Masters Theses & Specialist Projects
Nanotechnology has become the most advanced type of drug delivery system within the last decade. This advancement shifted the focus on small carriers to increase the efficiency of the drugs. Among these, gold nanoparticles (GNPs) were found to have profound biomedical applications. In current research, kanamycin embedded GNPs were prepared in a single step, single phase, and bio-friendly (green synthesis) procedure. The synthesized Kanamycin-GNPs (Kan-GNPs) were spherical in shape and had a size range of 15 ± 3 nm. The chosen kanamycin is an aminoglycosidic antibiotic that is isolated from Streptomyces kanamyceticus. These special antibiotic GNPs are further characterized using …

The aims were to determine the biodistribution, translocation, and persistence of nanoceria in the brain and selected peripheral organs. Nanoceria is being studied as an anti-oxidant therapeutic. Five, 15, 30, or 55 nm ceria was iv infused into rats which were terminated 1, 20, or 720 h later. Cerium was determined in blood, brain, liver, and spleen. Liver and spleen contained a large percentage of the dose, from which there was no significant clearance over 720 h, associated with adverse changes. Very little nanoceria entered brain parenchyma. The results suggest brain delivery of nanoceria will be a challenge.
