Poly(ethylene glycol) micropillars with gold nanopatterns on top are functionalized with two integrin selective ligands. This platform is a powerful new tool to determine the specific contribution of traction forces involved in cell adhesion mediated by α5β1- and αvβ3-integrins. Cells adherent via α5β1-integrins have a tendency to exert higher maximum forces than cells adhering via αvβ3-integrins.
