Upper panel Agarose gel retardation study on the formation of nanoparticle/pDNA and PEI/pDNA complexes at various N/P ratios (ranging from 0.5 to 5). Lower panel Comparison of PMMA–PEI nanoparticles and PEI mediated transfection at various N/P ratios in HeLa cells. 2 μg of pGL3-Control plasmid was used for the preparation of each complex, and the luciferase activities were measured 36 h after transfection
