Abstract

For DNA probe contrasting is proposed a coloured coordination complex of Ag. It consist of the oligomer ethanolamino-formaldehyde chains with brutto-formula NC5H13O4 which are connected by coordination bonds with the metal ion. The numbers of ligand depend on the incubation media, the time of reaction and determine the complex colour– from violet to orange-red. It isn't excluded the branching of the single chain by atom N with the forming of the red coloured complex.
