Abstract:	Alkanethiols spontaneously assembles from solution or vapour on oxide free metal surfaces resulting in a close-packed molecular stuctures with a high degree of orientation and molecular order. In this study, inkjet printing technique is used to immobilize monolayers of alkanethiols on gold electrodes. The quality of the inkjetted monolayers are analyzed by electrochemical methods, i.e. cyclic voltammetry and electrochemical impedance spectroscopy, and by Polarization Modulation Infrared Reflection-Absorption Spectroscopy (PM-IRRAS) which show a similar molecular quality to those produced by immersion technique, the standard technique. The kinetic and mass transfer behaviours of micro-scale structures of inkjetted monolayers, e.g. bands and dots array electrodes, are explored by electrochemical methods. The microscale inkjetted structures of monolayers are of interest in the fields of microelectronic devices (e.g. chemical and biosensors) and optoelectronic devices. Taking benefits from multichannel existing in the printhead, mixtures of SAMs are demonstrated. Mixing of monolayers differing in functional groups provides a model surface to study interface phenomena at molecular level such as ion permeation, selective chemical binding, and electron transfer kinetic.
