Assessment Of Catalytic Function Of Gold Nanorod-Bound Tempo Under Nir Irradiation, Kristi L. St. Clair
Assessment Of Catalytic Function Of Gold Nanorod-Bound Tempo Under Nir Irradiation, Kristi L. St. Clair
Honors College Theses
Gold nanoparticles are of interest to a number of fields due to their size-dependent optical properties, high stability, and large surface area. The combination of these properties allows for a variety of uses including photothermal therapy, drug delivery and catalysis. Gold nanorods (GNR) absorb light of a given wavelength which stimulates the oscillation of electrons on the surface and is known as the surface plasmon resonance effect. The localized heating of rods via irradiation may cause enhanced effectiveness of an attached organic catalyst which allows the oxidation of alcohols to occur at room temperature. Previously, similar catalytic systems required high …
Polyethylene Glycol Containing Rompolymers For The Modification Of Neuro-Protective Hemoglobin, Andrea L. Mccollum
Polyethylene Glycol Containing Rompolymers For The Modification Of Neuro-Protective Hemoglobin, Andrea L. Mccollum
Honors College Theses
Polyethylene glycol (PEG) has shown the ability to improve compatibility when used in combination with cell-free hemoglobin in the treatment of traumatic brain injuries. It has been demonstrated that the covalently bonded PEG increases the hydrodynamic radius of the hemoglobin and hence generates a physical barrier while slowing down the oxygen delivery of the strongly oxidative hemoglobin. In this context, I have been working on the development of synthetic pathways to incorporate PEG into monomers and polymers through both direct modification of (7-oxa)norbornene derivatives and post polymerization modification. Starting from the (7-oxa)norbornene anhydride derivatives, we have developed pathways to cationic …
