Multifunctional graphene-sulfonate interphase enables interface stabilization. • Solvent-repelling sulfonate groups induce Li + solvation and a LiF-rich SEI. • Fixed anions create continuous Li + pathways and accelerates transport kinetics. • The artificial interphase accommodates volume variation and remains intact. • The Si@GS anode achieves 91.6% ICE and 2400 mAh g −1 after 100 cycles at 0.2 A g −1 . Interfacial instability in lithium-ion batteries originates from the ion transport, mechanical deformation, and solvation mediated interfacial reactions. However, integrating these functionalities within a single interfacial layer remains a challenge. Here, a multifunctional artificial interphase is constructed via a coating strategy that integrates fast Li + transport, mechanical buffering, and solvent exclusion. The fixed-anion framework provides continuous Li + coordination sites to facilitate efficient interfacial ion transport, while the conformal artificial interphase accommodates volume fluctuations and preserves structural integrity. More importantly, the artificial interphase intrinsically repels solvent environment and suppressing solvent induced side reactions. This regulation redirects interfacial chemistry toward the formation of a LiF-rich, inorganic-dominated solid-electrolyte interphase (SEI). A silicon-based anode is employed as a model platform to demonstrate the effectiveness of this strategy, delivers a high initial Coulombic efficiency of 91.6% and maintains a reversible capacity of 2400 mAh g −1 after 100 cycles at 0.2 A g −1 . Furthermore, the Si@GS//LiFePO 4 full cell exhibits excellent cycling stability, achieving a capacity retention of 88.4% after 400 cycles at 1C. Mechanistic studies reveal the multiscale regulation of interfacial processes, spanning molecular-scale solvation modulation, nanoscale SEI chemistry reconstruction, particle-level coating integrity, and electrode-level Li + transport kinetics. This work establishes a multifunctional interphase design strategy featuring the ability to repel solvent molecules, offering new insights into the rational design of advanced battery interfaces.

Lanthanide complexes based fluorescent microspheres are widely used in lateral flow immunoassay (LFIA) measurements of small melecules, such as methamphetamine (MET), due to their efficient fluorescence. However, the easily occurred aggregation of lanthanide complexes often leads to concentration quenching effect of fluorescence, which severely deteriorate the biodetection performance of fluorescent microspheres. Here, in order to optimize the distribution of lanthanide complexes, the crosslinked agent dimethacrylate (EGDMA) is introduced in the microspheres polymerization. By adjusting the concentration of EGDMA, the aggregation of lanthanide complexes is reduced, which inhibits fluorescence quenching effect and enhances fluorescence intensity of the fluorescent microspheres. Such fluorescent microspheres thus achieve highly sensitive detection of MET, with showing a detection limit of 0.048 ng mL −1 with excellent stability. This study provides a new idea for the optimal design of lanthanide complexes dispersed fluorescent latex beads, which is expected to promote the development of advanced In Vitro Diagnostics (IVD) technologies to rapid and precise screening of small molecules.

Due to the unique physical characteristics of intervertebral disc degeneration (IVDD) and the pathological microenvironment that it creates, including inflammation and oxidative stress, effective self-repair is impossible. During the process of intervertebral disc degeneration, there is an increase in the infiltration of M1 macrophages and the secretion of proinflammatory cytokines. Here, we designed a novel injectable composite hydrogel scaffold: an oligo [poly (ethylene glycol) fumarate]/sodium methacrylate (OPF/SMA) hydrogel scaffold loaded with dual-drug/sustained-release PLGA microspheres containing IL-4 (IL-4-PLGA) and kartogenin (KGN-PLGA). This scaffold exhibited good mechanical properties and low immunogenicity while also promoting the sustained release of drugs. By virtue of the PLGA microspheres loaded with IL-4 (IL-4-PLGA), the composite hydrogel scaffold induced macrophages to transition from the M1 phenotype into the M2 phenotype during the early induced phase and simultaneously exhibited a continuous anti-inflammatory effect through the PLGA microspheres loaded with kartogenin (KGN-PLGA). Furthermore, we investigated the mechanisms underlying the immunomodulatory and anti-inflammatory effects of the composite hydrogel scaffold. We found that the scaffold promoted cell proliferation and improved cell viability in vitro. While ensuring mechanical strength, this composite hydrogel scaffold regulated the local inflammatory microenvironment and continuously repaired tissue in the nucleus pulposus via the sequential release of drugs in vivo. When degenerative intervertebral discs in a rat model were injected with the scaffold, there was an increase in the proportion of M2 macrophages in the inflammatory environment and higher expression levels of type II collagen and aggrecan; this was accompanied by reduced levels of MMP13 expression, thus exhibiting long-term anti-inflammatory effects. Our research provides a new strategy for promoting intervertebral disc tissue regeneration and a range of other inflammatory diseases.Keywords:drug delivery;hydrogel;intervertebral disc degeneration;immune regulation;kartogenin

Chiral molecules play a very important role in biological systems, and more and more chiral drugs are used in the treatment of diseases. Mandelic acid (MA) is an important chiral starting substance or the key intermediate of some chiral drugs, and the rapid detection of its chiral purity is very important in the synthesis, separation and detection of drugs. In this study, we developed a method for rapid determination of chiral purity of MA by Raman spectroscopy, and measured a series of Raman spectra of different chiral MA. Through the analysis, it is found that the OH stretching vibration peak can be used to identify the components of chiral molecules, and the enantiomeric excess ( ee value) obtained is in good agreement with the real value, and the error is about 5%. The experimental detection speed is fast and the efficiency is high. Our work firstly provides a new idea for the purity detection of chiral molecules by the original Raman spectrum.

