Curdlan is produced by fermentation of microorganisms, which is an insoluble β-(1 → 3)-D-glucans. To better effectively utilize native curdlan, firstly, a derivative from curdlan, carboxymethylated curdlan (CMCD), with different degrees of substitution (DS) DS ∼ 0.20, DS ∼ 0.43 and DS ∼ 0.82 were prepared in this study. Carboxymethylation increases solubility in water more than native curdlan. Moreover, CMCDs were investigated to be hydrolyzed by CcGluE, an endo-β-1 → 3-glucanase and generated the degradation products were oligosaccharides with degrees of polymerization (DP) mainly ranging from 2 to 7. CcGluE also showed high thermal and pH stability when CMCD ∼ 0.43 was used as a substrate. Then these oligosaccharides generated by different CMCDs were applied to Arabidopsis and the activity in inducing defense responses were detected after being treated by the pathogen of Pseudomonas syringae pv tomato DC3000 (Pst DC3000). CMCD (DS ∼ 0.20) degradation oligosaccharide (CMCD ∼ 0.20 OS) pre-treatment was the just one that significantly enhanced the disease resistance to Pst DC3000, which is mediated by the salicylic acid (SA) signaling pathway in plants. The findings offer new insights into the application of curdlan, demonstrating that carboxymethylation enhances its solubility in water. Additionally, the oligosaccharide products derived from CMCD degradation show promising prospects for controlling plant diseases in agriculture.

可得然由微生物发酵产生，是一种不溶于水的β-(1→3)-D-葡聚糖。为了更有效地利用原生可得然，本研究首先制备了不同取代度（DS）的可得然衍生物--羧甲基化可得然（CMCD），取代度分别为 DS ∼ 0.20、DS ∼ 0.43 和 DS ∼ 0.82。与原生可得然相比，羧甲基化可得然在水中的溶解度更高。此外，研究还发现，CMCD 可被 CcGluE（一种内-β-1 → 3-葡聚糖酶）水解，其降解产物为低聚糖，聚合度（DP）主要在 2 至 7 之间。当以 CMCD ∼ 0.43 为底物时，CcGluE 还表现出较高的热稳定性和 pH 稳定性。然后，将这些由不同 CMCD 生成的寡糖应用于拟南芥，并检测了其在经病原菌 Pseudomonas syringae pv tomato DC3000（Pst DC3000）处理后诱导防御反应的活性。CMCD（DS ∼ 0.20）降解寡糖（CMCD ∼ 0.20 OS）预处理是唯一能显著增强对 Pst DC3000 抗病性的预处理。研究结果为可得然的应用提供了新的见解，证明了羧甲基化可以提高可得然在水中的溶解度。此外，CMCD 降解产生的寡糖产品在农业中控制植物病害方面前景广阔。

The design of novel hybrid magnetoactive scaffolds based on biocompatible piezopolymers and magnetic nanoparticles is of interest for medicine, mainly for tissue regeneration, because application of an external either static or alternating magnetic field to cells that settled on a magnetoactive scaffold offers an opportunity for remote control of cellular functions. This study describes fabrication of electrospun magnetoactive poly(vinylidene fluoride-co-trifluoroethylene) [P(VDF-TrFE)] scaffolds highly doped with 20 wt% of magnetite nanoparticles modified with citric acid (Fe₃O₄-CA). The electrospun P(VDF-TrFE)/Fe₃O₄-CA scaffolds have defect-free morphology with a fiber diameter of approximately 1 μm and contain both an electroactive β-phase (predominantly) and a lesser amount of an γ-phase. A high content of uniformly distributed Fe₃O₄-CA nanoparticles within P(VDF-TrFE) fibrous scaffolds resulted in a high saturation magnetization of 12.1 emu/g and ferrimagnetic behavior of the composite P(VDF-TrFE)/Fe₃O₄-CA scaffolds. They were proved to be biocompatible with normal human cells: normal human fibroblasts and human mesenchymal stem cells adhered to the scaffold and retained their viability. According to high-throughput RNA-sequencing data, the adhesion of fibroblasts to the scaffolds upregulated genes related to key stages of tissue regeneration such as coagulation (genes THBD and SERPINB2) and wound healing (IL24, PDGFB, F3, and PLAU) and affected TGFβ, BMP, and Wnt signaling pathways. Alternating-magnetic-field exposure of the magnetoactive P(VDF-TrFE)/Fe₃O₄-CA scaffolds with fibroblasts settled on the surface activated extracellular and intracellular cell signaling pathways.

