Engineering Of Gold Nanoparticles For Drug Delivery, Fangchao Liu
Engineering Of Gold Nanoparticles For Drug Delivery, Fangchao Liu
Wayne State University Dissertations
Due to their ease of synthesis, versatile surface chemistry, ease of imaging, and biocompatibility, gold nanoparticles (AuNPs) are employed as drug delivery devices in the treatment of respiratory problems associated with spinal cord injury (SCI). We have developed a method for the synthesis of a tripartite nanoconjugate comprised of an AuNP drug carrier chemically conjugated to a transporter protein (wheat germ agglutinin coupled to horseradish peroxidase or WGA-HRP) and to potent SCI drugs. The therapeutic efficacy and biodistribution were studied in a validated animal model. Our results show that a single administration of the nanoconjugate improved diaphragmatic activity at a …
Design Of Functional Dendrimer Nanocarriers And Their Formulations In Propellant-Based Inhalers For Pulmonary Drug Delivery, Lin Yang
Wayne State University Dissertations
This Dissertation focuses on addressing two of the major challenges in developing pressurized metered dose inhalers for pulmonary drug / gene delivery to and through the lungs. First challenge is to design biocompatible moieties for the steric stabilization of suspension formulations in HFO-based propellants. Using a combination of tools including ab initio calculation, molecular dynamics simulation and high pressure tensiometry, potential fluorocarbon-philic moieties were systematically screened. Surfactants with those chemistries as tail fragments were studied at the HFO|H2O interface for their ability to lower the interfacial tension at HFO|H2O interface. Selected surfactants were further optimized for surfactant balance by altering …
