3D AFM topography images with corresponding 1D profiles through dashed lines as shown.
A) 460 μm sapphire c-cut slide. B) Capture coating on sapphire slide. C) Influenza A H3N2 virus cluster immobilized in capture coating on sapphire slide. The tendrils of the capture coating bPEG2kSA receptor tethers are clearly seen. D) A 2D example image of one of many single virions (this one Influenza A H3N2) immobilized in capture coating. 2DFFT analysis for all four AFM scans shown in S2 Fig.
