Studies on Adsorption of DNA on Functional Ultrathin Films of Cationic Surfactant
Figure 3
AFM image of (a) SAM of ODT on gold deposited quartz crystal, (b) one layer of LB film of DOAB deposited over the SAM of ODT, and (c) DNA adsorbed over DOAB after the QCM measurement. The images were scanned in semicontact mode of the AFM. Left column represents the height images and right column is the corresponding phase image.
