Self-assembling biomaterials: molecular design, characterization and application in biology and medicine provides a comprehensive coverage on an emerging area of biomaterials science, spanning from conceptual designs to advanced characterization tools and applications of self-assembling biomaterials, and compiling the recent developments in the field. Molecular self-assembly, the autonomous organization of molecules, is ubiquitous in living organisms and intrinsic to biological structures and function. Not surprisingly, the exciting field of engineering artificial self-assembling biomaterials often finds inspiration in Biology. More important, materials that self-assemble speak the language of life and can be designed to seamlessly integrate with the biological environment, offering unique engineering opportunities in bionanotechnology. The book is divided in five parts, comprising design of molecular building blocks for self-assembly; exclusive features of self-assembling biomaterials; specific methods and techniques to predict, investigate and characterize self-assembly and formed assemblies; different approaches for controlling self-assembly across multiple length scales and the nano/micro/macroscopic properties of biomaterials; diverse range of applications in biomedicine, including drug delivery, theranostics, cell culture and tissue regeneration.

This thesis deals with the development of novel strategies for self-assembling biomaterials based on short beta-sheet fibril-forming peptides. These materials are potentially useful for a variety of biomedical applications, including tissue engineering and controlled drug release, and several aspects of these materials have been explored in this thesis in an effort to improve their clinical utility. First, a strategy for rapidly and uniformly triggering peptide self-assembly was developed. Stimulus-sensitive liposomes were utilized to sequester salts and release them in response to stimuli such as warming to body temperature or exposure to near infra-red light. Triggered salt release in turn initiated rapid self-assembly of extravesicular peptide and the transformation of the peptide/liposome suspension from a solution to a hydrogel. We show that peptide self-assembly can be rapidly, uniformly, and specifically triggered, with the storage modulus increasing three orders of magnitude upon triggering. This rapid triggering strategy is potentially useful for injectable biomaterial applications. In the second research thrust, a self-assembling peptide was developed that also possessed enzymatic activity for the cross-linking enzyme tissue transglutaminase. We then utilized tissue transglutaminase to conjugate cell-interactive peptides to the self-assembled structure and investigated cell attachment to these functionalized scaffolds. Such a strategy is potentially useful for designing biospecific self-assembling scaffolds for tissue engineering or wound healing. In the final research focus, to modulate the nanostructure of the self-assembled fibrillar structures, we developed a series of self-assembling polyethylene glycol-conjugated peptides. We found that polyethylene glycol conjugation significantly altered fibril morphology, including width, length, and degree of lateral aggregation. As previous beta-sheet fibrillar self-assembled materials have shown particular intransigence to such modification of the fibrillar structure, this strategy may be a useful route for tailoring the physical properties of these materials. As a whole, the strategies developed in this thesis address previous shortcomings of beta-sheet peptide-based self-assembling materials in an effort to bring them closer to clinical application.

The objective of this thesis was to design self-assembling biomaterials whose physical and biological properties can be systematically adjusted to modulate cell growth and differentiation. The intended applications of these biomaterials include defined 3D cell culture scaffolds as well as coatings for existing prosthetics. The complex and dynamic nature of extracellular matrices necessitates the precise integration and adjustment of multiple physical, chemical, and biological features within engineered biomaterials, but this has been challenging for previous scaffolds owing to the fact that these features tend not to be adjustable independently. Instead, these properties tend to be conflated and entangled, limiting the ability to systematically engineer scaffolds with multiple components. As a step towards addressing this issue, this thesis describes the development of a modular self-assembling biomaterial system capable of incorporating multiple physical or biological functions into precisely defined biomaterials without affecting other material properties. Three families of different biological and physical functionalities were designed, synthesized, and investigated: those that modulate matrix mechanics, those that mediate cell-matrix binding, and those that can release soluble effector molecules. All materials were based on a short, synthetic, self-assembling peptide sequence, Q11, which formed self-supporting hydrogels in physiological conditions. To independently modulate matrix mechanics, Q11 derivatives were developed possessing chemoselective functional groups that could be polymerized via native chemical ligation. This method produced significantly stiffened gels, which also significantly enhanced endothelial cell proliferation in an independent manner. To develop modular self-assembling ligand-bearing peptides, endothelial cell-interactive ligands, RGDS, REDV, IKVAV, and YIGSR amino acid sequences were added to the N-terminus of Q11 (X-Q11). The incorporation of X-Q11 into hydrogels was quantitative and did not significantly alter stiffness when different ligands were included in the hydrogels. The ligands were physically presented on the surface of fibrils, retained their biological activities, and interacted with cell surface receptors to modulate endothelial cell behaviors. To develop Q11 derivatives capable of releasing soluble effectors, Q11 peptides were synthesized containing a nitric oxide (NO) donor compound. The conjugation efficiency was about 88%, and fibril morphologies were not significantly altered by the NO donor compound, allowing quantitative incorporation of this peptide into Q11 hydrogels. The last stage of the project employed a statistical method, design of experiments, to capitalize upon the modularity of the developed co-assembling matrices, with the purpose of maximizing the growth of endothelial cells on the materials. Through several rounds of multifactorial experimentation, an optimal formulation of multiple peptides was determined, resulting in endothelial cell attachment and proliferation comparable to the native matrix protein, fibronectin. Such a calculation of an optimal formulation would be prohibitively costly, both in terms of time and materials, for conventional biomaterials not constructed in a modular fashion. These results suggested that modular Q11-based self-assembling systems enable facile manipulation of multiple factors, allowing the efficient targeting of a desired response, in this case endothelial cell growth. This approach should allow for the systematic design of biomaterials for a wide range of applications, without relying on ad hoc strategies.

Self-assembled nanostructures based on peptides and proteins have been investigated and presented as biomaterials with an impressive potential for a broad range of applications such as microfabrication, biosensing platforms, drug delivery systems, bioelectronics and tissue reparation. Through self-assembly peptides can give rise to a range of well-defined nanostructures such as nanotubes, nanofibers, nanoparticles, nanotapes, gels and nanorods. However, there are challenges when trying to integrate these biological nanostructures in the development of sensing devices or drug-delivery systems – challenges such as controlling the size during synthesis, the stability in liquid environments and manipulation. In "Micro and Nanofabrication Using Self-assembled Biological Nanostructures" the options and challenges when using self-assembled peptide nanostructures in micro and nanofabrication are discussed. The publication covers different ways to manipulate, deposit and immobilize on specific locations these biological nanostructures in order to use them in the fabrication of new structures or as part of biosensing platforms. Examples where researchers used biological nanostructures for those types of applications are provided. Finally, future applications are discussed as well as parameters to accelerate and expand the use of these biological building blocks in nano- and micro-fabrication processes by taking advantage of their impressive properties such as low-cost and short synthesis time.
