Fig. 4From: Dynamic interaction of injected liquid jet with skin layer interfaces revealed by microsecond imaging of optically cleared ex vivo skin tissue modelVariation of (a) contrast and (b) SBR with clearing time in the fluorescence imaging mode. Data series marked by (***) and (*) have p-value \(\le\) 0.001 and p-value \(\le\) 0.05, respectively. c Qualitative visualization of the capillary tubes under fluorescence imaging mode on a normalized scale. Scale bar = 1 mm. Skin tissue surface is marked by the yellow dashed linesBack to article page
