This book was released on 2012 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this dissertation is the design, synthesis and characterization of hybrid functional biomaterials based on peptide-polymer conjugates for nanomedicine. Generating synthetic materials with properties comparable to or superior than those found in nature has been a "holy grail" for the materials community. Man-made materials are still rather simplistic when compared to the chemical and structural complexity of a cell. Peptide-polymer conjugates have the potential to combine the advantages of the biological and synthetic worlds- that is they can combine the precise chemical structure and diverse functionality of biomolecules with the stability and processibility of synthetic polymers. As a new family of soft matter, they may lead to materials with novel properties that have yet to be realized with either of the components alone. In order for peptide-polymer conjugates to reach their full potential as useful materials, the structure and function of the peptide should be maintained upon polymer conjugation. The success in achieving desirable, functional assemblies relies on fundamentally understanding the interactions between each building block and delicately balancing and manipulating these interactions to achieve targeted assemblies without interfering with designed structures and functionalities. Such fundamental studies of peptide-polymer interactions were investigated as the nature of the polymer (hydrophilic vs. hydrophobic) and the site of its conjugation (end-conjugation vs. side-conjugation) were varied. The fundamental knowledge gained was then applied to the design of amphiphiles that self-assemble to form stable functional micelles. The micelles exhibited exceptional monodispersity and long-term stability, which is atypical of self-assembled systems. Thus such micelles based on amphiphilic peptide-polymer conjugates may meet many current demands in nanomedicine, in particular for drug delivery of hydrophobic anti-cancer therapeutics. Lastly, biological evaluations were performed to investigate the potential of micelles as drug delivery vehicles. In vitro cell studies demonstrated that the micelles can be used as a delivery vehicle to tailor the cellular uptake, time release, and intracellular trafficking of drugs. In vivo biodistribution and pharmacokinetic experiments showed long blood circulation. This work demonstrates that peptide-polymer conjugates can be used as building blocks to generate hierarchical functional nanostructures with a wide range of applications, only one of which is drug delivery.

Download or read book Self assembly of Peptide polymer Conjugates for the Formation of Functional Biomaterials Via Molecular Dynamics Simulations written by Iris Wing Yin Fu and published by . This book was released on 2015 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Peptide-polymer conjugates are versatile molecular building blocks that can self-assemble into well-defined nanostructures with customizable biofunctionality and tunable physical properties for a wide range of biomedical applications. In this dissertation, two structural analogues of peptide-polymer conjugates are discussed: peptide amphiphiles and block copolymers with the difference between their respective domains tailored for specific applications. Self-assembly process of these peptide-polymer conjugates into different nanostructure morphologies is examined via molecular dynamics simulations using our recently developed integrated simulation package, called BioModi (Biomolecular Multiscale Models at UC Irvine). This simulation package consists of coarse-grained models that mimic realistic molecules and molecular interactions of amino acids, nucleic acids, and polymers, yet are simplified enough to allow molecular simulation of large systems over long time scales. For peptide amphiphiles, emphasis is placed on achieving a fine balance between the two distinct hydrophobic and hydrophilic domains to attain a supramolecular architecture that can serve as a biomimetic hydrogel scaffold for tissue engineering. The role of different environmental factors (e.g. temperature, pH, solvent) on the self-assembly behavior of peptide amphiphiles is elucidated in detail. Our simulations show that under optimal conditions, spontaneously self-assembly results in the formation of cylindrical nanofibers that can switch into spherical micelles in response to a small pH range as similarly observed by in vitro experiments. Moreover, phase diagrams are constructed to identify morphological transitions, and unique self-assembly kinetic mechanisms are characterized. Chemical modification of the peptide amphiphile sequence is investigated and contrasting structural characteristics are observed to correlate with differences in mechanical behavior of the resulting gel. For block copolymers, the inherent design utilizes a cationic polypeptide conjugated to a synthetic polymer that promotes favorable electrostatic interactions with nucleic acid fragments upon the formation of a polyionic complex as an effective gene carrier. Efficient complexation of block polymers with siRNA is determined via molecular dynamics simulations to be a function of the length of the polymer and the charge density of the system. Implementation of our newly developed coarse-grained models, BioModi, and insight gained from our simulations will provide key parameters to advance computer-aided design and development of innovative smart biomaterials.
