Figure 1. Deformation of Virus Cross-Section by Adhesion to Substrate.

Figure 1

(a,b) Schemes of a TMV cross-section and its dimensions in solution (a) and immobilized on a hydrophilic oxidized silicon substrate (b) indicating the mechanical deformation of TMV due to strong adhesion via hydrogen bonding (obtained from pdb structure 3J06 manipulated with PyMol, the PyMOL Molecular Graphics System, Version 1.7.4 Schrödinger, LLC). The negatively charged RNA, which is incorporated in the TMV structure, is indicated in yellow. (c,d) Confirmation of the height decrease due to adhesion via AFM height image (c) and the corresponding height profile (d) revealing a height around 14 nm. The scale bar is 400 nm.
