For wearable thermal management, phase change materials (PCMs) with solar-thermal conversion capacity are highly desired. However, traditional solid–liquid PCMs suffer challenges such as inherent solid stiffness, liquid leakage, and limited motion sensing capability. Herein, the flexible POE elastomer functions as a continuous supporting phase encasing n-octadecane in these innovative Ti3C2Tx MXene/polyolefin elastomer (POE)-based phase change foaming films (FPPMs), which have high flexibility and form stability, superior solar-thermal conversion efficiency, and sensitive motion detection. The supercritical carbon dioxide (scCO2) foaming technique was employed to enhance the flexibility and thermal insulation performance of the synthesized flexible phase change films. The FPPMs demonstrated a relatively high energy storage density (147.6 J/g), excellent form stability, superior thermal management performance, and remarkable flexibility (tensile stress up to 1000 kPa). Additionally, the incorporation of single-layer Ti3C2Tx MXenes significantly enhanced the solar-thermal conversion efficiency (up to 86.94%) and improved the motion detection sensitivity of the PCM films. The FPPMs can be employed as a strain sensor to detect various human motions, including facial expression, wrist bend, elbow bend, and finger bend.

A gold nanoparticle (AuNP)-Ti 3 C 2 T x -MXene-poly(diallyldimethylammonium chloride) (PDDA)-reduced graphene oxide (rGO) composite was prepared for electrochemical detection of hexavalent chromium (Cr (VI)). Firstly, Ti 3 C 2 T x -MXene was prepared by HF etching of aluminum titanium-carbide (Ti 3 AlC 2 ), and AuNP-MXene composite was prepared by self-reduction method. Then, the PDDA functionalized rGO (PDDA-rGO) was prepared by hydrothermal reduction method. Finally, the AuNP-Ti 3 C 2 T x was assembled on PDDA-rGO by the electrostatic interaction, and an AuNP-Ti 3 C 2 T x -PDDA-rGO composite was obtained. The composition and morphology were characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and Raman spectroscopy. The electrochemical behavior of Cr (VI) on the composite modified electrode was studied carefully. The results showed that PDDA-rGO can be used as a good carrier to firmly load AuNP-Ti 3 C 2 T x by electrostatic interaction. The simultaneous introduction of AuNP and Ti 3 C 2 T x enhanced the electrochemical activity of the composite. Under the synergistic action of various components, the composite showed strong catalytic activity for the electrochemical reduction of Cr(VI). The linear range of amperometric detection of Cr(VI) was 2.0 × 10 −8 –1.1 × 10 −5 mol/L and 1.1 × 10 −5 –3.9 × 10 −4 mol/L. respectively. The detection limit is 1.0 × 10 −8 mol/L (S/N = 3). The composite electrode had the characteristics of low detection limit, high sensitivity and wide linear range, and can be used for quantitative determination of Cr (VI) in water samples.

A dual-mode (colorimetric/electrochemical) aptasensor was developed for ZEN detection. • Au@Ti 3 C 2 T x MXene@MoSe 2 was synthesized to enhance electrode conductivity and surface area. • RCA was integrated to generate G-quadruplexes for both electrochemical and colorimetric readouts. • Electrochemical mode achieved 1.23 fg/mL LOD; colorimetric mode enabled convenient visual screening. • The sensor exhibited excellent selectivity, stability, and recoveries (89.6–106.2%) in real samples. Zearalenone (ZEN), a nonsteroidal mycotoxin produced by Fusarium fungi, widely contaminates cereals and their derived products, posing a serious threat to human health. In this study, a highly sensitive dual-mode (colorimetric and electrochemical) aptasensor for ZEN was constructed. The sensor employs rolling circle amplification (RCA) to efficiently generate long single-stranded DNA rich in G-quadruplex sequences, combined with an electrode modified with an Au@Ti 3 C 2 T x MXene@MoSe 2 nanocomposite, thereby achieving synergistic signal amplification and dual readout. In the electrochemical mode, the RCA product is anchored through hybridization between the primer and the capture probe on the electrode surface, where it adsorbs abundant methylene blue to produce a square wave voltammetry (SWV) response. In the colorimetric mode, the G-quadruplex structures self-assemble with hemin to form peroxidase-mimicking DNAzymes, which catalyze the TMB chromogenic reaction to generate a visual signal. Experimental results showed that the electrochemical mode achieved a detection limit as low as 1.23 fg/mL (detection range: 10 −3 -10 4 pg/mL), while the colorimetric mode exhibited a detection limit of 64.89 fg/mL (detection range: 1 pM-10 μM). The aptasensor demonstrated excellent selectivity, good stability, and satisfactory reproducibility for ZEN, with spiked recoveries ranging from 89.6% to 106.2% in real corn flour and beer samples. This dual-mode sensing platform effectively eliminates single-mode interferences through signal cross-validation, providing a reliable technical means for the accurate and rapid detection of trace ZEN in food safety.

