AFM images. (a) AFM images of the DNA molecules that were stretched and immobilized on the N2 plasma-treated polymer film synthesized with 30 W of RF power. (b) The scan profile along the white line of the image (a). (c) AFM image of AuNWs formed along the stretched DNA molecules on the N2 plasma-treated polymer film that was synthesized with 30 W of RF power. (d) The scan profile along the white line of image (c). (e, f) AFM images showing the dependence of DNA stretch and alignment on NH2-functionalized polymer films that were synthesized (e) at 20 W power and (f) at 40 W power, respectively, and then treated with DBD at a RF power of 150 W for 60 s.
