Protein immobilization into structured polymer brushes was achieved by AFM lithography. Dense polystyrene brushes with thicknesses larger than 40 nm show protein repellent properties whereas brushes with thicknesses smaller than 20 nm show the expected knownprotein adsorption behavior. Multi tip AFM lithography allows for large surface area patterning.
