SHEAR FLOW SELF-ASSEMBLED GOLD NANOPARTICLE FILM FOR CHEMIRESISTOR SENSOR APPLICATIONS

摘要

We report here a new technique using shear flows, with or without electric field enhancement to self-assemble gold nanoparticle film for vapor sensing application. The described approach to prepare nanoparticle thin film is simpler and faster than conventional layer-by-layer deposition methods[1-2]. It is shown that our self-assembled chemiresistors are adequate for organic vapor sensing. The effect of electric field on self-assembly efficiency was as well studied in this work.
