    "abstract": "Nanomechanical resonators can now be realized that achieve fundamental\nresonance frequencies exceeding 1 GHz, with quality factors (Q) in the range\n1,000 - 100,000. The minuscule active masses of these devices, in conjunction\nwith their high Qs, translate into unprecedented inertial mass sensitivities.\nThis makes them natural candidates for a variety of mass sensing applications.\nHere we evaluate the ultimate mass sensitivity limits for nanomechanical\nresonators operating in vacuo, which are imposed by a number of fundamental\nphysical noise processes. Our analyses indicate that nanomechanical resonators\noffer immense potential for mass sensing - ultimately with resolution at the\nlevel of individual molecules.",
