Mass detection of molecules using single layer graphene sheet is investigated in the present paper. A nanoelectromechanical system resonator device is proposed which is modeled as single layer graphene coupled to electronic transport through such device via two metallic leads. The conductance of such device is deduced by solving eigenvalue differential equation. The influence of both photon energy of an induced ac-field and magnetic field are taken into consideration. The present results show that both the resonant frequency shift and the quality factor are very sensitive to the mass of certain molecule. Also, the photon energy of the induced ac-field enhances the sensitivity of these parameters. The present research is very important for detecting the mass of both chemical molecules and bio-molecules. This can be achieved experimentally by measuring the quantum conductance of the present device, which is related to the resonant frequency shift and the quality factor.
