摘要：

Screen-printed electrodes have been used widely in bioprocesses and are inexpensive, easily mass-produced, reproducible and simple. Moreover, conducting polymers have been deposited across screen-printed carbon tracks to form sensors. Recently we reported on two novel methods for the electrochemical growth of conducting polymer filaments across screen-printed carbon track arrays and showed that a filament sensor was three times more sensitive to ethanol vapour than a broad sensor. In this paper, we report further progress in this avenue of research that includes not only ethanol as analyte but also ozone. (C) 2003 Elsevier B.V. All rights reserved.