设计基于生物相容性压电聚合物和磁性纳米颗粒的新型混合磁活性支架对医学（主要用于组织再生）很有意义，因为向定居在磁活性支架上的细胞施加外部静态或交变磁场可提供远程控制细胞功能的机会。本研究介绍了电纺磁活性聚（偏氟乙烯-共三氟乙烯）[P(VDF-TrFE)]支架的制备方法，该支架高度掺杂了 20 wt% 经柠檬酸（Fe3O4-CA）修饰的磁铁矿纳米颗粒。电纺 P（VDF-TrFE）/Fe3O4-CA 支架具有无缺陷形态，纤维直径约为 1 μm，同时含有电活性 β 相（主要）和少量 γ 相。P（VDF-TrFE）纤维支架中均匀分布的高含量 Fe3O4-CA 纳米粒子使 P（VDF-TrFE）/Fe3O4-CA 复合支架的饱和磁化率高达 12.1 emu/g，并具有铁磁性。事实证明，它们与正常人体细胞具有生物相容性：正常人体成纤维细胞和人间质干细胞能粘附在支架上并保持活力。根据高通量 RNA 测序数据，成纤维细胞粘附到支架上会上调与组织再生关键阶段有关的基因，如凝血（基因 THBD 和 SERPINB2）和伤口愈合（IL24、PDGFB、F3 和 PLAU），并影响 TGFβ、BMP 和 Wnt 信号通路。磁活性 P(VDF-TrFE)/Fe3O4-CA支架表面沉积的成纤维细胞交变磁场暴露激活了细胞外和细胞内的信号通路。

Poly(vinylpyrrolidone) (PVP) hydrogels were obtained by green light irradiation of aqueous PVP/ammonium persulfate solutions modified with gold nanoparticles (AuNPs). The increase in temperature produced through the activation of the photothermal effect of AuNPs triggers the decomposition of ammonium persulfate producing radicals that, by attacking the polymer main chain and generating macro-radicals, induce the crosslinking of the polymer via recombination paths. Irradiation from the top of the solutions in an open configuration produced water evaporation and a concomitant increase in temperature during curing, giving rise to dry materials with high aspect ratio and moderate swelling anisotropy. Pads that reversibly adhere to different substrates, including human skin, were produced by simple contact of the final materials with water. Impregnation of gauze wound dressings with PVP-Au-ammonium persulfate dispersions, followed by direct “in situ” photothermal crosslinking, enabled the fabrication of supported functional pads with potential applications as reversible adhesive skin wound dressings. Infusion of the hydrogels with Rose Bengal (RB) provides the materials with photosensitizing properties useful for the photodynamic inactivation of Staphylococcus aureus. A decrease in cell viability of 99.9% was attained after 30 min of irradiation with a low-power green LED source, which demonstrates the efficient singlet oxygen production by RB in the hydrogels and paves the way towards the design of new stimulus-activated bactericidal supplies for biomedical uses.

通过绿光照射用金纳米粒子（AuNPs）修饰的聚乙烯吡咯烷酮（PVP）/过硫酸铵水溶液，获得了聚乙烯吡咯烷酮（PVP）水凝胶。通过激活 AuNPs 的光热效应产生的温度升高引发了过硫酸铵的分解，产生自由基，通过攻击聚合物主链和产生大自由基，诱导聚合物通过重组途径发生交联。在固化过程中，从开放结构的溶液顶部进行辐照会导致水分蒸发和温度随之升高，从而产生具有高纵横比和适度膨胀各向异性的干燥材料。只需将最终材料与水接触，就能制成可逆性粘附在不同基底（包括人体皮肤）上的垫子。用 PVP-Au- 过硫酸铵分散体浸渍纱布伤口敷料，然后直接进行 "原位 "光热交联，就能制造出具有可逆粘附皮肤伤口敷料应用潜力的支撑功能垫。用玫瑰红（RB）灌注水凝胶可使材料具有光敏特性，有助于光动力灭活金黄色葡萄球菌。用低功率绿色 LED 光源照射 30 分钟后，细胞存活率降低了 99.9%，这表明水凝胶中的玫瑰红能高效产生单线态氧，为设计用于生物医学用途的新型刺激活化杀菌用品铺平了道路。

Effective methods of multi-functionalization of nanomaterials are essential for fabricating effective targeted drug delivery systems. Herein, we disclose the fabrication of polymer brush-coated magnetic nanoparticles that could be functionalized with drugs and targeting ligands through orthogonal click reactions. In particular, polymers containing electron-rich furan groups as functionalization handles are grown from the surface of magnetic nanoparticles using the ‘graft-from’ approach. Furthermore, azide groups are installed at the chain end of polymer brushes to furnish an orthogonally functionalizable system. The attachment of maleimide-containing fluorescent dyes and cytotoxic drugs using the Diels-Alder reaction is demonstrated. Drug-conjugated nanoparticles functionalized with integrin-targeting peptide using the azide-alkyne cycloaddition reaction undergo preferential uptake in cancer cells and show dose-dependent cytotoxicity. We envision that the modularly functionalizable system disclosed here could target various cancer cells using an appropriate combination of drugs and targeting groups.

