Polyelectrolyte Multilayers(聚电解质多层)研究综述
Polyelectrolyte Multilayers 聚电解质多层 - A polyelectrolyte multilayers (PEMs) primer was used to enhance the initial anchoring of the ZIF-8 seed crystals on the PU surface. [1] Gel beads loaded with Oph were synthesized from alginate, a naturally occurring biodegradable anionic polysaccharide, and coated with polyelectrolyte multilayers (from natural polyelectrolytes (chitosan and hyaluronic acid) and synthetic polyelectrolytes (poly(allylamine hydrochloride) and poly(styrene sulfonate)) or hybrid polyelectrolyte-graphene oxide multilayers. [2] FGF2 release from polyelectrolyte multilayers (PEMs) was measured and the data was fit to a simple degradation model, allowing for the determination of FGF2 concentrations between 2 and 4 days of culture time. [3] Polyelectrolyte multilayers (PEMs) are highly promising materials as selective separation layers on the inside of hollow fiber membranes. [4] The science behind the build-up mechanism of polyelectrolyte multilayers is important for developing devices for various engineering applications. [5] In particular, the surface properties of biomaterials are manipulated via the convenient introduction of amino groups to the ester-based polymers, the formation of polyelectrolyte multilayers, and the fabrication of topology and gradient cues, etc. [6] In this work, polyelectrolyte multilayers (PEMs) are prepared by alternating dip-coating of the negatively charged cellulose derivate carboxymethyl cellulose and a polycation, either polydiallyldimethylammonium chloride (PDADMAC) or chitosan (CHI). [7] The use of polyelectrolyte multilayers (PEMs) as emulsifying layers at an oil-water interface has significant potential to enhance emulsion application and function. [8] Polyelectrolyte complex (PEC) films such as polyelectrolyte multilayers have demonstrated excellent oxygen barrier properties, but unfortunately, the established layer-by-layer approaches are laborious and difficult to scale up. [9] With the contribution of both plasmonic Au film and polyelectrolyte multilayers, these findings underscore the guideline for creating selective SERS substrate for creatinine detection. [10] Among the unconventional approaches of supporting catalyst nanoparticles, the layer-by-layer assembly of polyelectrolyte multilayers for nanoparticle adsorption represents an easy and convenient method. [11] Titania nanotubes were fabricated via an anodization process and the surfaces were further modified with polyelectrolyte multilayers (PEMs) based on Tanfloc (a cationic tannin derivative) and glycosaminoglycans (heparin and hyaluronic acid). [12] Polyelectrolyte multilayers (PEMs) were prepared using the LbL technique from hydrophilic and amphiphilic derivatives of poly(allylamine hydrochloride) (PAH). [13] Polyelectrolyte multilayers are promising drug carriers with potential applications in the delivery of poorly soluble drugs. [14] HYPOTHESIS Polarity in polyelectrolyte multilayers (PEMs) may vary from the inner to the top layers of the film as the charge compensation of the layers is more effective inside the PEMs than in outer layers. [15] Polyelectrolyte multilayers (PEMs) were assembled by means of alternate electrostatic adsorption of polyanions and polycations using colloidal structure of