In pursuing efficient photocatalytic systems, nature-inspired photocatalysis has emerged as a promising strategy to optimize charge transfer and surface reactions. Inspired by the structure and function of plant leaves, a leaf-like hierarchical heterostructure is constructed. ZnIn 2 S 4 nanosheet arrays are anchored on the integrated Ag nanowires network with Ti 3 C 2 T x MXene support, during which process sulfur vacancies (V S ) are formed due to the anti-strong metal-support interaction. The ZnIn 2 S 4 nanosheet arrays supported by Ti 3 C 2 T x serve as mesophyll to absorb photons and convert solar-to-chemicals, the Ag nanowires embedded in the interface of ZnIn 2 S 4 and Ti 3 C 2 T x function as veins to shuttle the charge carriers for the surface redox reactions, and the V S on ZnIn 2 S 4 resemble stomata to facilitate the adsorption of reactants. Furthermore, the formed V S are able to reduce the thermodynamic barriers in photocatalytic reactions. The synergistic effect of these functional components enables hydrogenation of several nitroaromatic compounds, and exhibits a photocatalytic H 2 evolution rate of 1119.4 µmol g⁻¹ h⁻¹ under visible-light irradiation, which is ≈7.9 times as high as that of pure ZnIn 2 S 4 . This study highlights the pivotal role of functional design inspired by nature in advancing solar-to-chemical conversion and paves the way for the development of next-generation photocatalysts in green chemistry and H 2 energy applications.

Ti3C2Tx MXene has a high specific surface area and high conductivity, and can be used in the field of humidity sensing. By controlling the surface termination and microstructure of the material, it is expected to improve the humidity sensing performance of Ti3C2Tx MXene. In this paper, we report a method of electrolytic intercalation treatment of Ti3C2Tx MXene in NaOH solution. Theoretical and experimental results show that this method can remove the original F terminations from the surface of Ti3C2Tx MXene and form a large number of OH and O terminations. The partial oxidation of the surface and the replacement of terminations and the insertion of Na+ lead to the change of the Ti3C2Tx MXene layer morphology from flat to curly and significantly improve the hydrophilicity and resistance. The curly flake structure constructs a fast channel for the entry and exit of water molecules which improves the hydration/dehydration efficiency of the material; the enhanced hydrophilicity of the material sharply reduces the resistance of the material after moisture absorption, which significantly improves the responsiveness of Ti3C2Tx MXene to humidity. The curly flake Ti3C2Tx MXene humidity sensor has an ultra-high sensitivity of S = 1.2 × 105 (two orders of magnitude higher than that of the reported humidity sensor based on MXene), with a fast response rate (2 s), good repeatability and stability (4 weeks), and it can be used for the analysis of human respiration rate, and also for non-contact sensing detection of the human body and environmental humidity detection.

