To address the challenges of salt accumulation and limited evaporation rates in solar-driven interfacial evaporation systems under high-salinity environments, this study designed and fabricated an annular hydrogel evaporator with radially aligned channels based on the hydrophilic groups and cross-linked network properties of chitosan. This design significantly reduces material consumption while synergistically enhancing the evaporation rate and ambient energy harvesting capacity through a substantial increase in the Evaporation Area Index and intensified internal thermal convection, achieving an evaporation rate of 4.29 kg·m⁻²·h⁻¹ and a 6.7-fold improvement in volumetric evaporation efficiency. To further enhance long-term operational stability under extreme salinity, a top-active water supply strategy was introduced, which effectively clears concentrated salt ions at the evaporation interface via precise flow control, maintaining stable evaporation without salt deposition even in 25 wt% high-salinity brine. Outdoor experiments demonstrated that the system can not only continuously produce freshwater meeting WHO standards at a rate of 11.53–15.36 kg·m⁻²·d⁻¹, but also simultaneously achieve efficient brine concentration (concentration ratio: 1.16–2.29) and effective purification of heavy metals and organic dyes. Leveraging the core properties achieved through chemical structure modulation of chitosan—such as low evaporation enthalpy, high hydrophilicity, and stable salt rejection—this technology can be extended to concentration-dependent processes including brine mineral recovery and crystal purification, establishing a new paradigm for such applications. This design strategy also opens a new pathway for the broader application of carbohydrate polymers in sustainable water treatment and resource recovery.

为了解决高盐度环境下太阳能驱动界面蒸发系统中盐积累和蒸发速率有限的问题，本研究基于壳聚糖的亲水性基团和交联网络特性，设计并制造了具有径向排列通道的环状水凝胶蒸发器。该设计显著降低了材料消耗，同时通过大幅提高蒸发面积指数和增强内部热对流，协同提高了蒸发速率和环境能量收集能力，实现了4.29 kg·m−2·h−1的蒸发速率和6.7倍的体积蒸发效率。为了进一步提高在极端盐度下的长期运行稳定性，引入了一种顶部主动供水策略，通过精确的流量控制有效地清除蒸发界面上的浓缩盐离子，即使在25%的高盐度盐水中也能保持稳定的蒸发而不发生盐沉积。室外实验表明，该系统不仅能以11.53 ~ 15.36 kg·m−2·d−1的速率连续生产出符合WHO标准的淡水，同时还能实现高效的盐水浓缩（浓度比为1.16 ~ 2.29）和重金属、有机染料的有效净化。利用壳聚糖化学结构调节所获得的核心特性，如低蒸发焓、高亲水性和稳定的排盐性，该技术可以扩展到依赖浓度的过程，包括盐水矿物回收和晶体纯化，为此类应用建立了新的范例。这种设计策略也为碳水化合物聚合物在可持续水处理和资源回收中的更广泛应用开辟了新的途径。

In wound management, achieving rapid hemostasis while maintaining excellent biocompatibility, effectively preventing bacterial infection, and promoting tissue regeneration remains a major clinical challenge. In this study, we developed a multifunctional hydrogel (TA@SA/BG/Ca²⁺) based on a sodium alginate (SA)/tannic acid (TA)/Ca²⁺ dual crosslinking system uniformly loaded with boron-containing bioactive glass (BG). The hydrogel was constructed through synergistic TA@SA interactions combined with Ca²⁺ mediated ionic crosslinking to form a stable three-dimensional network, endowing the material with strong adhesion, enhanced mechanical properties, and integrated rapid hemostatic, broad-spectrum antibacterial, and antioxidant capabilities. Benefiting from its high-water content and superior swelling capacity, the hydrogel provides a favorable microenvironment for gradual BGs degradation, enabling sustained release of bioactive ions such as B³⁺, Si⁴⁺, and Ca²⁺. These ions synergistically suppress bacterial growth and inflammation while stimulating angiogenesis, collagen deposition, and tissue regeneration. In vivo experiments demonstrated that the hydrogel significantly accelerated wound closure in both full-thickness acute wounds and infected chronic wounds. This multifunctional hydrogel, integrating hemostatic, antibacterial, antioxidant, and pro-regenerative properties, shows promise for acute and chronic wound healing and provides a basis for further evaluation toward clinical translation.