There are numerous challenges in the low-cost batch fabrication of high-performance absorbers. A low-cost preparation process for metal-containing acrylic resin ( 3SM-yAN , y = 6, 9 and 12) employs a one-step free radical polymerization of iron (III) chloride, sodium methacrylate, and acrylonitrile. Fe-3SM-yAN was prepared using carbonization. The carbonization of metal-containing acrylic resin was performed at 800 °C in an argon atmosphere for two hours. The broadest effective absorption bandwidth (EAB) of Fe-3SM-9AN absorbing material yielded 8.07 GHz at 2 mm with a minimum reflection loss of − 36.70 dB (11.41 GHz), and the EAB could cover 14.8 GHz (3.2–18 GHz) with a tunable absorber thickness from 1.0 to 5.0 mm. The synergistic effect of impedance matching and strong electromagnetic attenuation was found to yield excellent microwave absorption of Fe-3SM-yAN （y = 6, 9 and 12）. The magnetic porous shell-like Fe-3SM-yAN is potentially highly suitable for batch production of lightweight and efficient microwave-absorbing materials.

Flexible artificial skin sensors have been a hot research topic over the past 20 years due to their remarkable prospects in the fabrication of smart wearable devices. Normally, electronic skin sensors transmit signals via stretchy electrical conductors, and the manufacturing processes are more complicated, involving multiple steps. For the first time, this work reports a facile one-step fabrication of poly(sodium methacrylate-co-vinylimidazole)-Co2+ hydrogels with high mechanical strength, good elasticity, and excellent sensitivity that can be used as ionic skins (I-skins). In addition, mechanical analysis indicates that the designed hydrogels have enhanced strain and tensile strength due to hydrogen bonding and metal–ligand bonding interactions, and these two types of dynamic noncovalent interactions are explored in detail. Simultaneously, the developed hydrogels also display superior conductivity and self-healing qualities with restored sensing properties. Furthermore, the proposed hydrogel with good sensitivity and stable strain range is suitable to fabricate a wearable strain sensor, and this hydrogel sensor was demonstrated to be effective in monitoring human motion, including joint flexion, pulse, vocal cord vibration, and respiration. In addition, a pressure distribution sensor array was developed by this hydrogel and was used to construct the model of plantar pressure distribution in normal subjects and flatfoot patients, offering a strategy for the early detection and clinical diagnosis of numerous foot-related disorders. Hence, this research may offer a promising approach for generating biocompatible hydrogels with integrated mechanical characteristics, and these hydrogels present development potentials in multifunctional ionic skins.

Nanointerfacial decoration of silver nanoparticles (AgNPs) is an ideal protocol to improve the antibacterial efficiency of diverse nanomaterials, including carbon nanotube (CNT), graphene, and many other intensively studied nanoarchitectures, which provides a tremendous possibility for designing advanced antibacterial biomaterials and biomedical devices. However, the direct exposure of AgNPs will lead to potential mammalian cell apoptosis and death, which significantly limits their biological applications. In this study, we demonstrated a green and one-step approach to achieve robust antibacterial and highly biocompatible AgNP–CNT composites. AgNPs were produced via mussel-inspired “one-step” in situ reduction and coating process and were anchored onto the surface of a CNT. Simultaneously, protective polymer layers were formed to shield the AgNPs to improve their biocompatibility. Because of the bactericidal efficiency of AgNPs, the composites showed robust antibacterial efficiency in terms of both inhibition of bacterial cell growth and bacterial killing activity. Moreover, owing to the shielding effects of the polymer coatings, the nanocomposites exhibited much improved compatibility with human umbilical vein endothelial cells compared with bare AgNP–CNTs. Furthermore, the nanocomposites exhibited good stability in psychological solutions. With integrated excellent antibacterial activity, cell compatibility, and long-term stability, it is believed that the synthesized AgNP–CNT composites will be of promising potential in antibacterial applications. Meanwhile, the proposed strategies can also be applied to fabricate many other kinds of AgNP-based composites because of the versatile functionality of catecholic polymers.