An economical and efficient approach for synthesizing high-fidelity PEG_n-Alds through a substitution and oxidation process has been developed, providing a new pathway for obtaining high-purity PEG_n-Alds, particularly addressing the issue of peroxidation and breakage of PEG main chains in the oxidation step. The synthesis of a series of high-fidelity PEG_n-Alds with different functional groups or topological structures further proves the versatility of this new method. Additionally, PEG_n-Alds also exhibit good biocompatibility, and potential ability to modify peptides and self-assembly to micelles, this lays a foundation for synthesizing high-quality drugs and developing novel therapeutics.

通过置换和氧化过程合成高保真 PEGn-Alds 的经济、高效方法已经开发出来，为获得高纯度 PEGn-Alds 提供了一条新途径，尤其解决了 PEG 主链在氧化步骤中过氧化和断裂的问题。一系列具有不同官能团或拓扑结构的高保真 PEGn-Alds 的合成进一步证明了这种新方法的多功能性。此外，PEGn-Alds 还具有良好的生物相容性、修饰肽和自组装成胶束的潜在能力，这为合成高质量药物和开发新型疗法奠定了基础。

Boronic acid (BA) moieties confer a variety of stimuli-response properties upon polymers. PISA is the most efficient technique for the preparation of core–shell nanoparticles (NPs), however aqueous dispersion PISA of free BA-containing monomers is complicated by the formation of the boroxine anhydride at the hydrophobic core. In the present work, dispersion reversible addition-fragmentation chain transfer (RAFT) copolymerization of a free BA-containing derivative of N-phenylacrylamide yields NP morphologies which are different to those formed from the equivalent PISA homopolymerization without BA. Depending on conditions, PISA results in spheres, rods, and worms with colloidal stability improved by using a higher fraction of the non-stimuli responsive monomer to give large compound micelles. Post-polymerization stimuli-response from the resultant PISA dispersion through hydrolysis of boroxine-rich copolymer NPs by dilution with the aqueous dispersion solvent or with water yields micron-sized worms, lamellae, and vesicles. Self-assembly to higher order morphologies is driven by the extent of hydrolysis. The resultant free BA-containing NPs becoming smaller and spherical upon basification and glucose addition.

硼酸（BA）分子赋予聚合物多种刺激响应特性。PISA 是制备核壳纳米粒子（NPs）最有效的技术，但含游离硼酸单体的水分散 PISA 会因疏水核形成硼氧酐而变得复杂。在本研究中，N-苯基丙烯酰胺的游离含 BA 衍生物的分散可逆加成-断裂链转移（RAFT）共聚产生的 NP 形貌不同于不含 BA 的等效 PISA 均聚形成的 NP 形貌。根据条件的不同，PISA 会产生球状、棒状和蠕虫状的 NP，通过使用较高比例的非刺激响应单体来产生大的复合胶束，可以提高胶体稳定性。用水性分散溶剂或水稀释富含硼氧的共聚物 NPs，水解产生的 PISA 分散体的聚合后刺激响应可产生微米大小的蠕虫、薄片和囊泡。高阶形态的自组装受水解程度的影响。由此产生的游离含 BA 的 NPs 在碱化和添加葡萄糖后会变小并呈球形。

