(a) EGFP transfection effciency of a collection of SNPs⊃DNA and RGD-SNPs⊃DNA along with control delivery systems for two αvβ3 high-expressed cells (U87 and scraping-collected 3T3 cells) and two αvβ3 low-expressed cells (MCF7 and 0.25% trypsin-treated 3T3 cells). The representative fluorescence micrographs of 57 ± 11% and 9 ± 4% transfection effciencies observed for (b) 5 mol% RGD-grafted 100 nm RGD-SNPs⊃DNA (100-5%)-treated αvβ3 high-expressed 3T3 cells and (c) 1 mol% RGD-grafted 300 nm RGD-SNPs⊃DNA (300-1%)-treated αvβ3 low-expressed 3T3 cells.
