7_20/2011Imaging: Exploring the Formation of Focal Adhesions on Patterned Surfaces Using Super-Resolution Imaging (Small 20/2011)

The cover image illustrates the formation of focal adhesions on fibronectin nanopatterns as revealed by super-resolution imaging. The localization-based super-resolution imaging technique was employed to determine the position and density of vinculin proteins in the focal adhesions. A characteristic distance of 50 nm was found between vinculin molecules in the focal adhesions, which did not depend on the size of the fi bronectin nanopatterns; this distance is crucial for the formation of focal adhesions. In addition, the density of vinculin at the focal adhesions formed on the nanopatterns increased as the pattern size decreased.
