A dynamic surface can "turn on" the migration of adherent cells. This dynamic property is based on a self-assembled monolayer that presents hydroquinone groups. Electrochemical oxidation converts the hydroquinone into the corresponding benzoquinone, which then undergoes a Diels-Alder reaction with a conjugate of cyclopentadiene and a peptide ligand. This in situ modification of the substrate gives a surface that promotes cell migration (see scheme).
