粘蛋白网络是通过糖蛋白与其他唾液蛋白的络合在口腔中形成的,产生水合润滑屏障。这些网络的功能与其结构、化学和机械特性有关。然而,由于这些属性是相互依赖的,因此很难弄清楚它们的相对重要性。在这里,我们展示了通过对聚合物蠕虫状胶束进行一系列互补冲洗来重建纤维状网络的能力,从而形成可以逐层沉积到任何表面上的 3 维 (3D) 多孔网络。在这项工作中,稳定性、结构和微生物捕获能力作为网络特性的函数进行了评估。研究发现,即使是由抗粘附聚合物聚乙二醇组成的网络,仅网络结构就足以捕获细菌。合成网络提供了一种优秀而简单的方法来独立表征粘蛋白网络特性(例如表面化学、刚度和孔径)。
Mucin networks are formed in the oral cavity by complexation of glycoproteins with other salivary proteins, yielding a hydrated lubricating barrier. The function of these networks is linked to their structural, chemical, and mechanical properties. Yet, as these properties are interdependent, it is difficult to tease out their relative importance. Here, we demonstrate the ability to recreate the fibrous like network through a series of complementary rinses of polymeric worm-like micelles, resulting in a 3-dimensional (3D) porous network that can be deposited layer-by-layer onto any surface. In this work, stability, structure, and microbial capture capabilities were evaluated as a function of network properties. It was found that network structure alone was sufficient for bacterial capture, even with networks composed of the adhesion-resistant polymer, poly(ethylene glycol). The synthetic networks provide an excellent, yet simple, means of independently characterizing mucin network properties (e.g., surface chemistry, stiffness, and pore size).
