In article number 2103409, Young Keun Kim, Heemin Kang, and co‐workers present an adhesive nanohelical nanostructure that is partially affixed to the surface, which can be actively manipulated to wind in any direction. This active winding modulates integrin recruitment onto the adhesive nanostructure at a single cell level to mediate an assembly of adhesion structures that...
Developing materials with the capability of changing their innate features can help to unravel direct interactions between cells and ligand‐displaying features. This study demonstrates the grafting of magnetic nanohelices displaying cell‐adhesive Arg‐Gly‐Asp (RGD) ligand partly to a material surface. These enable nanoscale control of rapid winding (“W”) and unwinding (“UW”) of their nongrafted portion,...
