| Summary: | Silver nanoparticles are being given considerable attention because of their interesting properties and
potential applications. One such exploitable use is as the major constituent of conductive inks and pastes used for
printing various electronic components. This paper presents a novel direct-writing process for fabrication of the first
deposited silver nanoparticles (AgNPs) (50-200nm) electrode via a thermal inkjet printer. In this method, AgNPs were
chemically deposited by ejection of ascorbic acid and silver nitrate solutions onto different substrates such as paper
and textile fabrics. Silver deposited patterns were used as electrodes in different electrochemical experiments and their
morphology was also investigated in SEM observations. The highest conductivity of deposited electrodes obtained on
paper as the substrate was found to be around 5.54x105 S/m. Inkjet fabricated electrodes exhibited acceptable
electrochemical behavior in experiments designed for measuring the concentration of hydrogen peroxide as a
fundamental procedure for early determination of glucose. This novel inkjet silver deposition technique is introduced
to be considered as a promising method for ultimate single step fabrication of different electrochemical bio-sensors. |