在伤口管理中，如何在保持良好的生物相容性、有效预防细菌感染和促进组织再生的同时实现快速止血仍然是临床面临的主要挑战。在本研究中，我们开发了一种基于海藻酸钠(SA)/单宁酸(TA)/Ca2+双交联体系的多功能水凝胶（TA@SA/BG/Ca2+），均匀负载含硼生物活性玻璃（BG）。该水凝胶通过协同TA@SA相互作用结合Ca2+介导的离子交联形成稳定的三维网络，使材料具有较强的粘附性，增强的力学性能，并具有快速止血、广谱抗菌和抗氧化能力。得益于其高含水量和优越的溶胀能力，水凝胶为BGs的逐渐降解提供了有利的微环境，使生物活性离子如B3+， Si4+和Ca2+的持续释放成为可能。这些离子协同抑制细菌生长和炎症，同时刺激血管生成、胶原沉积和组织再生。体内实验表明，水凝胶在全层急性伤口和感染慢性伤口中均能显著加速伤口愈合。这种多功能水凝胶集止血、抗菌、抗氧化和促再生等特性于一体，有望用于急慢性伤口愈合，并为进一步评估临床转化提供了基础。

Enhancing the antibacterial activity of silver nanoparticles (AgNPs) against drug-resistant Mycobacterium tuberculosis remains an urgent need in the field of public health. In a previous study, we fabricated highly dispersible AgNPs using Konjac glucomannan (KGM), and the antibacterial activity of KGM-AgNPs against drug-resistant Mycobacterium tuberculosis did not meet the demand. In this study, we aimed to resolve the above problem by improving the homogeneity of KGM-AgNPs, using asymmetric flow field-flow fractionation (AF4) coupled with MALS, RI, UV, and a fraction collector. We obtained three fractions of KGM-AgNPs with high homogeneity, as evidenced by TEM, DLS, and Zeta-potential analyses, which demonstrated varying antibacterial activity against different drug-resistant Mycobacterium tuberculosis strains. Their antibacterial activity against Mycobacterium tuberculosis was closely related to their particle size, with smaller particles being more effective in killing multidrug-resistant strains. Overall, the antibacterial activity against drug-resistant Mycobacterium tuberculosis and homogeneity of silver nanoparticles could be significantly improved by AF4, which is crucial for their applications in life sciences and technology.

提高银纳米颗粒（AgNPs）对耐药结核分枝杆菌的抗菌活性仍然是公共卫生领域的迫切需要。在之前的研究中，我们利用魔芋葡甘露聚糖（KGM）制备了高分散性的AgNPs，但KGM-AgNPs对耐药结核分枝杆菌的抑菌活性不满足要求。在本研究中，我们旨在通过不对称流场-流分馏（AF4）与MALS、RI、UV和馏分收集器的耦合作用来改善KGM-AgNPs的均匀性，从而解决上述问题。通过TEM、DLS和zeta电位分析，我们获得了三种具有高均匀性的KGM-AgNPs组分，它们对不同耐药结核分枝杆菌菌株具有不同的抗菌活性。它们对结核分枝杆菌的抑菌活性与其颗粒大小密切相关，颗粒越小，对多重耐药菌株的杀灭效果越好。综上所述，AF4可以显著提高银纳米粒子对耐药结核分枝杆菌的抗菌活性和均匀性，这对其在生命科学和技术中的应用具有重要意义。

Industrial wastewater and oil spills are increasingly deteriorating the natural environment, driving demands for superhydrophobic oil-water separation materials. However, developing sustainable absorbents for oil spill remediation is challenging due to the typical trade-off between high absorption capacity and low mechanical robustness. Here, we present a biomass-derived ultralight foam using cellulose for environmental remediation, fabricated through integration of vinyltrimethoxysilane-modified Calotropis gigantea fiber (CGF) and microfibrillated cellulose (MFC). The hollow structure of CGF (pore size 8–15 μm) and the nanofibrous network of MFC synergistically combine to achieve ultralow density (6.12 ± 0.21 mg/cm³) and exceptional porosity (99.60 ± 0.14 %). The foam exhibits hydrophobicity (water contact angle of 141.2 ± 0.63°), adsorption capacity of 152.45 ± 5.65 g/g (for chloroform), oil uptake of 139.6 ± 3.17 g/g within 5 s (for dichloromethane), and separation flux of 29,257.9 ± 1491.3 L m⁻² h⁻¹ (for dichloromethane). Owing to the incorporation of CGF, it exhibits a 38.2 % higher oil absorption capacity than that of pure foam. The foam possesses temperature stability in a range of −10 °C to 60 °C, and maintains a repetitive separation efficiency of 99.06 ± 0.27 %. Demonstrated in a pump system for continuous oil-water separation, this foam offers a promising sustainable material for environmental remediation.

