Abstract

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.

Abstract

The redox behavior for bulk and nano silver nitrate (NSN) were studied by cyclic voltammetry technique in absence and presence of cefdinir antibiotic (CFD) using glassy carbon electrode (GCE) in 0.1 M KNO3 as supporting electrolyte at two different temperatures. Scan rates were studied for the redox reactions of bulk and nano silver nitrate (NSN) in absence and presence of cefdinir antibiotic (CFD) and mechanism of the electrode reactions were discussed. The stability constant of complexation and thermodynamic parameters for a system were evaluated
