â¢Hydrophobic barriers are screen-printed into paper with a mixture of UV curable commercial inks.â¢Three-electrode systems are printed over these patterned papers for electrochemical detection.â¢The resulting electrochemical paper-based cells are suitable for electroanalytical use.
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.
