Construction of supramolecular assemblies and self-organized structures using oligo-DNAs.
To obtain fundamental theories for construction of self-organized structures using oligonucleotides, we constructed multiple aggregates with half-sliding oligo-DNAs. We used several types of half-sliding oligo-DNAs with different stability and number of residues. The formation of multiple aggregates by the oligo-DNAs was confirmed by size exclusion chromatography (SEC). The shape of the aggregates was investigated by atomic force microscope (AFM), and linear structures of multiple aggregates of half-sliding oligo-DNAs were observed.
