Particle Image Velocimetry Applications of Fluorescent Dye-Doped Particles
… in a flow or a gas-liquid interface. The use of fluorescent light from dye-doped particles has been demonstrated in water applications, but reproducing the technique in an airflow is more difficult due to particle size constraints and safety concerns. The following thesis is formatted in a hybrid …

Measuring and Comparing the Diffusion Rate of Fluorescent-Lipophilic-Neurotracing Probes in Murine-Peripheral-Nerve Preparations
Lipophilic-fluorescent dyes are used as probes to study the neural pathways that wire the brain. Since these dyes are able to define neuroanatomic connections through all stages of normal and mutant development, they are currently the most comprehensive method for neurotracing. In order to …

Role of aromatic pi-stacking on the aggregation of human islet amyloid polypeptide (hIAPP)
… against differently charged lipids, using a fluorescent dye leakage assay. Both modified hIAPP 1-19 sequences were found to be less active when compared to the original hIAPP 1-19 sequence. This might be due to lack of aromatic pi-stacking interactions at the 15th position or due to …
