FIU Electronic Theses and Dissertations
Complex biological processes occur in the nanoscale (1-100 nm) regime. ‘DNA’ which is just 2 nm in dimension is a fundamental building block of all life. ‘Hemoglobin’, a blood protein that transports oxygen throughout our body is only 5 nm in diameter. Importantly, the structure, composition, and dynamics of these nanoscale entities determine their biological function. A slight alteration in the structure and composition can lead to the malfunction of the protein which is key to various diseases including cancer. Therefore, the single-molecule measurement approach is essential to characterize both the average properties and the rare …

FIU Electronic Theses and Dissertations
Biomolecular interactions, including protein-protein, protein-DNA, and protein-ligand interactions, are of special importance in all biological systems. These interactions may occer during the loading of biomolecules to interfaces, the translocation of biomolecules through transmembrane protein pores, and the movement of biomolecules in a crowded intracellular environment. The molecular interaction of a protein with its binding partners is crucial in fundamental biological processes such as electron transfer, intracellular signal transmission and regulation, neuroprotective mechanisms, and regulation of DNA topology. In this dissertation, a customized surface plasmon resonance (SPR) has been optimized and new theoretical and label free experimental methods with related analytical …
