Figure 2.

(a) 10 × 10 μm AFM image of 10plex RT-PCR products (15 amplification cycles) produced using Universal Total Human Reference RNA as a template. (b) First inset shows various PCR amplicons highlighted in white with their associated backbone contour measurements. (c) Second inset shows individual amplicons classified by species. Note that background objects are not identified as amplicons due to their nonlinear shape (∗ and ∗∗) or because they were shorter than the smallest expected amplicon (∗∗∗).
