Atmospheric water harvesting (AWH) technology has attracted significant attention as an effective strategy to tackle the global shortage of freshwater resources. Work has focused on the use of hydrogel-based composite adsorbents in water harvesting and water conservation. The approaches adopted to make use of hygroscopic inorganic salts which subject to a “salting out” effect. In this study, we report the first use of modified UIO-66-NH 2 as a functional steric cross-linker and Sa-son seed gum was used as polymeric substrate to construct super hygroscopic hydrogels by free radical copolymerization. The maximum water uptake on SMAGs (572 cm 3 ·g −1 ) outperforms pure UIO-66-NH 2 (317 cm 3 ·g −1 ). Simultaneously, our first attempt to use it for anti-evaporation applications in an arid environment (Lanzhou, China) simulating sandy areas. The evaporation rate of the anti-evaporation material treated with 0.20 % super moisture-absorbent gels (SMAGs) decreased by 6.1 % over 64 h period under natural condition in Lanzhou, China. The prepared material can not only absorb liquid water but also water vapor, which can provide a new way for water collection and conservation technology. The design strategy of this material has wide applications ranging from atmospheric water harvesting materials to anti-evaporation technology.

Sodium-ion batteries (SIBs) are promising for large-scale energy storage due to their high cost-effectiveness and safety. Alloy anodes exhibit significantly higher specific capacities compared to those of carbonaceous anode materials, holding great promise for enhancing the energy density of SIBs. However, their practical application is severely hindered by substantial volume expansion, sluggish reaction kinetics, and continuous fracture reformation of the solid-electrolyte interphase (SEI). Here, a multifunctional composite binder system was designed for the Sn anode, which was composed of poly(ethylene oxide) (PEO), sodium alginate (SA), and sodium bis(trifluoromethylsulfonyl)imide (NaTFSI). The PEO-SA-NaTFSI (PSN) binder integrates ternary synergistic functions: robust adhesion between the active material and current collector, enhanced Na+ transport kinetics, and formation of a stable NaF-rich SEI. Therefore, the Sn-PSN anode achieves an outstanding sodium storage performance with a high capacity of 583.4 mA h g–1 at a current density of 10 A g–1 and 77% capacity retention after 1500 cycles. In addition, the Sn-PSN||Na3V2(PO4)3 full battery can maintain 81% capacity after 200 cycles with an electrode energy density of 169.0 W h kg–1. This work provides a multifunctional binder design strategy with broad application prospects for high-performance anodes of SIBs.

In this work, a simple, sensitive and specific assay for DNA was proposed by combining inductively coupled plasma mass spectrometry (ICP-MS) detection with gold nanoparticle (AuNPs) amplification and isothermal circular strand-displacement polymerization reaction (ICSDPR). First, AuNPs were decorated with hairpin-structured DNA (HP-DNA) through Au–S bond to form the AuNPs probe. The ICSDPR was conducted on AuNPs probe in a homogeneous phase to realize the dual amplification and simplify the analytical process at the same time. By using a biotin modified primer, AuNPs were connected with biotins after the ICSDPR, then captured by the streptavidin modified magnetic beads (SA-MBs), and finally detected by ICP-MS. Many key factors including probe volume, hybridization time, polymerase amount, primer concentration, enzyme reaction time, SA-MBs capture time and desorption time were optimized. Under the optimized condition, the proposed method could detect target DNA as low as 45 zmol (8.9 fM in 5 μL) in a relative short time (about 4.5 h) with good specificity, and the linear range of this method is 0.1–10000 pM, the relative standard deviations are in the range of 3.6–6.4%. The proposed method was applied for determination of target DNA in human serum samples, the recovery for the spiked human serum samples is in the range of 84–120%. It demonstrates a good application potential of the developed method for biological studies and clinical diagnosis of human pathogenic diseases.

Sodium alginate (SA) has been widely used in various fields of daily life. However, the lack of antibacterial properties of SA limits its further application. In this work, we successfully developed the antimicrobial SA derivative through the covalent coupling between organosilane quaternary ammonium salt DC-5700 (TSA) and SA using a one-pot reaction. The corresponding structures, molecular weights, morphologies, thermal properties, and viscosity of the SA-TSA samples were comprehensively characterized by FTIR, GPC, SEM, TGA, and rotational rheometer. The best antibacterial efficiency against Staphylococcus aureus and Escherichia coli can reach up to 99.6% and 99.3%, respectively. Specifically, great biocompatibility (> 80%) was observed when the concentration of best antibacterial SA-TSA3 was < 0.50 g/mL. Moreover, the antibacterial potential utility of antibacterial SA-TSA3 was demonstrated by the fabrication of SA beads. Finally, this antibacterial material of SA-TSA3 was expected to show great potential application in biomedical or textile fields. Graphical abstract