A largely bio-based new bisphenol, namely, 4,4′-((3,4-dimethoxyphenyl)methylene)-bis(2-methoxyphenol) (DMBM) was synthesized by the reaction of veratraldehyde with guaiacol. DMBM and varying compositions of DMBM and bisphenol A were polycondensed with bis(4-fluorophenyl) sulfone to afford reasonably high molecular weight film-forming (co)poly(ether sulfone)s possessing built-in methoxyl groups. T₁₀ and T_g values of (co)poly(ether sulfone)s were in the range 382–478 °C and 171–187 °C, respectively indicating their good thermal stability and the values decreased with increase in mol % incorporation of DMBM. The methoxyl groups present in (co)poly (ether sulfone)s were quantitatively de-blocked resulting in the formation of corresponding polymers possessing pendant catechol moieties and free phenolic hydroxyl groups. By virtue of the presence of these functional moieties, (co)poly(ether sulfone)s are amenable for post-polymerization modifications, and exhibited properties such as antimicrobial (23 mm against Staphylococcus aureus and 18 mm against Escherichia coli)), antioxidant (72 % scavenger of free radicals), adhesive (2.24 MPa lap shear strength) and usefulness as redox-active agent in zinc-ion batteries. These data underscore the promise of DMBM as a versatile monomer of wider utility for the synthesis of functional (co)poly(ether sulfone)s capable of expanding their applicability beyond the conventional ones.

通过藜芦醛与愈创木酚的反应合成了一种主要以生物为基础的新型双酚，即 4,4′-((3,4-二甲氧基苯基)亚甲基)-双(2-甲氧基苯酚)（DMBM）。将 DMBM 以及不同成分的 DMBM 和双酚 A 与双（4-氟苯基）砜缩聚，可得到具有内置甲氧基的高分子量成膜（共）聚醚砜。共）聚（醚）砜的 T10 值和 Tg 值分别为 382-478 ℃ 和 171-187 ℃，这表明它们具有良好的热稳定性，而且随着 DMBM 含量的增加，T10 值和 Tg 值都有所下降。共）聚（醚砜）中的甲氧基被定量脱嵌，从而形成了具有邻苯二酚悬垂分子和游离酚羟基的相应聚合物。由于这些官能团的存在，（共）聚（醚砜）可以进行聚合后改性，并表现出抗菌（对金黄色葡萄球菌的抗菌能力为 23 mm，对大肠杆菌的抗菌能力为 18 mm）、抗氧化（72% 的自由基清除剂）、粘合（2.24 MPa 的搭接剪切强度）以及在锌离子电池中用作氧化还原活性剂等特性。这些数据表明，DMBM 是一种多功能单体，在合成功能性（共）聚（醚）砜方面具有更广泛的用途，能够将其应用范围扩展到传统单体之外。

In this research, we synthesized and analyzed the polymer 5-(5-(10-chlorodecyloxy)-2-methoxy-4-(5-methylthiophen-2-yl)phenyl)-5′-(2-(2-ethylhexyloxy)-5-methoxy-4-(5-methylthiophen-2-yl)phenyl)-2,2′-bithiophene (PTBT46). The polymer was dissolved in chloroform and subjected to gamma radiation doses ranging from 0 to 100 Gy (gray). We observed that PTBT46 can be doped with H+ions, as indicated by visible color changes, optical measurements, and a tenfold increase in conductivity. When analyzing PTBT46 in solution using THF (tetrahydrofuran) and chloroform, we found a notable solvent dependence. In chloroform, new absorption bands appeared at approximately 680 nm and 2630 nm after radiation doses of 25 to 100 Gy, which were not present in THF. These bands are attributed to polarons and bipolarons resulting from the doping process. Additionally, we observed a spectral “blue shift” with increasing H+concentration due to changes in molecular conjugation, without degradation of the polymer chain. This shift, confirmed by Fourier-transform infrared (FTIR) spectroscopy, is reversible and suggests potential applications in optoelectronic devices and advanced radiation sensors.

本研究合成并分析了聚合物 5-(5-(10-氯癸氧基)-2-甲氧基-4-(5-甲基噻吩-2-基)苯基)-5′-(2-(2-乙基己氧基)-5-甲氧基-4-(5-甲基噻吩-2-基)苯基)-2,2′-噻吩（PTBT46）。聚合物溶解在氯仿中，并接受 0 至 100 Gy 的伽马辐射剂量（灰色）。我们观察到 PTBT46 可以掺杂 H+离子，这表现在可见的颜色变化、光学测量以及电导率增加十倍。在使用 THF（四氢呋喃）和氯仿分析 PTBT46 的溶液时，我们发现了明显的溶剂依赖性。在氯仿中，辐射剂量为 25 至 100 Gy 后，在大约 680 nm 和 2630 nm 处出现了新的吸收带，而这些吸收带在 THF 中并不存在。这些吸收带归因于掺杂过程中产生的极子和双极子。此外，我们还观察到随着 H+ 浓度的增加，光谱会发生 "蓝移"，这是由于分子共轭发生了变化，而聚合物链并没有降解。傅立叶变换红外光谱（FTIR）证实，这种转变是可逆的，并表明它有可能应用于光电设备和先进的辐射传感器。
