Abstract
Treatment of diseases on the molecular level by genetic material is limited by effective delivery mechanisms. We focused on the synthesis of a pH-sensitive gene delivery vehicle based on dimethylaminoethyl methacrylate (DMAEMA) with tunable swelling, cross-linking density, and DNA release kinetics within the endosomal pH range. Our strategy, which utilized a single step for DNA encapsulation, enhanced gene transfection efficiency and reduced cytotoxicity relative to polyethyleneimine (PEI) and poly-L-lysine (PLL).
