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 …

Nature has designed magnificent responsive systems by constructing several interacting molecular level networks for the recognition and propagation of chemical and biochemical information. One of the eminent characteristics of these systems is their capability to quickly transduce molecular scale recognition events into macroscopic or visually observable responses. Inspired by these systems present in nature, we became interested in developing artificial responsive systems with similar capabilities. This dissertation will feature four such systems that employ amphiphilic oligomers and polymers which were chosen as the scaffolds because of their high thermodynamic stability, low critical aggregation concentrations, convenient handles to incorporate functional group …
