Investigating The Accumulation, Sub-Organ Distribution, And Biochemical Effects Of Nanomaterials Using Mass Spectrometry, Kristen Nicole Sikora
Investigating The Accumulation, Sub-Organ Distribution, And Biochemical Effects Of Nanomaterials Using Mass Spectrometry, Kristen Nicole Sikora
Doctoral Dissertations
Gold nanoparticles (AuNPs) are attractive materials for use in various biomedical applications, such as therapeutic delivery, due to their unique chemical properties and modular tunability. Mass spectrometry methods, including laser desorption/ionization mass spectrometry (LDI-MS) and inductively coupled plasma mass spectrometry (ICP-MS) have been successfully used to evaluate the distribution of AuNPs in complex biological systems. As new AuNP-based materials are developed for applications in therapeutic delivery, it is essential to simultaneously develop analytical techniques that can comprehensively assess their behavior in vivo. In this dissertation, novel mass spectrometric methods have been developed and utilized to evaluate the uptake, distribution, …

Hybridized Polymeric Nano-Assemblies: Key Insights Into Addressing Mdr Infections, Ryan Landis
Doctoral Dissertations
Multidrug-resistant (MDR) bacteria contribute to more than 700,000 annual deaths world-wide. Millions more suffer from limb amputations or face high healthcare treatment costs where prolonged and costly therapeutic regimens are used to counter MDR infections. While there is an international push to develop novel and more powerful antimicrobials to address the impending threat, one particularly interesting approach that has re-emerged are essential oils, phytochemical extracts derived from plant sources. While their antimicrobial activity demonstrates a promising avenue, their stability in aqueous media, limits their practical use in or on mammals. Inspired by the versatility of polymer nanotechnology and the sustainability …
Design And Synthesis Of Polymeric Nanoparticles For Drug And Protein Delivery, Judy A. Ventura
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 …
