Back Cover: A Supramolecular System for the Electrochemically Controlled Release of Cells (Angew. Chem. Int. Ed. 49/2012)
Electrochemically activated cell release by using redox-active supramolecular complexes assembled on microelectrodes is described by P. Jonkheijm et al. in their Communication on page 12233 ff. Host molecule cucurbituril links surface-bound viologen to solution-exposed RGD peptides to form a cell-adhesive surface. Electrochemical reduction results in dissociation of the supramolecular complex, release of the RGD peptides, and detachment of cells from the surfaces.
