Conducting‐polymer towers have been fabricated by a template‐less method from homogeneous monomer solution using the scanning electrochemical microscope (SECM). The features of the topography feedback mode of the SECM—in which the microelectrode is vibrated laterally (thin arrows in the Figure)—are described and the characterization of polypyrrole towers (illustrated on the front cover) detailed. Uses in biosensors are foreseen.
