Figure 3: AFM images of AM-DNA origami rectangles in the absence of protein.
From: A DNA aptamer recognising a malaria protein biomarker can function as part of a DNA origami assembly
(a) Two DNA origami rectangles are visible with a column of discrete raised areas corresponding to the position of aptamers. Paths used for height profile measurements lie between the pink (“B”) and blue (“A”) arrowheads. (b) Height profile plot taken from the height profiles marked in (a). Peaks corresponding to the position of the aptamer-modified strands are clearly visible. (c) A higher magnification image analyzed in the same way as (a) and showing another DNA origami rectangle with four clear aptamer peaks. (d) Height profile plot taken from the height profiles marked in (c).
