Polyelectrolyte Films(聚电解质薄膜)研究综述
Polyelectrolyte Films 聚电解质薄膜 - Here we develop a heterogeneous moisture-enabled electric generator (HMEG) based on a bilayer of polyelectrolyte films. [1] The design of layer-by-layer (LbL) polyelectrolyte films including nanoparticles is a growing field of innovation in a wide range of biomedical applications. [2] These results show the rich thermodynamics and kinetics of even monolayers and bilayers of polyelectrolyte films. [3] Here, a facile way is proposed to introduce periodic stratified porous structures into polyelectrolyte films. [4] Multilayer biopolyelectrolyte films are built from chitosan and casein by layer-by-layer deposition onto corona precharged poly(DL-lactic acid) substrate. [5] Surface based on polyelectrolytes functionalized with amino acids onto amino-terminated solid surfaces of silicon wafers was prepared, with the purpose of evaluate the chemical functionality of the polyelectrolyte films in adsorption and catalytic activity of an enzyme. [6] Although many approaches have been developed to encapsulate functional species into polyelectrolyte films, few of them can effectively control the final distribution of these ones. [7] These results indicate that it is possible to modulate the surface characteristics of polyelectrolyte films based on their chemical functionality and environmental parameters such as pH and ionic strength in order to evaluate their effect on cell adhesion. [8]在这里，我们开发了一种基于双层聚电解质薄膜的异质湿气发电机 (HMEG)。 [1] 包括纳米粒子在内的逐层 (LbL) 聚电解质薄膜的设计是广泛的生物医学应用中不断发展的创新领域。 [2] 这些结果表明即使是单层和双层聚电解质薄膜也具有丰富的热力学和动力学特性。 [3] 在这里，提出了一种将周期性分层多孔结构引入聚电解质膜的简便方法。 [4] 多层生物聚电解质薄膜由壳聚糖和酪蛋白通过逐层沉积到电晕预充电聚（DL-乳酸）基材上制成。 [5] 在硅片的氨基封端固体表面上制备了基于氨基酸功能化的聚电解质表面，目的是评估聚电解质膜对酶的吸附和催化活性的化学功能。 [6] 尽管已经开发了许多方法来将功能物质封装到聚电解质薄膜中，但其中很少有能够有效地控制这些物质的最终分布。 [7] 这些结果表明，可以根据聚电解质膜的化学功能和环境参数（如 pH 值和离子强度）来调节聚电解质膜的表面特性，以评估它们对细胞粘附的影响。 [8]
Thin Polyelectrolyte Films 聚电解质薄膜
Based on thin polyelectrolyte films of controlled stiffness, we investigated whether the presentation of four BMP members (2, 4, 7, 9) in a matrix-bound manner may differentially impact cell adhesion and bone differentiation of skeletal progenitors. [1] The resulting microspheres (diameter = 247 ± 13 μm) were then layered with thin polyelectrolyte films of hyaluronic acid (HA) and poly-L-lysine (PLL) to attempt to slow the diffusion of FITC-dextran out of the microspheres and the coating parameters were modified to modulate diffusion and release. [2]基于可控刚度的薄聚电解质膜，我们研究了四个 BMP 成员（2、4、7、9）以基质结合方式的呈现是否可能不同地影响骨骼祖细胞的细胞粘附和骨分化。 [1] 然后将所得微球体（直径 = 247 ± 13 μm）与透明质酸 (HA) 和聚-L-赖氨酸 (PLL) 的聚电解质薄膜分层，以试图减缓 FITC-葡聚糖从微球体和涂层中的扩散修改参数以调节扩散和释放。 [2]
