Engineering smart nanobiointerfaces which can interact with cells as an artificial niche, that can response to the change of external stimuli, remains a great challenge. Herein, it is demonstrated an electrochemical-responsive nanobiointerface, composed of conducting polymer (polypyrrole) nanoarray, enables highly efficient cell adhesion/detachment with desirable viability along with its dynamic hydrophobic/hydrophilic switching.
