Polyethylene Glycol-Coated Gold Nanoparticles as DNA and Atorvastatin Delivery Systems and Cytotoxicity Evaluation

Figure 6

Electropherogram of pSV-β-Gal and AuNP interaction. In lanes 1 and 2, the shift of different quantities of pDNA can be observed. Lane 3 contained the uncoated 40 nm gold nanoparticles and 400 ng of pDNA; the negative charges in both did not allow the interaction between them. Lanes 4 to 7 contained different quantities of pDNA bind to the PEGylated gold nanoparticles.
