Nanoscale Topography: Aptamer‐Mediated Efficient Capture and Release of T Lymphocytes on Nanostructured Surfaces (Adv. Mater. 38/2011)

Easy capture and easy release! The cover illustrates a nanostructured platform that combines silicon nanowire arrays and targeted DNA aptamers, realizing significant capture and efficient release of T lymphocytes. This method of capture and release provides an artful strategy to fulfill the demands of cell isolation and diagnostics, as reported by Dong Han, Shutao Wang, and co-workers on page 4376.
