- Although centrosomes nucleate and organize microtubules in mitotically-dividing cells, spindles in female reproductive cells (oocytes) form in their absence. In some organisms acentrosomal spindle assembly is mediated by acentriolar microtubule organizing centers (MTOCs) that are thought to functionally replace centrosomes. However, spindle assembly in human oocytes does not require MTOCs;...

- Approximately 80-90% of individuals with Parkinson’s disease (PD) develop motor speech impairments, predominantly in the form of voice dysfunction. It is known that the motor symptoms of PD arise from degeneration of the dopamine producing neurons in the substantia nigra and dysregulation of basal ganglia motor pathways. It is also...

- Description:
- This thesis focuses on the design of hybrid organic materials comprising polymers and small molecules for biodiagnostic and electronic applications. Specifically, the electrochemical and fluorescent signaling properties of terthiophene-functionalized polymers are combined with the enhanced recognition properties of DNA hybrid materials, culminating in the development of a "loaded" probe for...
