Abstract

A new approach for the local deposition of sol–gel films on conducting and insulating surfaces using scanning electrochemical microscopy (SECM) via the feedback and direct modes is presented. Patterning is based on enhancing sol–gel condensation by altering the local pH due to water electrolysis as a result of applying negative potentials.
