Localized Electrografting of Diazonium Salts in the SECM Environment

Electronic, biology and chemical biology have pushed the scientists to develop new techniques to graft locally organic molecules on surfaces. The objective of the work was to develop a cheap and lithography-free technique by combining Scanning Electrochemical Microscopy (SECM) and electrografting processes in view of tuning locally chemical and physical surface properties on initially homogeneous substrates. The electrografting process was carried out with diazonium salts Plots, lines or more complex 2D-patterns have been “imprinted” on conducting substrates.
