Figure 8

CLSM images of the spatial distribution of E. coli (green fluorescence) on the surface of the developed tri-phasic 3D viscoelastic models. Images were taken at different stages of growth, namely 3 h (lag phase), 5 h (mid-exponential phase) and 7 h (late-exponential phase) of incubation at 37 °C. The fat phase is stained with NileRed (red fluorescence).
