| Abstract: | The interaction of rhodamine 6G with DNA was studied by the methods of spectrophotometry and scanning probe microscopy. It was ascertained that rhodamine 6G interacts with the DNA macromolecules by cooperative binding to the exterior surface of the polymeric chain. As a result, organic nanostructures form on the surface of the polymers. The number of dye molecules in the nanostructures is estimated. The distribution of these structures along the double helix of DNA and their merging into larger conglomerates is studied. |
