    Fluorescence microscopy is one of the most widely used tools in cell biology due its intrinsically high detection sensitivity coupled with the ability to genetically label proteins and other cellular structures with fluorescent tags. However, the resolution of fluorescence microscopy has historically been limited to about 200 nm laterally and 800 nm axially because of the diffraction limit of visible light. In the past five years, imaging below the diffraction limit ("super-resolution imaging") by localizing single fluorophores, one at a time (1-3), has opened a wide a variety of new biological systems for study. This Dissertation is a collection of both techniques for two and three dimensional super-resolution imaging as well as applications in bacterial and yeast imaging. References 1.