polyelectrolyte complexes (PECs) as LbL building blocks. [16] Polyelectrolyte multilayers (PEMs) consisting of the polysaccharides hyaluronic acid (HA) as the polyanion and chitosan (Chi) as the polycation were prepared with layer-by-layer technique (LbL). [17] This work presents a simple methodology for coating small unilamellar liposomes bearing different degrees of positive charge with polyelectrolyte multilayers using the sequential layer-by-layer deposition method. [18] Polyelectrolyte multilayers (PEMs) coated on porous membrane supports have shown versatile opportunities for tailoring the resulting membrane characteristics. [19] Polyelectrolyte multilayers are versatile materials that are used in a large number of domains, including biomedical and environmental applications. [20] In our study, we consider standard polyvinyl chloride (PVC) catheter surfaces and compare their properties with the properties of the same surfaces coated with poly(diallyldimethylammonium chloride)/poly(sodium 4-styrenesulfonate) (PDADMA/PSS) polyelectrolyte multilayers. [21] We investigate the self-patterning of polyelectrolyte multilayers, poly(diallyldimethylammonium) (PDADMA)/poly(styrenesulfonate) (PSS)short. [22] Polyelectrolyte multilayers (PEMs) deposited on non lyophilized and lyophilized polylactic acid (PDLA) substrates were investigated. [23] The results prove a successful elimination of pharmaceutical contaminants, up to 84% from drinking water, by applying a combination of polyelectrolyte multilayers and ceramic membranes. [24] In the present work, we investigate the effect of surface chemistry on fouling of NF membranes based on polyelectrolyte multilayers (PEM), during the treatment of artificial produced water. [25] Polyelectrolyte multilayers have received broad interests in the fields of functional coatings due to their easy deposition procedure, environmentally friendly nature and wide sensitivities to manifold external stimuli. [26] These findings are in accordance with the results we obtained for polyelectrolyte multilayers and could be helpful for designing polyelectrolyte multilayers with tuned properties needed for various applications, primarily in the field of biomedicine. [27] In this work free-standing gels formed from gellan gum (GG) by solvent evaporation are coated with polysaccharide-based polyelectrolyte multilayers, using the layer-by-layer approach. [28] Polyelectrolyte multilayers (PEMs) based on poly-llysine (PLL) and complexes of poly(acrylic acid) (PAA) and gentamicin have been fabricated here applying the layer-by-layer (LbL) technique. [29] The diffusion of sodium dithionite (S2O42-) through polyelectrolyte multilayers of poly(diallyl dimethyl ammonium chloride) (PDADMAC)/poly(styrene sodium sulfonate) (PSS) assembled on colloidal particles with the layer-by-layer technique is studied by means of flow cytometry and quenching assay. [30] Thus, it can be concluded that the presence of polyelectrolyte multilayers on the membrane surface has successfully formed a stable nano-range membrane with the same desired permeability even after back-flushing. [31] These assays are encapsulated in microdomains bounded by polyelectrolyte multilayers (PEMs), permeable to the target but impermeable to proteins. [32] Surface forces are used to investigate