Fibre Optic Readout of Microcantilever Arrays for Fast Microorganism Growth Detection

Figure 4

Resonance frequency response of agarose-functionalised cantilevers. The thin, medium and thick agarose sensors correspond to 1-, 5-, and 10-second incubation times during functionalisation, respectively. The response to humidity changes increases with increasing layer thickness. Frequency noise levels are also seen to increase slightly with increasing layer thickness. Zero point on right hand axis corresponds to 36% RH.
