Adsorption and release of DNA complexes on two-dimensional PLG disks and cellular transfection. Fluorescence photomicrograph of immobilized PEI/DNA complexes (N/P = 9, 24 h deposition) on (a) untreated PLG or (b) serum-coated PLG. The scale bar indicates 50 µm. X-gal staining of transfected cells (HEK293T) by immobilized complexes (N/P = 9, 24 h deposition) on noncoated (c), and FBS-coated PLG disks (d).
