A direct‐writing technique that allows the fabrication of 3D chemically active nanostructures by combining low‐ pressure plasma polymerization with an electron‐beam process is reported. The figure shows functional nanopillars consisting of acrylic acid (carboxylic acid moieties) on a protein‐repellent layer of poly(ethylene glycol). The versatility of the structuring process makes it a promising tool for probing biological systems at the nanoscale.