Exploring an efficient and stable adsorbent material for purification of toxic heavy metal ions wastewater is of great significance. However, as a typical heavy metal ions adsorbent, titanate can still improve in material synthesis, adsorption efficiency and the recyclability . Herein, a novel titanate-based adsorbent which composing of Ti 3 C 2 T x MXene-derived hydroxy-rich titanate and cellulose was fabricated for efficient removal of toxic heavy metal ions. Owing to the similar stratified structure, the conversion from Ti 3 C 2 T x MXene to titanate is energy-saving and easy to achieve. In addition, the inherited hydroxy-rich property is beneficial to improve the adsorption efficiency of the derived titanate. Furthermore, the introduction of cellulose as a structural regulator to fabricate the titanate/cellulose membrane could greatly alleviate the problem of difficult recycling of powder adsorbent. Thus, the constructed Ti 3 C 2 T x -derived hydroxy-rich titanate/cellulose membrane adsorbent (M-NTO/CM) exhibits high Cu 2+ adsorption capacity of 2.63 mmol g −1 and can reach the adsorption equilibrium in only 5 min. Better yet, there has also been a significant improvement in acid resistance and recyclability of the M-NTO/CM relative to traditional titanate. In short, M-NTO/CM derived from Ti 3 C 2 T x MXene can be used as an advanced membrane for convenient and efficient purification of heavy metal ions from the wastewater.

Wearable heaters have attracted growing attention for maintaining a relatively constant temperature of the human body in cold environments with near zero energy consumption. Herein, we developed a multifunctional laminated fabric with fascinating electro/solar-thermal conversion, thermal energy storage and thermal insulation properties. With cotton fabric as the substrate, MXene/polydimethylsiloxane (PDMS) conductive network was decorated on the upper layer, and carbon nanotube (CNT)/cellulose nanofiber (CNF)/paraffin (PA) aerogel phase change composites were assembled on the bottom layer. Attributed to the strong conductivity and light absorption of MXene and the light/thermal response of CNT and PA components, this wearable laminated fabric broke the limitation of intermittent solar photothermal heating, and integrated multiple heating modes to precisely heat the human body. Meanwhile, the low thermal conductivity of aerogel retarded heat loss. The laminated fabric can help people better adapt to a variety of complex and changeable environments such as cold winter, rainy days and nights. This study provides a promising and energy-efficient avenue for the development of all-day personal thermal management fabrics.

Synthesis of fluorescent carbide-derived carbons (CDCs) remains a big challenge for material scientists. Herein, we report an unprecedented method for the synthesis of amphiphilic carbide-derived graphene quantum dots (GQDs) from layered Ti 3 C 2 T x MXene using solvothermal treatment of Ti 3 C 2 T x MXene in dimethylformamide (DMF). Our findings indicate that DMF can simultaneously act as reaction media and nitrogen-doping agent for the formation of highly fluorescent carbide-derived GQDs. The resulted GQDs with uniform size distribution exhibit excellent dispersibility in both hydrophilic solvents (e.g., water, DMF, and ethanol) and in hydrophobic solvents (e.g., chloroform and toluene). With their superior properties of bright and tunable photoluminescence , low cytotoxicity, good photostability and chemical inertness , the carbide-derived GQDs are promising for applications in fluorescent ink, light-emitting composites and cellular imaging as demonstrated in this paper. This work opens a new route towards the large-scale synthesis of high-quality GQDs, paving the way for their versatile applications.

Human immunodeficiency virus (HIV) is still a significant global health concern. Hence, developing a rapid and sensitive method for the detection of HIV is important in early detection. In this paper, we focus on the preparation of a sensitive electrochemical luminescence (ECL) biosensor that uses Ti 3 C 2 T x modified ZIF-8 as an ECL emitter to detect HIV-1 protein. This ECL biosensor used 0.05 M K 2 S 2 O 8 as the co-reactant and conductive carbon black combined with magnetic nanoparticles as the quenching agent. Under the optimized experimental conditions, the relationship was linear in the range from 1 fM to 1 nM (R 2 = 0.993) and the detection limit was 0.3 fM (S/N = 3). Finally, we used the constructed Ti 3 C 2 T x /ZIF-8 nanocomposites to detect HIV-1 in real serum samples and obtained great recoveries. The results demonstrated that this biosensor, which not only exhibited improved electrical conductivity but also demonstrated an excellent ECL response, could be a promising candidate for HIV-1 detection.