工业废水和石油泄漏日益恶化自然环境，推动了对超疏水油水分离材料的需求。然而，由于高吸收能力和低机械稳健性之间的典型权衡，开发可持续吸收剂用于溢油修复是具有挑战性的。在这里，我们提出了一种利用纤维素进行环境修复的生物质衍生超轻泡沫材料，该材料是通过乙烯基三甲氧基硅烷修饰的巨茶卡罗氏纤维（CGF）和微纤化纤维素（MFC）的整合而成的。CGF的中空结构（孔径8 ~ 15 μm）与MFC的纳米纤维网络协同作用，实现了超低密度（6.12±0.21 mg/cm3）和超高孔隙率（99.60±0.14%）。该泡沫具有疏水性（水接触角为141.2±0.63°），吸附量为152.45±5.65 g/g（氯仿），5 s内吸油量为139.6±3.17 g/g（二氯甲烷），分离通量为29,257.9±1491.3 L m−2 h−1（二氯甲烷）。由于CGF的加入，其吸油能力比纯泡沫提高了38.2%。该泡沫在−10℃~ 60℃范围内温度稳定，重复分离效率为99.06±0.27%。在连续油水分离的泵系统中，该泡沫为环境修复提供了一种有前途的可持续材料。

The use of hydrogel microparticles as granular hydrogels is an emerging approach in tissue engineering, where microparticles offer printability, injectability, and serve as scaffolds for cell culture. While culturing dermal fibroblasts for tissue engineering applications is well reported, there is limited research on culturing primary human pulmonary fibroblasts on granular hydrogels. In this study, we grafted RGD-peptides to alginate, formed microbeads, and investigated the ability of granular hydrogels to support the adhesion and growth of primary normal human dermal fibroblasts (NHDFs) and human pulmonary fibroblasts (HPFa). NHDFs adhered to linear RGD (linRGD)-alginate microbeads and spread on the bead surfaces with increased adhesion with increased peptide concentration (0.3–1.3 mM). In contrast, HPFa did not adhere to the linRGD-alginate microbeads. However, HPFa adhered and spread on flat linRGD-alginate gels, indicating that HPFa do respond to linRGD as an adhesion ligand. Supplementation of

resulted in cell adhesion to linRGD-alginate microbeads. Enhanced adhesion and spreading of HPFa to RGD-alginate microbeads were observed when using cyclic RGD. Hence, RGD-alginate microbeads is a promising material for structuring primary human dermal and pulmonary fibroblasts, showing the relevance of using alginate microbeads as scaffolds for 3D cultures with fibroblasts.

使用水凝胶微颗粒作为颗粒水凝胶是组织工程中的一种新兴方法，其中微颗粒具有可打印性，可注射性，并可作为细胞培养的支架。虽然培养真皮成纤维细胞用于组织工程的报道很多，但在颗粒状水凝胶上培养原代人肺成纤维细胞的研究有限。在这项研究中，我们将rgd -肽移植到海藻酸盐上，形成微球，并研究颗粒水凝胶支持原代正常人真皮成纤维细胞（NHDFs）和人肺成纤维细胞（HPFa）粘附和生长的能力。NHDFs粘附在线性RGD (linRGD)-海藻酸盐微球上，并随着肽浓度的增加而在微球表面扩散（0.3-1.3 mM）。相反，HPFa不粘附在linrgd -海藻酸微球上。然而，HPFa在扁平的linRGD-海藻酸凝胶上粘附和扩散，表明HPFa作为一种粘附配体确实对linRGD有反应。补充Mn2+导致细胞粘附到linrgd -海藻酸微球。当使用环状RGD时，观察到HPFa对RGD-海藻酸微球的粘附和扩散增强。因此，rgd -海藻酸微球是一种很有前途的材料，用于构建原代人皮肤和肺成纤维细胞，表明使用海藻酸微球作为成纤维细胞3D培养支架的相关性。

