Figure 4

Normal peeling forces (90°w.r.t gel/glass interface) are applied at different positions for wide line pattern, i.e. 100 um. The cracks propagate along 2 different directions, respectively. (a1) Peeling force is applied as shown. (a2) cracks propagate along the line patterns. The entrapped cracks propagate inward from the sides. (a3) The resulting FN patterns on gel and FN residues on intermediate glass slides. (b1–b2) cracks propagate orthogonally to the line patterns. (b3) The resulting FN patterns on gel and FN residues on intermediate glass slides.
