challenge in the development of synergistic cancer nanotherapies. Here, we presented a programmable dual-aptamer DNA–MoS2 quantum dot (QDs) nanoplatform, constructed via multivariate hydrothermal synthesis and rolling circle amplification (RCA). Systematic optimization identified glutathione as the optimal sulfur source, resulting in the preparation of ultrasmall MoS2-QDs with strong 808 nm absorption, high colloidal stability, and excitation-dependent fluorescence. Covalent conjugation of these QDs to an RCA-derived DNA scaffold enabled high-density assembly of MUC1 and AS1411 aptamers and facilitated efficient doxorubicin (DOX) intercalation within GC-rich duplex regions. The resulting nanoplatforms demonstrated selective uptake by MCF-7 breast cancer cells, negligible internalization in normal fibroblasts, and DNase-responsive drug release. Upon near-infrared irradiation, the dual-aptamer assemblies elicited rapid photothermal heating, elevated intracellular reactive oxygen species (ROS), and mitochondrial dysfunction, generating a potent synergistic chemo-photothermal cytotoxicity. DOX-loaded RA@QDs further inhibited cancer cell migration, highlighting the enhanced therapeutic efficacy. This modular nanoplatform integrates the programmable DNA architecture, precise molecular targeting, enzyme-responsive drug delivery, and efficient photothermal activation, providing a scalable and mechanistically unified strategy for precision cancer nanomedicine.

A major significance persists in the construction of cost-effective electrocatalysts possessing both outstanding activity and robust durability for water and urea electrolysis, which is essential for realizing energy-saving hydrogen evolution. However, it is still challenging to explore bifunctional electrocatalysts under ampere-level current density. Herein, we report the construction of a three-phase heterojunction electrocatalyst with bifunctional activity toward both hydrogen evolution reaction (HER) and urea oxidation reaction (UOR), achieved through the deliberate tuning of morphological features and electronic configurations. Through local bonding environment engineering at the heterointerface, the unique heterostructure effectively accelerates electron transfer and interfacial interactions, leading to significantly improved reaction kinetics and intrinsic electrocatalytic activity. Density functional theory (DFT) calculations reveal that the multi-heterostructure promotes electron migration and interfacial coupling via the concerted regulation of the electronic configuration, d-band center position, and density of states (DOS). These modifications collectively lower the chemisorption free energies of reaction intermediates, thereby accelerating the dissociation of both water and urea molecules. As a result, the heterojunction electrocatalyst exhibits ultralow potentials of −0.198 and 1.41 V to reach 1000 mA cm −2 for HER and UOR, respectively. Notably, when employed as a urea-assisted electrolyzer, the system achieves a cell voltage of 1.58 V at 500 mA cm −2 , which is 200 mV less than that required for conventional water electrolysis. Furthermore, the UOR-HER electrolyzer exhibits robust operational stability, sustaining 500 mA cm −2 for 100 h without significant degradation. Collectively, this study establishes a novel and practically viable route toward low-energy-consumption hydrogen production.

Molybdenum disulfide (MoS 2 ) serves as an outstanding solid lubricant applied in harsh service conditions. However, enhancing its lubricating, antioxidative and anti-wear capabilities over a broader temperature range stills a formidable challenge, owing to its susceptibility to oxidation at high-temperature. In this work, we achieved superior wide-temperature lubrication from room temperature (RT) to 800 ℃ via the design of core-shell structure, with the introduction of Bi 2 O 3 nanoparticles and encapsulation of SiO 2 shell, and phosphate as binder. At RT and 200 ℃, stable low friction was realized through the synergistic interlayer sliding of MoS 2 and in-situ formed Bi 2 S 3 with low shear strength. At 400 ℃, the protective SiO 2 shell inhibited the oxidation of the core lubricating phase, thus enabling MoS 2 and Bi 2 S 3 to retain their lubricating functionality. When the temperature exceeded 600 ℃, the remarkable enhancement in lubricating property (with a coefficient of friction of 0.13–0.16) was attributed to the synergy of phosphate molten-phase lubrication and low-shear lubricating phases (Bi 2 S 3 and Bi 2 MoO 6 ). An amorphous phosphate molten layer formed at high temperatures and constructed a readily shearable lubricating interface. Low-shear lamellar-chain structure Bi 2 S 3 , weak interlayer van der Waals forces reduced the sliding resistance. The distorted MoO 6 octahedral structure of Bi 2 MoO 6 induced an enlarged interlayer distance and weakened interionic coupling, which enhanced shear capability and excellent high-temperature lubrication performance. This work provides some reference for improving wide-temperature-range lubricating capabilities of solid lubricating materials.

