Disposable electrochemical paper-based devices fully fabricated by screen-printing technique
Abstract This work presents a novel method for the full fabrication of electrochemical paper-based cells by screen-printing technology. Firstly, a mixture of ultraviolet curable inks was used for patterning hydrophobic barriers into chromatography paper. Afterwards three-electrode systems were coupled for electrochemical detection by printing successively carbon and silver/silver chloride inks over the hydrophilic areas. The resulting electrochemical cells were characterized by cyclic voltammetry in different redox systems and used for amperometric detection of ferricyanide. Highlights Hydrophobic barriers are screen-printed into paper with a mixture of UV curable commercial inks. Three-electrode systems are printed over these patterned papers for electrochemical detection. The resulting electrochemical paper-based cells are suitable for electroanalytical use.
