Atomic force micrographs of blunt and sticky-ended BTX linear arrays. (a) A mixture of sticky-ended BTX A and B tiles lacking streptavidin labels. One-dimensional linear arrays are visible. (b) A mixture of blunt-ended A and B BTX tiles lacking streptavidin labels. These tiles also produce 1D linear arrays. In neither (a) nor (b) are the hairpins clearly visible. (c) An array like those in (a), but labeled with streptavidin. The regular 40 nm repeat of streptavidin markers is visible. (d) Arrays like those in (b), but labeled with streptavidin. Varied spacings between the streptavidin markers can be seen. Scale bars: (a) and (b), 250 nm; (c) and (d) 100 nm.