s Quantitative detection of Golgi protein 73 (GP73), a promising biomarker for hepatocellular carcinoma (HCC), is crucial for early diagnosis. In this study, we developed a fluorescence aptasensor for sensitive and specific detection of GP73 based on fluorescence resonance energy transfer (FRET) between GP73 aptamer-functionalized nitrogen/sulfur co-doped graphene quantum dots (N, S-GQDs-GP73 Apt ) as the fluorescence donor and molybdenum disulfide@reduced graphene oxide (MoS 2 @RGO) as the fluorescence acceptor. In the absence of GP73, the fluorescence of N, S-GQDs-GP73 Apt was effectively quenched by MoS 2 @RGO. Upon introduction of GP73, specific binding between GP73 and its aptamer triggered dissociation of the donor-acceptor complex, disrupting FRET and restoring fluorescence. Under optimized conditions, the normalized fluorescence intensity showed a good linear relationship with GP73 concentration ranging from 0.0001 to 100.0 μg/mL, with a low detection limit of 0.019 ng/mL. The aptasensor's performance was further validated using human serum samples with relative error ranging of 0.76%–3.85% and no statistically significant difference via t -test compared with ELISA results, demonstrating its potential as a reliable and cost-effective platform for early HCC diagnosis.

Hydrogen evolution reaction (HER) in alkaline media demands cost-effective and highly active electrocatalysts to replace noble metals. Herein, we report a ternary MoS₂/Ni₃S₂/Ni(OH)₂ nanoflower composite supported on nickel foam (NF) via a facile one-step electrodeposition strategy. This method enables precise control of MoS₂ morphology while mitigating aggregation-induced active site blockage. The synergistic interplay among MoS₂ (exposing edge sites), conductive Ni₃S₂, and Ni(OH)₂ (modulating electronic structure) significantly enhances HER kinetics. Notably, the optimal catalyst (5-min deposition) achieves ultralow overpotentials of 48 mV at 10 mA cm⁻² and 175 mV at 100 mA cm⁻² in 1.0 M KOH, surpassing most reported Ni- or Mo-based catalysts. Furthermore, it exhibits exceptional stability with negligible activity loss after 5000 cycles and 72-hour continuous operation. XPS analysis reveals that a high Mo⁴⁺/Mo⁶⁺ ratio facilitates electron delocalization, accelerating hydrogen intermediate desorption. This work establishes a new paradigm in HER catalyst design through interface-engineered ternary systems. By unifying electronic synergy theory with the SPRE synthesis method, we overcome the activity-stability trade-off plaguing binary catalysts. The demonstrated 500-hour stability at industrial current densities (100 mA cm⁻²) positions this approach as a transformative solution for scalable green hydrogen production. Graphical

The work presented here describes a highly sensitive and simple electrochemical sensor for the detection of Sudan I dye based on a nanocomposite made of MoS2 heterogeneous nanosheets (1T@2H-MoS2) and carboxylated carbon nanotubes (cMWCNTs) (1T@2H-MoS2/cMWCNTs). XPS results indicate that the content of 1T phase MoS2 was estimated to be 72% in 1T@2H-MoS2. Electron microscopy results show that the tubular cMWCNTs are uniformly interwoven in MoS2 nanosheets to form a three-dimensional network structure. Due to the synergistic electrocatalytic ability and high electroactive surface area, the 1T@2H-MoS2/cMWCNTs modified electrode demonstrated excellent analytical performance for Sudan I, including simple operation, good stability and a wide linear range from 5.00 × 10−9 to 2.00 × 10−6 mol L−1 and 2.00 × 10−6 to 1.00 × 10−4 mol L−1 with an ultra-low detection limit of 1.56 × 10−9 mol L−1. The recoveries of Sudan I from spiked real samples (chilli powder and ketchup) were in the range of 95.60% to 106.10% with low RSD (<5%), indicating that the 1T@2H-MoS2/cMWCNTs modified electrode is a promising tool for the analysis of illegal Sudan I in food samples.

