A family of cationic Pluronic‐based polyrotaxanes (PR + ), threaded with 2‐hydroxypropyl‐β‐cyclodextrin (HPCD), was synthesized for pDNA delivery into multiple cell lines. All PR + formed highly stable, positively charged pDNA complexes that were < 250 nm in diameter. The cellular uptake and pDNA transfection efficiencies of the PR + :pDNA complexes was enhanced relative to the commercial transfection standards L2K and bPEI, while displaying similar or lower toxicity profiles. Charge density and threading efficiency of the PR + agent significantly influenced the colloidal stability and physical properties of the complexes, which impacted their intracellular transfection efficiencies. Taken together, our results suggest that HPCD: Pluronic PR + can be used as potent vectors for pDNA‐based therapeutics.
