We have achieved simultaneous measurement of the mass and particle number of adsorbed particles by vibrating suspended graphene with Joule heat generated by applying electric current, leading to specific detection of viruses. Since it is difficult to distinguish between small amounts of virus adsorption and contaminants, it is essential to improve the discrimination ability by increasing the sensitivity of the particle count measurement. In this study, we fabricated a single graphene resonator with a reduced channel area to improve the sensitivity of particle counting.
