Polyaniline Sulfonate/Cytochrome c Multilayer Electrodes: Polyelectrolytes Properties and Assembly Characteristics

Popis výsledku v původním jazyce

Among the variety of different polyelectrolytes, sulfonated polyaniline (PASA) is found to be suitable for the construction of electroactive cyt c-containing multilayers. On the surface of gold electrodes subsequently coated with up to 16 alternating layers of cyt c and PASA the immobilized protein is fully electroactive, retains its native structure and can be successfully applied as a sensor for superoxide [1]. Here we present a study of the polyelectrolyte influence on the multilayer formation and redox properties of the assemblies formed. Two different sulfonated polyanilines (PASA1 [2] and PASA2 [3]) have been chemically synthesized, the assembly build-up has been investigated by Quartz Crystal Microbalance (QCM), and characterization of these systems on electrodes has been performed by Cyclic Voltammetry (CV). The chemically synthesized PASA versions differ in the grade of sulfonation, chain length, overall charge and the presence of an additional methoxy group on the aniline rin