Unlike conventional inorganic metal-based fluorescent dopants, this research developed a cationic nanocellulose crystal (C-CNC) fluorescent agent that can physicochemically cross-link with cellulose fibers, endowing them with fluorescence for rapid and visual detection of iron ion (Fe³⁺) in aqueous. The C-CNC was synthesized using guanidine salt-based deep eutectic solvent (DES), which introduced π-π conjugation through guanidinium grafting at the C₂₋C₃ position of cellulose, endowing the C-CNC with remarkable blue fluorescence (450 nm). The C-CNC was firmly adhered to the fibers through hydrogen bonding and electrostatic interactions, yielding a multifunctional paper, which still exhibited strong fluorescence and mechanical strength even after being soaked in water for six months. Crucially, this paper exhibited particularly sensitive and selective fluorescence quenching for Fe³⁺ versus other ions, where the Fe³⁺ can coordinate with imine groups in C-CNCs, forming extended conjugated metal complexes that disrupt intramolecular charge transfer. The fluorescence intensity ratio (F₀/F) exhibited a remarkably linear correlation with Fe³⁺ concentration. Additionally, C-CNC endowed the paper with high Fe³⁺ sensitivity (LOD = 2.75 μM), antibacterial rate (~99%), strength (65.44 MPa), and degradation rate (91.66% within 45 days). In summary, this sensor exhibits good long-term stability in pure water systems, demonstrating potential for future environmental detection.

与传统的无机金属基荧光掺杂剂不同，本研究开发了一种阳离子纳米纤维素晶体（C-CNC）荧光剂，该荧光剂可以与纤维素纤维物理化学交联，使其具有荧光，可以快速和直观地检测水中的铁离子（Fe3+）。采用胍盐基深共晶溶剂（DES）合成C-CNC，在纤维素的C2 ~ C3位置通过胍接枝引入π-π共轭，使C-CNC具有显著的蓝色荧光（450 nm）。C-CNC通过氢键和静电相互作用牢固地粘附在纤维上，制成多功能纸，即使在水中浸泡6个月，仍表现出很强的荧光和机械强度。至关重要的是，本文显示了Fe3+相对于其他离子特别敏感和选择性的荧光猝灭，其中Fe3+可以与c - cnc中的亚胺基配合，形成扩展共轭金属配合物，破坏分子内电荷转移。荧光强度比（F0/F）与Fe3+浓度呈显著的线性相关。此外，C-CNC还赋予了该纸较高的Fe3+灵敏度（LOD = 2.75 μM）、抗菌率（~99%）、强度（65.44 MPa）和45 d内降解率（91.66%）。总之，该传感器在纯水系统中表现出良好的长期稳定性，显示出未来环境检测的潜力。

Creating highly efficient, cost-effective, and sustainable cellulose aerogel with elasticity and ordered structures is highly desired for purification of complex oily wastewater. Herein, we developed a “bottom-up” strategy to construct an elasticity cellulose micro/nano fibers (CMNF) aerogel without cross-linking agents, which employing cotton stalks-derived multiscale cellulose fibers network as a precursor. The precursor was fabricated via a combination of deep eutectic solvent (DES) pretreatment and ultrasound-assisted assembly approach. By regulating the dispersion states and interactions of the CMNF precursor, along with the growth behavior of ice crystals within it, we successfully constructed an aerogel with anisotropic “wall-septum” structure. After polydimethylsiloxane (PDMS) coating, aerogel exhibits stable superhydrophobicity (157.2° water contact angle) and exceptional adsorption capacity (37–92 g·g⁻¹). Moreover, the “wall-septum” structure endows aerogel with outstanding elasticity, the stress loss ratio of low density (16.16 mg·cm⁻³) aerogel was 4.21% after 50 cycles. Leveraging its outstanding oil-water selectivity, both free oil and emulsified oil can be separated. Notably, the separation flux for water-in-oil (w/o) emulsions exceeds 1811.53 (pump-driven) and 572.11 L·m⁻²·h⁻¹ (gravity-driven) with high separation efficiency (99.35%). PDMS/CMNF aerogels provides novel insights and prospects for exploring the preparation strategies of multiscale cellulose fiber aerogels which are multifunctional, self-supporting, structurally tunable, and superelastic.

