The Marcus group is interested in the dynamics of complex systems, including the structure-function of bio-molecular species in the cytoplasm of living cells. To study intracellular processes, we have developed novel fluorescence-based optical techniques to probe center-of-mass motions and internal structural changes of fluorescently labeled organelles, proteins and nucleic acids in their native environment. Fourier imaging correlation spectroscopy (FICS) is a low-signal imaging method designed to probe organelle transport, in addition to macromolecular conformational transition pathways (1). Fluorescence-detected two-dimensional coherence spectroscopy is an important method to study the details of local macromolecular conformation by detecting exciton coupling between chromophore labeled sites (2).
