Mixed structures resulting from the incorporation of a biological macromolecule, particularly dna, into a liquid-crystal phase of amphiphiles, and vesicles obtained from these structures

Abstract From the Canadian patent

The invention relates to a structured mixed phase that results from the incorporation of a biological macromolecule into a liquid-crystal preferably , lamellar, amphiphile phase characterised in that the proportion of said biological macromolecule in said structured mixed phase is at least 5 wt. % in relation to the amphiphile compounds making up the liquid-crystal amphiphile phase and in that at least one of the two entities constituted by the biological macromolecule and the group of amphiphile compounds has no charge. The biological macromolecules incorporated in the inventive structured mixed phases are preferably chosen from the polynucleotides particularly DNA or , RNA, …
