This paper describes a facile method for the preparation of photoactivatable substrates with tuned surface density of an extracellular matrix peptide to resolve the impacts of biochemical and mechanical cues on collective cell migration. The controllability of surface ligand density was validated by cell adhesion and migration tests, complemented with fluorescence observation of an alternative ligand. Depending on the surface ligand density, HeLa cells either kept or lost collective characteristics. The present materials will be useful to address mechanobiology of collective cell migration.
