(A) Tapping mode AFM height image of a glass surface patterned with channels; the full z-range of the image is 1 μm. (B) Tapping mode AFM height image of single collagen fibrils on a glass surface at ambient conditions; the full z-range of the image is 250 nm. (C) Tapping mode AFM height image of single collagen fibrils on a glass surface in PBS buffer; the full z-range of the image is 225 nm. (D) SEM image of a single collagen fibril spanning multiple channels. The width of the channel is 3.0 ± 0.2 μm.
