Spatial Modulation of Biomolecules Immobilization by Fabrication of Hierarchically Structured PEG-Derived Brush Micropatterns: An Versatile Cellular Microarray Platform

•A hierarchical polymer brushes micropatterned surface was fabricated.•Biomolecules were arrayed on the polymer brushes micropatterned surface.•The microarray with variant density of biomolecules was achieved.•The cell adhesion was evaluated on the biomolecules microarray.•Cell attachment and biomolecules density strongly correlated.