With the rapid development of petroleum resources and the chemical industry, the release of oily wastewater has increased dramatically and environmental pollution has become increasingly serious. In this study, an inexpensive, simple, and environmentally friendly technique was established to synthesize a multifunctional melamine sponge (MS) with both superhydrophobic and photocatalytic properties through polydopamine (PDA) functionalization, followed by the immobilization of CNZ (C3N4@ZnO) nanoparticles and the grafting of stearic acid (SA). The prepared SA@CNZ/PMS sponge exhibited outstanding superhydrophobicity with a water contact angle (WCA) of 150.5°. The sponge possesses superior hydrophobic–oleophilic selectivity, which can effectively separate various oil/water mixtures as well as oil-in-water emulsions. Meanwhile, the sponge exhibits high oil sorption capacity (11.55–52.76 times its own weight) and oil–water separation efficiency (99.3% after 10 cycles). In addition, superhydrophobic SA@CNZ/PMS is resistant to chemical corrosion and demonstrates good mechanical stability. Moreover, SA@CNZ/PMS exhibits a rapid removal efficiency for organic dyes (96.4% for methylene blue) through synergistic adsorption and visible light photocatalysis. This research provides new insights into the design of multifunctional materials for treating oily and dye-containing wastewater.

This study presents a reusable adsorbent material for industrial wastewater treatment. Double-network interpenetrating gel beads were prepared via condensation reaction and hydrogen bonding between sodium alginate and collagen, combined with PVA and ion crosslinking. The addition of collagen enhanced the equilibrium swelling ratio, strengthened the double-network structure, and increased adsorption sites. Optimal adsorption of tannic acid occurred at a collagen/PVA mass ratio of 1:2, achieving a maximum capacity of 261.53 mg/g and a removal rate of 78.46%. Influenced by multiple factors, the adsorption process followed pseudo-second-order kinetics, indicating chemisorption dominance. The beads maintained good adsorption capacity and structural stability over four adsorption–desorption cycles, demonstrating excellent reusability.

MicroRNAs (miRNAs) are becoming biomarkers for the clinical diagnosis of many diseases. However, their intrinsic properties such as low enrichment and short sequence restrict their applications. Here, we designed an ultrasensitive dual signal amplification electrochemical biosensor based on sodium alginate-polypyrrole/Au nanoparticles (SA-PPy/AuNPs) nanocomposite for the detection of miRNAs. Firstly, a planar intercalated copper(II) complex was synthesized to be the signal molecule. Then, catalytic hairpin assembly (CHA) reaction and catalytic reaction between ferric ion and copper ion were combined as a dual signal amplification to improve the sensitivity of the biosensor. In the presence of target miRNAs, multiple double helix structure formed for the CHA reaction was triggered, which immobilized more copper(II) complex on the surface of the working electrode and a strong signal was obtained in the square wave voltammetry (SWV) test. Also, the signal can be re-amplified again in the presence of ferric ion in the electrolyte. Under the optimal conditions, based on these strategies, a sensitive electrochemical biosensor was constructed for the detection of miRNAs in the range of 1 fM to 1 nM and the limit of detection was as low as 0.34 fM. Furthermore, the developed biosensor with excellent selectivity and reproducibility tested on human serum samples shows broad application prospects in the early stage of tumor diagnosis.

Polyzwitterionic gels with both positively and negatively charged groups have attracted attention because of their excellent biocompatibility and high water absorption. However, insufficient mechanical properties due to fragile cross-linked networks and low stability due to aqueous solvents are still prominent. In this study, a deep eutectic solvent (DES) was introduced into the sulfobetaine zwitterionic monomer DMAPS([2-(methacryloyloxy)ethyl]dimethyl-(3-sulphonatopropyl)ammonium hydroxide) system. Based on the complexation strategy of sodium alginate (SA) polysaccharide, a polyzwitterionic network skeleton was constructed to prepare a composite eutectogel with high strength, environmental resistance, and high conductivity. The presence of DES enables polyzwitterionic gels to obtain excellent environmental stability at high and low temperatures. Notably, the introduction of SA significantly enhanced the tensile strength, Young’s modulus, and toughness of the eutectogel without affecting the high transparency. This is attributed to the network of hydrogen bonding and electrostatic interactions within the matrix–filler constructed by the hydroxyl-rich and charged groups of SA in the presence of calcium ion complexation. At the same time, the polyzwitterionic network skeleton provides abundant binding sites for ion migration, which endows the eutectogels with excellent ionic conductivity (0.13–0.48 S·m–1). Thanks to its internal porous structure, the composite eutectogel can provide a stable piezoionic output and be used for pressure response and powering LED lights. In addition, supercapacitors and strain sensors assembled on the basis of composite eutectogels proved their potential for applications in areas such as energy storage and human motion monitoring. In conclusion, this study provides important guidance for the construction of biomass ionic network skeletons and the development of high-performance ion-conducting materials.

