DNA Nanoarrays for RNA Detection (image) Arizona State University Caption On the left is an AFM image of DNA nanoarrays bound to their RNA targets at 1500nm x 1500nm scale. The zoom-in images (150nm x 150nm scale) on the right clearly show the barcode (white dots) that identifies the nanoarray and the RNA hybridization signal on the DNA nanoarray ( white bar).
