Fig. 5: Mass sensitivty of the resonator for different vibration modes.

Allan deviation and corresponding lowest buoyant mass detection limit for a the first bending mode, b the second bending mode and c the first torsional mode. The validity line (black-dotted line) is determined by (2.33/ωPLL). The blue-dashed and red-dashed lines represent the Allan deviation that can be achieved theoretically by our system if only thermomechanical noise is present
