Crosslinked bioreducible polypropylenimine-cystaminebisacrylamides (PPI-CBAs) were synthesized for gene delivery systems. They formed nano-sized polyplexes with high stability even in reducing condition probably due to the re-crosslinking. PPI-CBAs displayed high transfection efficiency comparable to PEI25k in serum condition. However, cytotoxicity increase
