Nanoassemblies presenting multivalent displays of biologically active carbohydrates are of significant interest for a wide array of biomedical applications ranging from drug delivery to immunotherapy. In this study, glycodendron–lipid hybrids were developed as a new and tunable class of dendritic amphiphiles. A modular synthesis was used to prepare dendron–lipid hybrids comprising distearylglycerol and 0 through 4th generation polyester dendrons with peripheral protected amines. Following deprotection of the amines, an isothiocyanate derivative of C-linked α-galactose (α-Gal) was conjugated to the dendron peripheries, affording amphiphiles with 1 to 16 α-Gal moieties. Self-assembly in …
Synthesis, Morphological Control, Dispersion Stabilization And In Situ Self-Assembly Of Noble Metal Nanostructures Using Multidentate Resorcinarene Surfactants, Sangbum Han
Chemistry & Biochemistry Theses & Dissertations
In this dissertation, a detailed investigation on the influence of various macrocyclic resorcinarene surfactants in determining the morphology, stabilization and self-assembly of mono- and bi- metallic nanoparticles was undertaken. Chapter 2 describes the influence of resorcinarene surfactants functionalized with amine- and thiol- headgroups in determining the morphology of monometallic Pt nanoparticles synthesized via the Brust-Schiffrin reaction. We found that while resorcinarene benzylthiol can lead to the formation of highly branched Pt nanostructures, resorcinarene amine can lead to the formation of anisotropic crystalline Pt nanoparticles. Further, we have evaluated the influence of resorcinarene ligands in determining the catalytic activity of these …

Stimuli Responsive Polymer Self-Assembly And Disassembly, Jiaming Zhuang
Doctoral Dissertations
Stimuli responsive polymer assemblies have been long investigated for drug application due to their flexibility for surface functionalization to achieve desired interfacial property and capability of acting as a host for payloads encapsulation. These interfacial and host-guest properties are very critical and need to be customized really depending on nature of cargos and specific delivery application. More importantly, these properties are always desired to be adaptable in different environments. For instance, adjustable interfacial property can facilitate the carrier to overcome a variety of different barriers before it reach the target while changeable host-guest property allows to selectively releasing the payload …
Supramolecular Strategies For The Generation Of Nanoparticle Assemblies And Biomolecular Thin Films, Bradley P. Duncan
Supramolecular Strategies For The Generation Of Nanoparticle Assemblies And Biomolecular Thin Films, Bradley P. Duncan
Doctoral Dissertations
The conceptual framework of supramolecular chemistry elucidates a powerful set of strategies for chemists to generate functional nanomaterials based on intermolecular forces. My research focused on tuning the molecular interactions of nanoscale components to create larger structures with enhanced properties. In one approach, I developed and optimized an additive-free, nanoimprint lithography-based methodology to generate stable thin films from a variety of proteins. The generalized process retains intrinsic properties of the protein as demonstrated by selective cellular adhesion. The heat and pressure of the nanoimprinting process induces slight structural reorganization of the peptide side chains to yield highly stable films held …

Conjugated Polymer-Based Biomaterials Through Controlled Self-Assembly, Megan Twomey
FIU Electronic Theses and Dissertations
Synthetic polymeric materials have gained significant use as biological materials (biomaterials) in biomedical and pharmaceutical applications. As a result, a demand for well-defined polymers with tunable properties has emerged. The synthetic versatility of polymeric biomaterials allows the opportunity to understand the structure-property relationship of materials and their cellular interactions. A novel class of polymeric biomaterials are conjugated polymers (CPs), which possess desirable physicochemical and excellent photophysical properties, including inherent fluorescence. The synthetic versatility of CPs allows easy modification of the conjugated backbone to tune emission and side chain structures to adjust biocompatibility through increased water solubility, controlled biodegradability, and incorporation …
