Abstract

The principle of mass detection using nano biosensors is based on the fact that the resonant frequency is very much sensitive to the mass of the bio-molecule, as with mass changes stiffness varies. The change of the attached mass on the CNT causes a shift to the resonant frequency. The key issue of mass detection is in quantifying the shift in the resonant frequency due to the mass of the attached molecule.This study, explores the vibration responses of the cantilever single and double-walled carbon nanotube with various attached microbes on the tip with an aim of developing a sensor. The biological objects studied include Alanine with Amino terminal residue, Deoxyadeonosine with free residue, Coronaviridae, Bartonella bacilliformis etc.. This sensor will be utilized to facilitate the identification of bacteria or virus that may be attached to CNT.
