多种不同肽的非共价共组装可能是生产多功能生物材料的有用途径。然而,迄今为止,此类材料几乎完全被研究为均质自组装体,其功能成分均匀分布在其超分子结构中。在这里,我们说明了对多种不同自组装肽混合的控制,进而提供了一种简单但强大的方法来调节这些材料的机械和生物特性。在β-片层原纤化水凝胶中,使用异双功能交联剂可以通过将带有不同反应基团的肽隔离到不同的原纤维群中来实现硬化的显着增加,从而有利于原纤维间的交联。此外,通过指定 2-D 和 3-D 自组装中 RGD 承载肽的混合,可以显着调节 HUVEC 和 NIH 3T3 细胞的生长。这种方法可以立即应用于形成稳定超分子结构的各种自组装系统。
The non-covalent co-assembly of multiple different peptides can be a useful route for producing multifunctional biomaterials. However, to date such materials have almost exclusively been investigated as homogeneous self-assemblies, having functional components uniformly distributed throughout their supramolecular structures. Here we illustrate control over the intermixing of multiple different self-assembling peptides, in turn providing a simple but powerful means for modulating these materials’ mechanical and biological properties. In beta-sheet fibrillizing hydrogels, significant increases in stiffening could be achieved using heterobifunctional cross-linkers by sequestering peptides bearing different reactive groups into distinct populations of fibrils, thus favoring inter-fibril cross-linking. Further, by specifying the intermixing of RGD-bearing peptides in 2-D and 3-D self-assemblies, the growth of HUVECs and NIH 3T3 cells could be significantly modulated. This approach may be immediately applicable towards a wide variety of self-assembling systems that form stable supramolecular structures.