创造高效、经济、可持续的纤维素气凝胶，具有弹性和有序的结构，是复杂含油废水净化的迫切需要。在此，我们开发了一种“自下而上”的策略来构建弹性纤维素微纳米纤维（CMNF）气凝胶，不需要交联剂，该策略采用棉秆衍生的多尺度纤维素纤维网络作为前驱体。采用深度共晶溶剂（DES）预处理和超声辅助组装相结合的方法制备前驱体。通过调节CMNF前体的色散状态和相互作用，以及其内部冰晶的生长行为，我们成功构建了具有各向异性“壁-隔膜”结构的气凝胶。经聚二甲基硅氧烷（PDMS）包覆后，气凝胶表现出稳定的超疏水性（157.2°水接触角）和优异的吸附能力（37 ~ 92 g·g−1）。低密度气凝胶（16.16 mg·cm−3）经过50次循环后，其应力损失率为4.21%。利用其出色的油水选择性，可以分离游离油和乳化油。值得注意的是，油包水（w/o）乳剂的分离通量分别超过1811.53（泵驱动）和572.11 L·m−2·h−1（重力驱动），分离效率高达99.35%。PDMS/CMNF气凝胶为探索多功能、自支撑、结构可调、超弹性的多尺度纤维素纤维气凝胶的制备策略提供了新的见解和前景。

Starch is a renewable, low-cost carbohydrate polymer, yet native thermoplastic starch is brittle and humidity-sensitive. This review critically synthesizes recent advances in chemical modification that enable high-performance starch bioplastics: esterification/crosslinking, oxidation, and hydrophobization. We develop structure–property maps linking degree of substitution or crosslink density to tensile strength, elongation, and barrier properties, and we differentiate solvent-cast films from reactive extruded TPS. Emphasis is placed on humidity-aware barrier reporting and, where possible, on quantitative synthesis. Processability is treated explicitly, typical windows for reactive extrusion and deep eutectic/ionic media are summarized together with conversion metrics. End-of-life is reviewed with a focus on standards and evidence—distinguishing visual disintegration from mineralization via CO₂ evolution. The article closes with checklists for minimum reporting and design charts that connect chemistry levers to target performance. By integrating chemistry, processing, and testing standards, the review provides decision-ready guidance for translating modified starch into scalable bioplastic formulations for packaging and coating applications.

With the increasing global prevalence of inflammatory bowel disease (IBD), the limitations of conventional interventions—such as prolonged toxicity and the emergence of resistance—underscore the need for innovative strategies for intervention. Pectic polysaccharides (PPs), complex soluble fermentable dietary fibres derived from plant sources, exhibit substantial potential in managing IBD owing to their multifaceted immunomodulatory and fermentative attributes. Although the regulatory activity of PPs in IBD is closely tied to their structural diversity, a thorough understanding of the causal structure-function relationship remains elusive. This review synthesizes structural characterization of PPs—encompassing fundamental units, side-chain branching, functional group modifications, molecular weight distribution and conformational characteristics—with their structure-guided modulatory mechanisms, emphasizing structure-activity relationships and precision intervention approaches. Additionally, this paper examines the current challenges and delineates future research directions for the application of PPs in alleviating IBD, with the objective of establishing a precise framework that connects their molecular structure, bioactivity, and intervention efficacy.

随着全球炎症性肠病（IBD）患病率的增加，传统干预措施的局限性，如长期毒性和耐药性的出现，强调了创新干预策略的必要性。果胶多糖（PPs）是一种从植物中提取的复杂可溶性可发酵膳食纤维，由于其多方面的免疫调节和发酵特性，在治疗IBD方面表现出巨大的潜力。尽管pp在IBD中的调控活性与其结构多样性密切相关，但对其因果结构-功能关系的透彻理解仍然难以捉摸。本文综述了pps的结构特征，包括基本单元、侧链分支、官能团修饰、分子量分布和构象特征，以及它们的结构导向调节机制，重点介绍了结构-活性关系和精确干预方法。此外，本文还分析了PPs在缓解IBD中的应用面临的挑战和未来的研究方向，旨在建立一个连接其分子结构、生物活性和干预效果的精确框架。
