The selective adsorption of the cage protein ferritin onto self-assembled diblock copolymer surfaces is reported. When desired, the adsorption is triggered in situ by changing the potential. Upon this potential change, the minority block, consisting of amorphous polyferrocenylsilane, becomes positively charged. Electrostatic forces are then responsible for the local adsorption of the globally negatively charged ferritin molecules.
