Design and simulation of nano-mechanical resonator for virus detection

In the present study, nano mechanical resonator is used to detect different viruses. Biosensors have been designed using single walled Boron Nitrite Nanotube (SWBNNT) as a sensing material in terms of nanowire and micro cantilever. Here we have considered two approaches for sensing the biomolecules. First one is to calculate the change in resonance frequency of nanowire and second one is to calculate the bending deformation of micro cantilever in the measurable range. Resonance frequency shift of nanowire with and without virus has been calculated. Mass sensitivities of Boron Nitride nanowires are found to be more with increase in frequency shift.
