ABSTRACT:
An ionic polymer is utilized in “recharging” (another layer having a different charge) a condensed polynucleotide complex for purposes of nucleic acid delivery to a cell. The resulting recharged complex can be formed with an appropriate amount of positive or negative charge such that the resulting complex has the desired net charge.
