Abstract: | Electroconductive interpolymer polyaniline complexes are synthesized on the DNA matrix, using the method of oxidative polymerization
of aniline with two different biocatalyzers: horseradish root peroxidase and micropiroxidase-11 biomimetic. The spectral characteristics
and morphology of the acquired biocomposites have been studied. The stereospecificity of the acquired samples of interpolymer
complexes is shown, depending on the biocatalyzers used. The results acquired indicate the important role of a biocatalyzer
in the formation of the twist direction of an electroconductive polymer spiral on the DNA matrix; i.e., the optical activity
of the polymer samples acquired is apparently associated with the biocatalyzer properties. |
