Summary:Recently, great attention has been devoted to the graphene because of its unique properties, such as high charge carrier mobility even at a high charge carrier concentration at room temperature, the existence of mass-less Dirac fermions, Quantum Hall effect at room temperature, gas sensing at the single molecule level and gate controlled transport (electron or hole) properties. Gas concentration effect on electrical conductivity of graphene by Green function method has been modeled however sensor analytical modeling needs to be done. In this paper injected carriers by Prostate Specific Antigen (PSA) concentration are simulated and carrier controlling parameters (F, pH) are suggested. Injected carriers from PSA to the graphene surface are monitored and their effect on the capacitance is modeled. Finally comparison with experimental data which illustrates good agreement between them is considered.
