Abstract
The present paper investigates the vibrational characteristic of fixed free single walled boron nitride nanotube with attached bacterium or virus on free end to explore their suitability as bacterium or virus detector device or biosensor. The continuum solid modeling based finite element method approach has been used to analyze the various modes and resonant frequency shift caused by bacterium or virus on beam tip. The obtained simulation results have been compared with analytical results based on fixed free beam bending model. To be more precise in present analysis, the vibrational characteristic of four types of single walled boron nitride nanotubes of different lengths of same diameter have been considered. The different types of bacterium or virus at the tip of the fixed free single walled boron nitride nanotubes have been analyzed for their resonant frequency variation based analysis. The obtained simulation results have been found in sensible agreement with the analytical results. The obtained simulation results suggest that detection of the bacterium or virus having mass of 2.90 x 10-23 kg can be effectively performed.
