Desired numbers of proteins can be positioned on surfaces by using dip‐pen nanolithography (DPN). Ferritin nanoarrays are fabricated by direct‐writing nanodroplets of a ferritin solution on TEM surfaces. After the contact‐angle value of these droplets is determined, the concentration of the inking protein solution and the diameter of the dot‐like feature can be modulated to position a single ferritin particle on a surface (see figure).
