Graphene superior and unique properties make it a suitable material for biosensor. In this work, graphene interaction with yeast cell is investigated for development of graphenebased cell counter. The fabricated graphene channel was characterized by means of two-terminal and solution-gated three-terminal measurement setup. The correlation between graphene channel resistance and cell concentration was confirmed. The yeast cell was found to give n-type doping which modulate the conductivity of graphene channel.
