TEM and AFM imaging of an individual HIV-1 Gag VLP. (a) TEM image. (b) AFM 3D topography imaging. (c) AFM amplitude and (d) phase image of the fundamental mode. (e) Second amplitude (A2) and (f) phase (Φ2) images of bimodal AFM, corresponding to the dynamics of the first excited eigenmode. (g) First excited eigenmode frequency shift (Δf2) image of AM-FM viscoelastic mapping mode, and the corresponding calculated (h) Young’s modulus image. To see this figure in color, go online.
