Nanocrystalline cellulose from the sulfuric acid hydrolysis process has been funcionalized with nitrogen based ligands. The class of cyanine dyes was used as a fluorescent tag for DNA detection. The differences in DNA detection by using free cyanine dyes compared to cyanine dyes coordinated to CNC will discussed. By coordinating the cyanine dyes to CNC the aggregation state and thus the dyes fluorescence properties changed. At a narrow ratio of CNC and cyanine dyes these aggregates formed complexes with DNA.
