摘要：
Disclosed is a polymer composite (polyplex) that contains nucleic acid, a cationic polymer, and an anionic polymer. The anionic polymer covers the surface of the composite comprising the cationic polymer and nucleic acid, has a negative charge at neutral pH, and can change so as to have a positive charge at mildly acidic pH.