A promising nanocarrier of the complementary DNA (cDNA) toward miRNA-155 was synthesized on the basis of the nanohybrid type of Ti 3 C 2 T x MXene nanosheets decorated using iron phthalocyanine quantum dots (FePc QDs) (denoted as Ti 3 C 2 T x @FePcQDs) to construct a novel ultrasensitive impedimetric aptasensing system for microRNA-155 (miRNA-155). Owing to π–π* stacking interaction between Ti 3 C 2 T x nanosheets and FePc QDs, the homogeneous nanostructure of the Ti 3 C 2 T x @FePcQD nanohybrid that comprises mixed-valence states (Ti 2+ /Ti 3+ and Fe 2+ /Fe 3+ ), multicomponent (Ti-O and Ti-C), and various N-related groups was achieved. The constructed Ti 3 C 2 T x @FePcQDs-based aptasensor displayed an ultrahigh sensitivity for detecting miRNA-155 with a low detection limit of 4.3 aM (S/N = 3) within the miRNA-155 concentration ranging from 0.01 fM to 10 pM. Compared with the individual component-based aptasensors and other reported miRNA-155 aptasensors, the proposed impedimetric aptasensing system exhibited substantial merits of a feasible preparation process, non-use of labels or electrochemical indicators, fast response time, and comprehensive sensing performances for detecting miRNA-155. This strategy for determining miRNAs can extensively be applied as the platform for anchoring other kinds of aptamers in detecting diverse targets, thus indicating its great potential application for the early diagnosis of cancer biomarkers.

Electrochemical water splitting is a potential method for sustainable hydrogen production. Achieving efficient and durable bifunctional electrocatalysts for alkaline water splitting remains challenging due to sluggish OER/HER kinetics and a reliance on noble metals. Here, we introduce MX-CoFe/EMN, a binder-free hybrid electrocatalyst fabricated by sequential electrodeposition of Ti 3 C 2 T x MXene integrated CoFe layered double hydroxide (LDH) nanosheets onto nickel foam. Combining CoFe LDH with MXene, which serves as both conductive scaffold and active component, yields beneficial interfacial electronic interactions, enhanced charge transfer, and a high density of active sites. In 1.0 M KOH, MX-CoFe/EMN shows low overpotentials of 260 mV (OER) and 279 mV (HER) at ±100 mA cm −2 , small Tafel slopes 39 mV dec −1 (OER), 68 mV dec −1 (HER), and excellent durability of over 80 h at ±500 mA cm −2 . These findings demonstrate a scalable electrodepositin-based approach for developing highly active and durable non-noble-metal electrocatalysts for sustainable hydrogen generation.

Nanozymes were emerged as the next generation of enzyme-mimics which exhibit great applications in various fields, but there is rarely report in the electrochemical detection of heavy metal ions . In this work, Ti 3 C 2 T x MXene nanoribbons@gold (Ti 3 C 2 T x MNR@Au) nanohybrid was prepared firstly via a simple self-reduction process and its nanozyme activity was studied. The results showed the peroxidase-like activity of bare Ti 3 C 2 T x MNR@Au is extremely weak, while in the presence of Hg 2+ , the related nanozyme activity is stimulated and improved remarkably, which can easily catalyze oxidation of several colorless substrates (e.g., o-phenylenediamine) to form colored products. Interestingly, the product of o-phenylenediamine exhibits a strong reduction current which is considerably sensitive to the Hg 2+ concentration. Based on this phenomenon, an innovative and highly sensitive homogeneous voltammetric (HVC) sensing strategy was then proposed to detect Hg 2+ via transforming the colorimetric method into electrochemistry since it can exhibit several unique advantages (e.g., rapid responsiveness, high sensitivity and quantificational). Compared to the conventional electrochemical sensing methods for Hg 2+ , the designed HVC strategy can avoid the modification processes of electrode coupled with enhanced sensing performances. Therefore, we expect the as-proposed nanozyme-based HVC sensing strategy provides a new development direction for detecting Hg 2+ and other heavy metals.
