  • Patent number: 8765926
    Abstract: The present invention pertains to a supramolecular structure based on i-motif tetramers of Cm—X—Cn oligonucleotides, wherein m and n are integers comprised between 2 and 9, and X is a linker such as A, T, G, a modified deoxynucleotide or a diol spacer. These supramolecular structures can be dissociated, when necessary, by a mere pH change. The present invention also relates to methods for obtaining such a supramolecular structure.
