Abstract :
In this paper, Magnetic Resonance Force Microscopy for use in the detection of mold spores is proposed. The proposed sensor uses an array of MEMS cantilevers to detect the chemical composition of a sample. That sample is adhered to the surface below the cantilever using an antifungal antibody. Using MRFM techniques, it is possible to determine the chemical composition of the sample. The sensor discussed in this paper specifically targets Fusarium Graminearum fungus. The results from this work can be expanded on for detection of other spore types. Computer simulations are used to calculate the dipole magnetic force which acts on the cantilever when an RF pulse of a given frequency is applied to the sample.