Monolithic porous copolymers with 3D structure were prepared via CO 2 -in-water high internal phase emulsions template by graft copolymerization of sodium methacrylate (MAANa) on to methyl cellulose (MC) backbone. The yielded copolymer monoliths are characterized by Fourier transform infrared spectra, scanning electron microscopy (SEM), and mechanical instrument, the swelling degree of MC- g -PMAANa monoliths with different crosslinker in diverse pH were investigated. The adsorption performance of monolith to Cu(II) were conducted to explore its adsorption capacity to heavy metal ions from the wastewater. Then, a strategy of in situ growth of metal-organic frameworks (MOFs) on MC- g -PMAANa that adsorbed with metal ions was proposed first. The X-ray powder diffraction, SEM, and Brunauer-Emmett-Teller (BET) surface area result of MC- g -PMAANa/MOFs composites indicated that the MOFs nanoparticles were grown uniformly on the monolith wall without destroying its original 3D porous structure. Compared with MOFs nanoparticle, MC- g -PMAANa/MOFs composites have advantages of easy operation and handle, which more conform to practical application. Furthermore, the antibacterial activity of MC- g -PMAANa/MOFs was evaluated by disk agar diffusion and optical density methods. In addition, MC- g -PMAANa/Cu-BTC composite was applied to dye adsorption, which has proved the underlying application of such composites in dye removal.

Precise and programmable control of reversible deformations of hydrogels has important implications for bionics. This work reports on programmable three-dimensional (3D) deformations and thermoresponsive actuation of polymer hydrogels in a well-defined manner. Precise infiltration of Fe3+ with periodic patterns is additionally used to cross-link the local polymer network through ionoprinting with a patterned electrode array. The patterned Fe3+ cross-linking generates periodic undulations in cross-link density, stiffness, and thermoresponsiveness. The internal stress induces 3D helical structures with tunable chirality and dimensions. The differential thermoresponsiveness imbues a fourth dimension to the shape deformations. Moreover, sequential ionoprinting generates well-defined in-plane periodic distributions of differential modulus and responsiveness, leading to 3D/4D umbrella-like origami upon temperature triggers.

Selective capture of mono-, multi- or global phosphopeptides is significant for the in-depth study of protein kinase or phosphatase signal transduction pathways. However, this study is largely restricted because of the lack of versatile affinity materials with high enrichment capacity and tunable selectivity. Here, we prepared a smart nanoprobe for the selective enrichment of mono-, multi- or global phosphopeptides by introducing polyamidoamine dendrimer (PAMAM)-grafted poly(methacrylic acid) (PMAA) brushes to modified magnetic composite nanospheres (denoted as Fe3O4@PDA@PMAA@PAMAM). The practicability of the prepared nanospheres for phosphopeptide enrichment was investigated by using model proteins (α-casein and β-casein) and complex biological samples (nonfat milk and human saliva). The extremely abundant amine groups of PAMAM–PMAA brushes and superparamagnetism of the Fe3O4 core endowed the composite nanospheres with high detection sensitivity (1 fmol μL−1), excellent selectivity (1 : 500 molar ratios of β-casein/BSA) and high recyclability (five cycles) towards phosphopeptides. Additionally, based on the tunable bonding ability of the nanospheres towards phosphopeptides with different phosphorylation sites, selective enrichment of mono-, multi- or global phosphopeptides was realized by modulating buffer polarity and acidity, making them ideal new nanoprobes for comprehensive phosphoproteome analysis.

The design of a hydrogel material with cold-adaptation and switchable properties is incredibly significant for developing flexible electronics to accommodate diverse application requirements. Herein, an anti-freezing and biocompatible hydrogel sensor with adjustable performance was constructed by incorporating natural fish antifreeze proteins into a hydrogel system consisting of chemical crosslinking poly(acrylamide/sodium methacrylate) and physical crosslinking polyvinyl alcohol. The biocompatible hydrogels with conductivity and shape-adaptability demonstrated tunable features between extraordinary self-adhesion and robust mechanical strength for adapting personalized application requirements. Meanwhile, breaking through the conventional anti-icing strategy, the ice crystals inhibition ability of antifreeze proteins endowed hydrogels with an anti-freezing performance at low-temperature conditions. Additionally, the hydrogels exhibited fast and extremely sensitive responsiveness to mechanical deformation, together with insignificant asynchronism of input/output signals. As a result, the hydrogel sensors could attach directly to human skin for perceiving various body motions and physiological movements, with the advantages of perfect accuracy and reproducibility. Besides, the sensors were competent for capturing unpredictable animal behavior in real-time. The property-tunable design strategy and fish-inspired anti-icing method fuel an exciting new direction for wearable devices for serving in diverse fields.

Water scarcity and pollution has become one of the most serious problems in the world. Generally, both oils and microorganisms exist in polluted water, hence multi-functional materials for the removal of diverse substances from water are desired. We reported a facile method for preparing cotton fabric possessing hybrid poly(sodium methacrylate) (pNaMAA)/silver nanoparticles (AgNPs) for oil/water separation and water disinfection. A crosslinked pNaMAA layer was generated on the cotton surface by ultraviolet-initiated polymerization. By replacing Na+ in pNaMAA molecules, Ag+ was incorporated into the fabric and then was reduced to AgNPs in situ by photo-thermal reduction. Due to the high underwater oleophobicity and bactericidal effect of the pNaMAA/AgNP hybrid layer, the gravity-driven oil/water separation efficiency of the prepared fabric was higher than 99% and the bacteria killing ratio achieved nearly 100%. Furthermore, AgNPs exhibited relatively good fastness during application. Combining their excellent oil removal and water disinfection effectiveness, these textile-based materials provide a promising future in the field of point-of-use water purification.
