Fibre Optic Readout of Microcantilever Arrays for Fast Microorganism Growth Detection

Figure 6

Optical microscope images of the front and backside of two A. niger coated cantilevers. Figure 6 (A and B) show the front and backsides of cantilevers which correspond to the black and red curves from Figure 5, respectively. Figure C shows an SEM image of mycelium on the surface of a cantilever. Mycelium thicknesses (~2 μm) are of the same order of magnitude when compared to the cantilever thickness (7 μm). The growth of mycelium proceeds at a rate of ~9 μm/h along the length of cantilevers.
