Encapsulation Of Cationic Fluorescent Dyes And Photosensitizers Into The Nanoscopic Domains Of Poly(Ethylene Glycol)-B-Poly(Ε-Caprolactone) Micelles, Zhe Cao
Theses and Dissertations
This study describes an initial systematic investigation on the molecular determinants associated with the effective encapsulation (or lack thereof) of small cationic molecules into the nanoscopic domains of Poly(ethylene glycol)-b-poly(ε-caprolactone) micelles. Out of the seven model dyes investigated here (methylene blue, crystal violet, rhodamine 123, styryl 9M, HITC, DIR and Cardiogreen) only DiR and Cardiogreen were found to partition into the core region of the respective polymeric micelles with a high degree of efficiency. Evidences of weak interactions between styryl 9M and HITC with the corona region of these micelles were also found. No experimental evidences indicating any significant interaction …

Physical Property Control In Core/Shell Inorganic Nanostructures For Fluorescence And Magnetic Targeting Applications, Stephen K. Roberts
Theses and Dissertations
Nanomaterials show immense promise for the future in numerous areas of application. Properties that are unique from the bulk material and are tunable allow for innovation in material design. This thesis will focus on controlling the physical properties of core/shell nanostructures to enhance the utility of the materials.
The first focus is on the impact of different solvent mixtures during the shell growth phase of SILAR based core/shell quantum dot synthesis is studied. Gaining insight into the mechanism for SILAR growth of core/shell nanoparticles allows improved synthetic yields and precursor binding, providing enhanced control to synthesis of core/shell nanoparticles. The …
