Patent ID: 7981638

Claim:
A molecule transfer and delivery system comprising: a carrier molecule having a first single-stranded nucleotide; a target cargo molecule having a second single-stranded nucleotide; a loading zone configured to allow the targeted cargo molecule to be loaded on the carrier molecule by formation of a partial double strand between a segment of the first single-stranded nucleotide and a complementary segment of the second single-stranded nucleotide; and an unloading zone to which a third single-stranded nucleotide is bound, the unloading zone being configured to cause the target cargo molecule to be unloaded from the carrier molecule by formation of a complete double strand between the second single-stranded nucleotide and the third single-stranded nucleotide that is more stable than the partial double-strand formed between the first single-stranded nucleotide and the complementary segment of the second single-stranded nucleotide.
