Polymer chain dynamics in solution probed with a fluorescence blob model
Article Abstract:
The new fluorescence tool coined the fluorescence blob model (FBM) that characterizes the chain dynamics of polymers in solution and is employed to analyze the fluorescence decays of polymers randomly labeled with pyrene, is described. The FBM provides information about polymer chain dynamics by establishing a relationship between number of monomers making up a blob, and the lifetime of pyrene used as an internal clock.

Elucidation of residue-level structure and dynamics of polypeptides via isotope-edited infrared spectroscopy
Article Abstract:
Infrared spectroscopy is a powerful tool for analyzing the structure of proteins and peptides. Site-specific structural information can be obtained by sequential, systematic labeling of the backbone and this method of isotope-edited infrared spectroscopy is a tool for obtaining medium-resolution information about the backbone conformation and dynamics.

Solid-state NMR studies of the structure, dynamics, and assembly of beta-sheet membrane peptides and alpha-helical membrane proteins with antibiotic activities
Article Abstract:
The NMR methods used to determine the conformation, orientation, depth of insertion, oligomerization, mobility and lipid interaction of membrane peptides and proteins are reviewed. These studies highlight how the peptides disrupt lipid membrane and provide fundamental insights into the folding of beta-sheet and alpha-helical membrane proteins.
