CV results showed that these PCz thin films have reversible redox behavior in monomer-free electrolyte solution. The resulting thin polymer films were characterized using Fourier transform infrared attenuated total reflectance spectroscopy (FTIR-ATR) and atomic force microscopy (AFM). Results performed at optimum experimental conditions indicate that electrodes show a reversible and stable behavior over sixty eight days of testing for dopamine in 100 A mu mol center dot dm(-3) buffer solution. A detection limit for PCz thin films as low as 0.1 A mu M (3S/N) was obtained for the polycarbazole (PCz) thin films formed using CV. Hence, this novel sensor can be considered as promising sensor for dopamine detection.en10.1007/s12221-009-0046-4info:eu-repo/semantics/closedAccessPoly(carbazole)Carbon fiber microelectrodeCyclic voltammetryDopamineAtomic force microscopeElectrochemical Impedance SpectroscopyThin-FilmsCarbazoleCopolymerPolymersPyrroleThiopheneArticle1014652Q2WOS:0002639773000082-s2.0-62249144309Q2
