INKJET DEPOSITED SILVER NANOPARTICLE ELECTRODES

Silver nanoparticles are being given considerable attention because of their interesting properties andpotential applications. one such exploitable use is as the major constituent of conductive inks and pastes used forprinting various electronic components. this paper presents a novel direct-writing process for fabrication of the firstdeposited silver nanoparticles (agnps) (50-200nm) electrode via a thermal inkjet printer. in this method, agnps werechemically deposited by ejection of ascorbic acid and silver nitrate solutions onto different substrates such as paperand textile fabrics. silver deposited patterns were used as electrodes in different electrochemical experiments and theirmorphology was also investigated in sem observations. the highest conductivity of deposited electrodes obtained onpaper as the substrate was found to be around 5.54x105 s/m. inkjet fabricated electrodes exhibited acceptableelectrochemical behavior in experiments designed for measuring the concentration of hydrogen peroxide as afundamental procedure for early determination of glucose. this novel inkjet silver deposition technique is introducedto be considered as a promising method for ultimate single step fabrication of different electrochemical bio-sensors.