Stimuli-responsive separation materials with reversible wettability transition have been attracting increasing attention because they have excellent oil/water separation performance. In this study, a facile and environmentally friendly approach was used to produce a quartz sand filter material with pH-controllable wettability between superhydrophobicity/superoleophilicity and superhydrophilicity/underwater superoleophobicity. PEI/ZnO-SA/CS-coated quartz sand filter material (PEI/ZnO-SA/CS@QS) was fabricated by introducing ZnO nanoparticles , hydrophobic alkyl long chain, and amino group-rich hydrophilic groups into the surface of quartz sand filter material. Rich amino groups on the surface of the PEI/ZnO-SA/CS@QS has high adsorption capacity and separation efficiency of industrial Congo red dye and methylene blue . Before and after wettability conversion, the pH-controllable PEI/ZnO-SA/CS@QS was applied to separate oil/water mixtures and separate various water-in-oil emulsions and oil-in-water emulsions. In addition, PEI/ZnO-SA/CS@QS is recyclable, and 10 cycles of oil/water mixture separation of specific experiments in this study were performed, remaining unchangeable separation efficiency (>98.89%). PEI/ZnO-SA/CS@QS provides a new research direction for on-demand oil/water separation and modification of hard filter media. The resulted PEI/ZnO-SA/CS@QS has promising application prospects in on-demand oil/water separation and demulsification .

As a marker of cellular senescence and abnormal apoptosis, overexpression of β-galactosidase (SA-β-gal) is currently associated with many cancers, Alzheimer’s disease, cataracts, osteoporosis, and other diseases related to cellular senescence. SA-β-gal detection using surface-enhanced Raman scattering (SERS) is increasingly in the spotlight because of its acuteness and efficiency. This study aims to construct a sandwich-structure SERS substrate that can detect SA-β-gal in a sensitive, accurate, and cost-effective way, with a limit of detection of 4.79 × 10–5 U·mL–1. First, gold nanostars (Au NSs) were self-assembled on glass sheets, forming a monolayer gold surface, and the resulting substrate was defined as a gold nanoflake (Au-NF). Then 4-mercaptophenylboronic acid (PMBA) molecules were assembled on it. Lactose molecules served as a bridge between the substrate and SERS tags and were formed by Au NSs modified by PMBA and 4-aminothiophenol (PATP). When SA-β-gal came in contact with the functionalized Au-NF, with the SERS intensity at 1437 cm–1, the characteristic peak of 4,4′-dimercaptoazobenzene (DMAB) formed by PATP through laser irradiation decreased, indicating SA-β-gal activity. This structure allows the use of highly SERS-enhanced Au NSs while creating more hot spots between the SERS tags and substrate and improving the signal intensity without losing reproducibility and has potential in serum testing in the future.

Chemodynamic therapy (CDT) and photothermal therapy (PTT) have been widely studied as treatment alternatives to anbiotics to avoid the occurrence of bacterial resistance because of their negligible bacterial resistance and high antibacterial efficiencies. Herein, we developed an infection microenvironment-responsive nanogel (STF) to successfully achieve a PTT synergized CDT for bacterial infection. Through a one-step/pot method, STF nanotherapeutics consisting of Fe3+/sodium alginate (SA) based nanogels and Fe3+/tannic acid (TA) based metal–phenolic networks (MPNs) were conveniently prepared by the coordination-triggered simultaneous self-assembly of SA, TA, and Fe3+ ions. Afterward, their photothermal and catalytic performances were intensively investigated. Moreover, the sterilization effect of the STF nanogel was evaluated through in vitro and in vivo bactericidal assays. The STF nanogel exhibited a photothermal enhanced peroxidase-like activity because of the good photothermal effect of MPNs. In addition, its Fenton activity was further accelerated by an extra amount of Fe2+ derived from the degradation of Fe3+-chelating agents (SA) and reduction of TA. Together, the STF nanogel possessed a photothermal/Fe2+ dual-augmented catalytic property. In vitro and in vivo antibacterial assays proved its satisfactory bactericidal efficiency owing to PTT/Fe2+ dual-enhanced CDT. Our research findings suggested that the developed intelligent bactericidal nanogel has great potential to be used as an antibiotic alternative to avoid bacterial resistance in future clinical treatments.

The serious problem of carbon monoxide (CO) poisoning on the surface of Pt-based catalysts has long constrained the commercialization of proton exchange membrane fuel cells (PEMFCs). Regeneration of Pt sites by maintaining CO scavenging ability through precise construction of the surface and interface structure of the catalyst is the key to obtaining high-performance CO-resistant catalysts. Here, we used molybdenum carbide (MoC x ) as the support for Pt and introduced Ru single atoms (SA-Ru) at the Pt-MoC x interface to jointly decrease the CO adsorption strength on Pt. More importantly, the MoC x and SA-Ru are immune to CO poisoning, which continuously assists in the oxidation of adsorbed CO by generating oxygen species from water dissociation. These two effects combine to confer this anode catalyst (SA-Ru@Pt/MoC x ) remarkable CO tolerance and the ability to operate stably in fuel cell with high CO concentration (power output 85.5 mW cm −2 @20,000 ppm CO + H 2 – O 2 ), making it possible to directly use the cheap reformed hydrogen as the fuel for PEMFCs.
