Abstract
To the best of our knowledge, to date there is no report for the synthesis of silver nanoparticles capped with oleylamine (AgNPs/OLA) and then use of NPs in the preparation of paper based conductive track for electroanalytical application. The synthesized OLA capped AgNPs was characterized with TEM, UV-visible, EDX, FTIR and TGA to know the size, composition and surface modification of NPs. The best electrical conductivity of printed electronic (0.11x 105 S cm-1) was obtained by applying a 10% AgNPs nano-ink solution on photo paper while keeping sintering temperature at 150oC for 60 min of sintering time. A conductive nano-ink was used to prepare electrodes (counter, reference and working) on photo paper and utilized in cyclic voltammetry (CV) measurement. In addition, we demonstrated the lighting of LED when conductive track was connected to a 1.5 V battery. The advantages of this paper-based flexible electrodes are user-friendly, cost effective and multiple analyses (> 50 times) in CV compared to other printed electrodes.
