摘要	Poly-aniline (PAn) film can be oxidized by contacting oxygen in an electron-transfer reaction and its redox state, for instance the open circuit potential and the dielectric constant, is quantitatively related to oxygen concentration. This feature may contribute to an improved application of dissolved oxygen (DO) detection with the combined optical and electrochemical sensor. In this paper, PAn is used as a sensing surface to detect DO by the combination sensor composed of electrochemistry and total internal reflection imaging ellipsometry (EC-TIRIE). Results demonstrate that both optical and electrical signals show a logarithmic correlation with DO concentration (0-20ppm). Compared with the results obtained only with the gold surface, both the optical and electrical signals of the EC-TIRIE sensor for DO detection are amplified with the PAn modified gold surface.
