The structure and behavior of a variety of macromolecules and macromolecular systems (proteins, nucleic acids, ribosomes, phospholipid vesicles) have been studied by several techniques. For example, processes related to initiation of protein synthesis were studied by stopped-flow or pressure-jump light-scattering or fluorescence, as well as by more "classical" techniques of molecular biology. The behavior of ribosomes as polyelectrolytes is a continuing interest. The mechanism of cation-induced fusion of phospholipid vesicles--models for the behavior of biological membranes--was probed by stopped-flow fluorescence and light-scattering, while the nature of the vesicle surfaces was investigated by 31P NMR and fluorescence lifetime studies of the interaction with lanthanide cations. NMR has been used over the years to explore problems in protein and nucleic acid behavior. Currently, the emphasis is on magnetic resonance imaging using laser-polarized 129Xe.
