A sweeping success: The surface-initiated, atom-transfer radical polymerization of [2-(methacryloyloxy)ethyl]dimethyl(3-sulfopropyl)ammonium hydroxide (MEDSAH) on silicon and gold surfaces leads to homogeneous and patterned brushes of poly-MEDSAH. The association state of the zwitterionic side-groups is determined (see picture; wettability of thin (left) and thick (right) brushes).
