Biomimetic Dynamics of Nanoscale Groove and Ridge Topography for Stem Cell Regulation

Advanced Materials, EarlyView.
Dynamic nanoscale groove‐ridge structures are engineered by flexibly conjugating RGD‐magnetic nanoparticles to nanogroove templates with variable groove widths at the molecular scale. Magnetic control enables cyclic switching between nanoscale groove and ridge states that modulates ligand accessibility of cellular integrins.
