Doctoral Dissertations

Personalized medicine requires the development of new technologies for controlled or targeted drug delivery. Three-dimensional (3D) printing and additive manufacturing techniques can be used to generate customized constructs for bioactive compound delivery. Nanotechnology in the form of nanoparticles, used as a stand-alone construct or for material enhancements, can significantly improve established biomaterials such as PMMA based bone cements or enable new technology to have enhanced capabilities. Combinations of the technologies can be used in such applications as infectious disease treatments, chemotherapeutic targeted drug delivery or targeted delivery of nearly any bioactive compound.

Chemotherapeutic or antibiotic enhanced 3D printing filaments were ...


Developent Of A Phospholipid Encapsulation Process For Quantum Dots To Be Used In Biologic Applications, Logan Grimes Jun 2014

Developent Of A Phospholipid Encapsulation Process For Quantum Dots To Be Used In Biologic Applications, Logan Grimes

Master's Theses and Project Reports

The American Cancer Society predicts that 1,665,540 people will be diagnosed with cancer, and 585,720 people will die from cancer in 2014. One of the most common types of cancer in the United States is skin cancer. Melanoma alone is predicted to account for 10,000 of the cancer related deaths in 2014. As a highly mobile and aggressive form of cancer, melanoma is difficult to fight once it has metastasized through the body. Early detection in such varieties of cancer is critical in improving survival rates in afflicted patients. Present methods of detection rely on visual ...


Encapsulation And Controlled Release Of Rhu-Erythropoietin From Chitosan Biopolymer Nanoparticles, Cody Bulmer Apr 2012

Encapsulation And Controlled Release Of Rhu-Erythropoietin From Chitosan Biopolymer Nanoparticles, Cody Bulmer

Electronic Thesis and Dissertation Repository

The objective of this research project was to develop a drug delivery system for recombinant human erythropoietin (rHu-EPO), a glycoprotein hormone used in the treatment of renal anaemia and chemotherapy induced anaemia, using the biopolymer chitosan as the base component. Two types of chitosan nanoparticles were produced through ionotropic gelation using flush mixing with either tripolyphosphate (TPP) or carrageenan polymer. Chitosan-TPP and chitosan-carrageenan nanoparticles were generated under a variety of conditions to evaluate the effects of chitosan concentration, chitosan to anion mass ratio and solution pH on the nanoparticle characteristics of particle diameter, surface charge and particle size distribution. A ...


Design And Evaluation Of "Pathogen-Mimicking" Polyanhydride Delivery Platforms For Drug And Vaccine Applications, Yashdeep Phanse Jan 2012

Design And Evaluation Of "Pathogen-Mimicking" Polyanhydride Delivery Platforms For Drug And Vaccine Applications, Yashdeep Phanse

Graduate Theses and Dissertations

Vaccines and antibiotics have had a profound impact on human and animal health in the last century. Despite their success, there are several disadvantages associated with current regimens, including multiple immunizations that result in poor patient compliance, high reactogenicity, unpleasant side effects, and poor efficacy against intracellular pathogens. In this regard, innovative delivery platforms can facilitate the development of effective single-dose treatment regimens to control emerging and re-emerging infectious diseases. The work presented in this dissertation describes how rational design principles can be successfully employed to develop targeted polyanhydride platforms for drug and vaccine delivery. Initial studies sought to define ...