the polymer conformation and the surface charge of polyelectrolyte multilayers. [33] Polyelectrolyte multilayers (PEMs) can be constructed using the layer-by-layer (LbL) technique and serve as a depot for bioactive substances, which can then be released in a controlled manner. [34] The encapsulation was carried out by (1) compaction of T4 DNA with multivalent cations, (2) entrapment of DNA condensates into micrometer-sized CaCO3 beads, (3) assembly of polyelectrolyte multilayers on a bead surface, and (4) dissolution of beads resulting in DNA unfolding and release. [35] Polyelectrolyte multilayers (PEMs) consisting of hyaluronic acid (HA) and chitosan (Ch) are extensively studied for biomedical applications and suppress bacterial and protein attachment. [36] [10–13] Polyelectrolyte multilayers (PEMs) are fabricated by the so-called layer-by-layer (LbL) technique. [37] These assays are encapsulated in "free" form within microdomains bounded by polyelectrolyte multilayers (PEMs), permeable to the target but impermeable to proteins. [38] On rough substrates of Au coated with polyelectrolyte multilayers, the liposomes were adsorbed intact on the surface. [39] HYPOTHESIS The application of an external electric Field (E-Field) to control layer-by-layer (LBL) growth of polyelectrolyte multilayers (PEM) typically involves hydrolysis of the water at the electrodes. [40] In this work, a controlled release composite with IPBC for inhibition of mold and stain fungi was prepared using enlarged halloysite nanotubes (HNTs) with layer-by-layer (LbL) assembly of polyelectrolyte multilayers. [41] Polyelectrolyte multilayers (PEMs) are widely used as drug delivery systems, but still remain challenging for their small drug immobilizing capacity. [42] To endow Ti implant with self-defensive antibacterial properties and desirable osteo/angio-genic differentiation potentials, hyaluronic acid (HA)-gentamicin (Gen) conjugates (HA-Gen) and chitosan (Chi) polyelectrolyte multilayers were constructed on deferoxamine (DFO) loaded titania nanotubes (TNT) substrates via layer-by-layer (LBL) assembly technique, termed as TNT/DFO/HA-Gen. [43] Polyelectrolyte multilayers (PEMs) have significant potential in many technologies, yet the dynamics of the constituent polymer chains remains poorly understood. [44] Polyelectrolyte multilayers (PEM) based microcontainers (MCs) require several days production time, while MCs composed out of polylactic acid (PLA) are entirely hydrophobic, offering no functionality. [45] Polyelectrolyte multilayers (PEMs) via alternate deposition of poly (allylamine hydrochloride) (PAH) and poly (sodium-4-styrenesulfonate) (PSS) were used to culture NSPCs. [46] Herein, polyelectrolyte multilayers have been explored as bactericidal coatings with controlled antitumor drug release. [47] Polyelectrolyte multilayers (PEMs) assembled layer-by-layer have emerged as functional polymer films that are both stable and capable of containing drug molecules for controlled release applications. [48] Polyelectrolyte multilayers (PEMs) are a category of materials commonly used as coatings on surfaces that interact with cells. [49] In this contribution, our aim was to build up a highly stable and reproducible enzyme-based host–guest carrier from maltose-modified hyperbranched poly(ethylene imine) (PEI-Mal-C) and polyelectrolyte multilayers (PEMs) to monitor glucose level. [50]聚电解质多层 (PEM) 底漆用于增强 ZIF-8 晶种在 PU 表面上的初始锚定。 [1] 载有 Oph 的凝胶珠由藻酸盐(一种天然存在的可生物降解的阴离子多糖)合成,并涂有聚电解质多层(来自天然聚电解质(壳聚糖和透明质酸)和合成聚电解质(聚(烯丙胺盐酸盐)和聚(苯乙烯磺酸盐))或混合聚电解质-氧化石墨烯多层。 [2] 测量了聚电解质多层 (PEM) 释放的 FGF2,并将数据拟合到一个简单的降解模型,从而可以确定培养 2 到 4 天之间的 FGF2 浓度。 [3] 聚电解质多层 (PEM) 是非常有前景的材料,可作为中空纤维膜内部的选择性分离层。 [4] 聚电解质多层构建机制背后的科学对于开发用于各种工程应用的设备非常重要。 [5] 特别是,生物材料的表面性质通过方便地将氨基引入酯基聚合物、形成聚电解质多层、制造拓扑和梯度线索等来控制生物材料的表面性质。 [6] 在这项工作中,通过交替浸涂带负电荷的纤维素衍生物羧甲基纤维素和聚二烯丙基二甲基氯化铵 (PDADMAC) 或壳聚糖 (CHI) 来制备聚电解质多层膜 (PEM)。 [7] 在油水界面使用聚电解质多层 (PEM) 作为乳化层具有增强乳液应用和功能的巨大潜力。 [8] 聚电解质复合物 (PEC) 薄膜,如聚电解质多层膜,已表现出优异的氧气阻隔性能,但不幸的是,已建立的逐层方法费力且难以扩大规模。 [9] 由于等离子金膜和聚电解质多层膜的贡献,这些发现强调了为肌酐检测创建选择性 SERS 底物的指导方针。 [10] 在负载催化剂纳米粒子的非常规方法中,用于纳米粒子吸附的聚电解质多层的逐层组装代表了一种简单方便的方法。 [11] 二氧化钛纳米管通过阳极氧化工艺制造,并用基于 Tanfloc(阳离子单宁衍生物)和糖胺聚糖(肝素和透明质酸)的聚电解质多层 (PEM) 进一步改性表面。 [12] 使用 LbL 技术从聚 (烯丙胺盐酸盐) (PAH) 的亲水性和两亲性衍生物制备聚电解质多层 (PEM)。 [13] 聚电解质多层膜是有前途的药物载体,在输送难溶性药物方面具有潜在应用。 [14] 假设 聚电解质多层 (PEM) 中的极性可能会从薄膜的内层到顶层有所不同,因为这些层的电荷补偿在 PEM 内部比在外层中更有效。 [15] 使用聚电解质复合物 (PEC) 的胶体结构作为 LbL 构件,通过聚阴离子和聚阳离子的交替静电吸附来组装聚电解质多层 (PEM)。 [16] 采用逐层技术(LbL)制备了由多糖透明质酸(HA)作为聚阴离子和壳聚糖(Chi)作为聚阳离子组成的聚电解质多层(PEM)。 [17] 这项工作提出了一种简单的方法,用于使用顺序逐层沉积方法用聚电解质多层涂层带有不同程度正电荷的小单层脂质体。 [18] 涂覆在多孔膜载体上的聚电解质多层 (PEM) 已显示出调整所得膜特性的多种机会。 [19] 聚电解质多层是一种用途广泛的材料,可用于许多领域,包括生物医学和环境应用。 [20] 在我们的研究中,我们考虑了标准聚氯乙烯 (PVC) 导管表面,并将它们的性能与涂有聚 (二烯丙基二甲基氯化铵)/聚 (4-苯乙烯磺酸钠) (PDADMA/PSS) 聚电解质多层的相同表面的性能进行了比较。 [21] 我们研究了聚电解质多层的自图案化,聚(二烯丙基二甲基铵)(PDADMA)/聚(苯乙烯磺酸盐)(PSS)short。 [22] 研究了沉积在非冻干和冻干聚乳酸 (PDLA) 基底上的聚电解质多层 (PEM)。 [23] 结果证明,通过应用聚电解质多层膜和陶瓷膜的组合,可成功消除饮用水中高达 84% 的药物污染物。 [24] 在目前的工作中,我们研究了在人工采出水处理过程中,表面化学对基于聚电解质多层 (PEM) 的纳滤膜污染的影响。 [25] 聚电解质多层膜由于其易于沉积过程、环保性质和对多种外部刺激的广泛敏感性而在功能涂层领域受到广泛关注。 [26] 这些发现与我们对聚电解质多层获得的结果一致,并且可能有助于设计具有各种应用所需的调谐特性的聚电解质多层,主要是在生物医学领域。 [27] 在这项工作中,通过溶剂蒸发由结冷胶 (GG) 形成的自支撑凝胶采用逐层方法涂有基于多糖的聚电解质多层膜。 [28] 基于聚赖氨酸 (PLL) 和聚丙烯酸 (PAA) 和庆大霉素复合物的聚电解质多层 (PEM) 已在此处应用逐层 (LbL) 技术制造。 [29] 连二亚硫酸钠 (S2O42-) 通过聚(二烯丙基二甲基氯化铵)(PDADMAC)/聚(苯乙烯磺酸钠)(PSS)多层组装在胶体颗粒上的聚电解质扩散,通过逐层技术研究流式细胞术和猝灭测定。 [30] 因此,可以得出结论,即使在反冲洗之后,膜表面上存在的聚电解质多层已经成功地形成了具有相同所需渗透性的稳定纳米级膜。 [31] 这些测定被封装在由聚电解质多层 (PEM) 界定的微域中,可渗透靶标但不渗透蛋白质。 [32] 表面力用于研究聚合物构象和聚电解质多层的表面电荷。 [33] 聚电解质多层 (PEM) 可以使用逐层 (LbL) 技术构建,并用作生物活性物质的储存库,然后可以以受控方式释放。 [34] 通过 (1) T4 DNA 与多价阳离子的压实,(2) 将 DNA 缩合物捕获到微米大小的 CaCO3 珠粒中,(3) 在珠粒表面组装聚电解质多层,以及 (4) 珠粒的溶解,进行封装导致 DNA 展开和释放。 [35] 由透明质酸 (HA) 和壳聚糖 (Ch) 组成的聚电解质多层 (PEM) 被广泛研究用于生物医学应用并抑制细菌和蛋白质的附着。 [36] [10-13] 聚电解质多层 (PEM) 是通过所谓的逐层 (LbL) 技术制造的。 [37] 这些测定以“游离”形式封装在由聚电解质多层 (PEM) 界定的微域内,可渗透靶标但不渗透蛋白质。 [38] 在涂有聚电解质多层的 Au 粗糙基底上,脂质体完整地吸附在表面上。 [39] 假设 应用外部电场 (E-Field) 来控制聚电解质多层 (PEM) 的逐层 (LBL) 生长通常涉及电极处水的水解。 [40] 在这项工作中,使用具有聚电解质多层层逐层 (LbL) 组装的扩大的埃洛石纳米管 (HNT) 制备了一种用于抑制霉菌和污渍真菌的控释复合材料与 IPBC。 [41] 聚电解质多层 (PEM) 被广泛用作药物输送系统,但仍因其较小的药物固定能力而具有挑战性。 [42] 为了赋予钛植入物自卫抗菌特性和理想的骨/血管生成分化潜能,在去铁胺 (DFO) 上构建了透明质酸 (HA)-庆大霉素 (Gen) 缀合物 (HA-Gen) 和壳聚糖 (Chi) 聚电解质多层膜通过逐层(LBL)组装技术加载二氧化钛纳米管(TNT)基板,称为TNT / DFO / HA-Gen。 [43] 聚电解质多层 (PEM) 在许多技术中具有巨大的潜力,但其组成聚合物链的动力学仍然知之甚少。 [44] 基于聚电解质多层 (PEM) 的微容器 (MC) 需要几天的生产时间,而由聚乳酸 (PLA) 组成的 MC 完全疏水,不提供任何功能。 [45] 通过交替沉积聚 (烯丙胺盐酸盐) (PAH) 和聚 (4-苯乙烯磺酸钠) (PSS) 的聚电解质多层 (PEM) 用于培养 NSPC。 [46] 在此,聚电解质多层已被探索为具有受控抗肿瘤药物释放的杀菌涂层。 [47] 逐层组装的聚电解质多层 (PEM) 已成为功能性聚合物薄膜,既稳定又能够包含药物分子,用于控释应用。 [48] 聚电解质多层 (PEM) 是一类通常用作与细胞相互作用的表面涂层的材料。 [49] 在这项贡献中,我们的目标是从麦芽糖改性的超支化聚(乙烯亚胺)(PEI-Mal-C)和聚电解质多层(PEM)中建立一种高度稳定和可重复的基于酶的主客体载体,以监测葡萄糖水平。 [50]
