Abstract
Purpose - This paper presents a sophisticated methodology for inkjet printing of silver nanoparticles (AgNPs) in the range of 80-200 nm on different flexible substrate. AgNPs was chemically deposited by ejection of silver nitrate and ascorbic acid solutions onto different substrates such as paper and textile fabrics. The fabricated pattern was used to employ as electrode for electrochemical sensors. Design/methodology/approach - The morphology of deposited AgNPs was characterized by means of scanning electron microscopy. Moreover, conductivity and electrochemical behavior were identified respectively using four probe and cyclic voltammetry techniques. Acquired image shows a well defined shape and size for deposited silver nanoparticle. Findings - The conductivity of the paper substrate after printing process reached to 5.54×105 S/m. This printed electrode shows a sharp electrochemical response for early determination of glucose. The proposed electrode provides a new alternative to develop electrochemical sensors using silver nanoparticles chemically deposited on paper and textile fabric surface.Originality/value - current investigation conducted based on an original research work to explore and develope flexible sensor using silver nanoparticles
