Electronic Theses and Dissertations
Fluorescence microscopy is popular for its noninvasive properties and its use in imaging multiple species, simultaneously. Furthermore, superresolution fluorescence microscopy (SRFLM) utilizes photoswitchable proteins to improve the lateral resolution of conventional fluorescence microscopy by an order of magnitude. There is little work conducted on the study of excitation laser polarizations and their effect on the number of localizations as well as the brightness of molecules. This thesis attempts to study the effect of excitation wavelength polarization on the number of localizations and the brightness of molecules by comparing two orientations of circularly-polarized, excitation lasers. The first type of orientation involves …
