Polymer-Based Strategies For Therapeutic Delivery To Bacterial Biofilms, Cheng-Hsuan Li
Polymer-Based Strategies For Therapeutic Delivery To Bacterial Biofilms, Cheng-Hsuan Li
Doctoral Dissertations
Bacterial infections are emerging threat to public health. Antibiotics once provided front-line treatments to bacterial infections; however, bacteria adapted to resist antibiotics through drug resistance mechanisms and biofilm formation. In this dissertation, I describe polymer-based strategies for therapeutic delivery as treatments of bacterial biofilm infections. Initially, I developed a functional polymer for delivering hydrophobic carvacrol (the primary constituent of oregano oil) to the bacterial biofilms. This strategy incorporates a cross-linking strategy to fabricate a robust yet biodegradable nanoemulsion, improving antimicrobial activity of carvacrol and overcoming antimicrobial resistance development. Next, I demonstrated that this functional polymer-based emulsion platform provides a general …

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 …
Alternative Methods For The Treatment Of Chemo-Resistant Cancers, Kaitlyn Wong
Alternative Methods For The Treatment Of Chemo-Resistant Cancers, Kaitlyn Wong
Doctoral Dissertations
Great strides have been made in cancer therapy in the past century, yet it remains one of the leading causes of death in the United States today. This work aimed to shed light on novel methods to treat a variety of aggressive and often chemo-resistant cancers both in vitro and in vivo. The first aim of this work was to evaluate the therapeutic efficacy of poly(methacryloyloxyethyl phosphorylcholine) (polyMPC) prodrugs compared to standard chemotherapeutic agents. Conjugation of polyMPC to drugs such as doxorubicin (Dox) can result in its improved solubility, prolonged half-life and therapeutic efficacy. PolyMPC and polyMPC-Dox (at a …
