Surface Wettability Switched Cell Adhesion and Detachment on Conducting Polymer Nanoarray

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.
