Responsive Supramolecular Assemblies Based On Amphiphilic Polymers And Hybrid Materials, Longyu Li
Doctoral Dissertations
The design and synthesis of responsive supramolecular assemblies are of great interest due to their applications in a variety of areas such as drug delivery and sensing. We have developed a facile method to prepare self-crosslinking disulfide-based nanogels derived from an amphiphilic random copolymer containing a hydrophilic oligo-(ethylene glycol)-based side-chain functionality and a hydrophobic pyridyl disulfide functional group. This thesis first provides a concept of studying the influence of Hofmeister ions on the size and guest encapsulation stability of a polymeric nanogel. The size and core density of nanogel can be fine-tuned through the addition of both chaotropes and kosmotropes …

Design And Synthesis Of Polymeric Nanoparticles For Drug And Protein Delivery, Judy A. Ventura
Doctoral Dissertations
Nanoparticles are emerging as carriers in biological applications due to advances in their preparation, size control, surface modification and encapsulation capabilities. In addition, nanomaterials improve bioavailability by enhancing aqueous solubility of the guest molecule and increasing resistance time in the body. However, the delivery of guest molecules is still challenging due to the intrinsic characteristics of the guest molecule including large size and propensity to denature or degradation in the case of biomolecules and the encapsulation stability of the small guest molecules. Our group recently reported the preparation of self-cross-linked polymeric nanogels possessing surface functionalization capabilities. In this dissertation we …

Transferrin-Based Therapeutics And Analytical Methods To Characterize Them, Son N. Nguyen
Doctoral Dissertations
Modern development of medicine requires detailed characterization by state-of-the art analytical techniques that can be used to analyze covalent structure, conformations and protein-receptor interaction to quantitatively measure biodistribution of protein therapeutics. Mass spectrometry has already become an indispensable tool facilitating all stages of protein drug development. Particularly, this work has demonstrated the tremendous potential of electrospray ionization (ESI) mass spectrometry (MS) in this arena by providing invaluable information beyond mass measurement that can be used to optimize protein drug conjugate structures during early stages of development, and to further catalyze drug design efforts. Additionally, a new sensitive and selective method …
