Abstract [en]

In this article, a comprehensive overview of the most recent developments in the field of stripping voltammetryat regular micro-interfaces (both solid–liquid and liquid–liquid interfaces) is presented. Thisreview will report on the most conventional arrays of metallic micro-electrodes but also on the rapidlygrowing field of electrochemistry at arrays of micro-interfaces between two immiscible electrolyte solutions(ITIES). The main fabrication methods, together with some design considerations and diffusionphenomena at such interfaces are discussed. Main applications of micro-interface arrays are presentedincluding heavy metals detection at micro-electrode arrays and detection of organic molecules (aminoacids, vitamins, peptides and drugs) at the ITIES. Stripping analysis at micro-interface arrays is suitablefor the detection of analytes in several real media including water, soil extracts and biological fluids(blood and saliva) with high specificity, sensitivity (detection limits of nM, ppb level) and reliability.Stripping analysis at ITIES and micro-electrode arrays are two complementary approaches that havethe advantages of being cost effective, simple to use and easily adaptable to field measurement.
