Abstract
The present disclosure describes a nanoparticle comprising a three dimensional DNA nanocage and a payload biological macromolecule, and methods of assembly thereof.
Claims19
A nanocage comprising;
- a three dimensional body comprising a plurality of structural members comprising M13 viral DNA, wherein internal surfaces of the plurality of structural members form an inner cavity, wherein architectural arrangement of the structural members in the three dimensional body forms an arrangement selected from the group consisting of a honeycomb lattice, a single-walled square lattice, and a double-walled square lattice.
A nanoparticle comprising:
- a nanocage comprising a plurality of structural members comprising DNA in a three-dimensional lattice, wherein internal surfaces of the plurality of structural members form an inner cavity;
- and
- one or more payload molecules bound to internal surfaces of the inner cavity, wherein the one or more payload molecules comprise enzymes, nucleic acids, polypeptides, antibodies, phospholipids, or any combination thereof.
A method of making a nanoparticle comprising, the method comprising;
- trapping a payload macromolecule in an open half cage comprising M13 viral DNA;
- and
- assembling two of said half cages into a closed nanocage having an inner cavity and nanopores;
- wherein the inner cavity comprises the payload macromolecule.