With large surface-responsive and excitation-dependent fluorescence, two-dimensional fluorescent quantum dots (QDs) have been receiving tremendous attention to develop their facile synthetic approaches and/or expand their promising applications. Here, a two-step strategy is demonstrated for high-yield production of MoS 2 QDs from MoS 2 powder through first sonication-driven exfoliation and subsequent hydrothermal splitting with the assistance of bovine serum albumin (BSA). Experimentally, ∼100 nm-sized MoS 2 nanosheets are ultrasonically exfoliated from MoS 2 powder in a BSA solution, and further hydrothermally split into ∼ 8.2 nm-sized QDs (NQDs) at 200 °C. In addition to their excellent stability/dispersibility in aqueous solution, the resultant MoS 2 NQDs also exhibit much brighter blue fluorescence than those synthesized by other methods. The strong fluorescence is significantly quenched by p-nitrophenol for constructing a sensitive sensor with high selectivity, which is attributed to dual quenching effects from inner filter effect (IFE) and fluorescence resonance energy transfer (FRET). Interestingly, with the increment of pH from 5 to 10, the ratio of IFE in fluorescence quenching gradually decreases accompanied by an increment of FRET ratio, resulting in the high sensitivity and responsivity for detecting p-nitrophenol at a wide range of pH. Clearly, the MoS 2 NQD-based sensing approach demonstrates a promising potential for selective detection and fast analysis of pollutants in environment monitoring and security screening.

Developing non-noble and high activity electrocatalysts is the key to electrocatalytic water-splitting. Recently, MoS 2 shows vast perspectives due to its excellent catalytic performance and chemical stability in acid condition. Herein, to expand its application in different environment, a unique ternary composite MCNTs@CoS x @MoS 2 comprising three-dimensional lamellar heterostructure supported by multiwalled carbon nanotubes was successfully prepared by a two-step solvothermal strategy and used in electrocatalytic field. As a bifunctional electrocatalyst, heterostructure MCNTs@CoS x @MoS 2 could catalyst HER with a small overpotential of 196 mV and low Tafel slope of 65 mV dec −1 in acid condition and exhibit outstanding OER performance with a low overpotential of 285 mV and small Tafel slope of 76 mV dec −1 in alkaline solution. Meanwhile, it displayed excellent durability both in an acid and alkaline solution. The remarkable electrochemical performance of MCNTs@CoS x @MoS 2 can be attributed to novel construction advantages and synergy of MCNTs, small CoS x nanoparticles and lamellar MoS 2 . This work can be extended to the design and preparation of a series of composite materials with the advantage of structural diversity.

Pesticides, extensively used in agriculture production, have received enormous attention because of their potential threats to the environment and human health. Hence, in this study, a kind of highly sensitive and stable hybrid surface-enhanced Raman scattering (SERS)-active substrates constructed with flower-like two-dimensional molybdenum sulfide and Ag (MoS2@Ag) has been developed, and then the above substrate was sequentially utilized in the recyclable detection of pesticide residues on several kinds of fruits and vegetables. In the first place, the excellent photocatalytic performance of the MoS2@Ag hybrid substrate was demonstrated, which was attributed to the inhibition of electron–hole combination after the formation of Schottky barrier between the Ag NPs and MoS2 matrix. Thereafter, two calibration curves with ultra-low limits of detection (LOD) as 6.4 × 10–7 and 9.8 × 10–7 mg/mL were established for the standard solutions of thiram (tetramethylthiuram disulfide, TMTD) and methyl parathion (MP), and then the recyclable assay of their single and mixed residues on eggplant, Chinese cabbage, grape, and strawberry was successfully realized. It is interesting to note that the detection recoveries from 95.5 to 63.1% for TMTD and 92.3 to 62.6% for MP are greatly dependent on the size and surface roughness of these foods. In a word, the MoS2@Ag composite matrix shows attractive SERS and photocatalysis performance, and it is expected to have the potential application on food safety monitoring.
