title: Molecular motion and association on the cell surface.
abstract: The size, shape, flexibility and topological relationships of proteins and lipids on cell surfaces and in artificial membranes have been studied by: (1) rotational and translation diffusion using time-resolved spectroscopy of singlet and triplet probes, and (2) fluorescence energy transfer in a flow system.
