(a) Gene transfer efficiency of HEK-293 cells mediated by the DNA-doped nanocomposites. The gene transfer efficiency of cells was expressed as the amount of the reporter enzyme β-gal normalized by total protein. Nanocomposites formed on unmodified gold surface (Au), polystyrene surface (PS) and Lipofectamine™ 2000 (Lipo) were used as controls. The mineralization was conducted for 24 h. (b) The correlation of gene transfer efficiency with the intracellular DNA level in HEK-293 cells mediated by the DNA-doped nanocomposites.
