ZnO nanostructure-modified QCM for dynamic monitoring of cell adhesion and proliferation

► ZnO nanostructures are grown directly on a standard QCM sensor. ► ZnO nanostructures enhance QCM viscoelastic sensitivity. ► Optimal ZnO nanostructure surface morphology was determined for cell adhesion. ► ZnO nanostructure-modified QCM was used for dynamic cell growth monitoring.
