Abstract:
High-resolution transmission electron microscopy revealed nearly atomically precise images of stepping conformational change and translational motion of single hydrocarbon molecules confined in carbon nanotubes. One or two C12 or C22 alkyl chains were tethered to a carborane end group and then embedded in the nanotubes. Images of the hydrocarbon chains interacting with each other and with a graphitic surface provide information on three-dimensional structures and dynamic molecular interactions that cannot be obtained by other analytical methods.

Protein Dynamics in Living Cells
Fluorescent recovery after photobleaching (FRAP) is a fluorescent-protein-based detection technique used to quantify protein movement rates within the cell. This method exposes a small portion of the cell to an intense laser beam. The laser beam causes permanent photobleaching of the fluorophore-tagged proteins in the exposed region. As the bleached...
