The compressive and adhesive mechanical properties of self-assembled polymer brushes were investigated using DNA-based modules. The effects of surface anchor density, association strength, and monomer flexibility on the properties were also investigated. Reversible polymer brush properties were examined using atomic force microscopy. It was observed that the effective polymer brush height and resulting adhesive interactions were strongly dependent on surface anchor density and the thermodynamics, concentration, and conformational flexibility of the monomer.
