Figure 7.
Work of adhesion required to deform Gram-negative bacteria. (a) Shown is the assessment of the cell wall deformation by the maximal uniaxial strain in longitudinal direction (ε22), probed at pillar apex. (b) Shown is the assessment of the outer membrane deformation by maximal areal strain (εA), probed at pillar apex. Bracketed values indicate corresponding dimensionless sinking depth (p/r). Data are for pillar diameter and pattern spacing of 60 and 180 nm, respectively. To see this figure in color, go online.
