NEMS RESONATOR FOR DETECTION OF CHEMICAL WARFARE AGENTS BASED ON SINGLE LAYER GRAPHENE SHEET

In this paper, the idea is to theoretically investigate the possibility of utilizing the single layer graphene sheet (SLGS) for detection of chemical warfare agents (CWA). Based on non-local plate theory the frequency equations were obtained for simply supported SLGS with the attached molecule of arbitrary mass at the center of the SLGS plate. The absolute frequency shift method is used in order to detect specific CWA molecule. This method is based on the difference of resonant frequencies of SLGS with and without attached nanoparticle. Results showed that SLGS could be utilized as a sensing element of nanoelectromechanical (NEMS) resonator for detection of CWA.
