Smart writing by electrons: A new technique enables the fabrication of full-coverage polymer brush patterns of variable shape on a nanometer length scale. The key to this technique is electron-beam activation of amino groups, which serve as the nucleation centers for surface-initiated polymerization. The technique untangles chemistry and morphology, and it is possible to monitor only morphology effects on chemically homogeneous surfaces and interfaces.
