1. A three-dimensional nanocage comprising:
a protein covalently linked to a polynucleotide handle, wherein the protein is a homotrimer;
wherein the polynucleotide handle is covalently linked to a solvent exposed cysteine by a disulfide linkage or
wherein the polynucleotide handle is covalently linked to a surface 4-azidophenylalanine residue; and
wherein the polynucleotide handle is at least 15 base pairs long; and
a DNA assembly comprising a polynucleotide arm complementary to the polynucleotide handle linked to the protein, wherein the polynucleotide handle and the polynucleotide arm form a double-stranded complex linked to the protein to the DNA assembly; and
wherein the DNA assembly comprises 4 oligonucleotides.
