  The rapid development of micro- and nanooscillators in the past decade has
led to the emergence of novel sensors that are opening new frontiers in both
applied and fundamental science. The potential of these novel devices is,
however, strongly limited by their increased sensitivity to external
perturbations. We report a non-invasive optomechanical nano-stabilization
technique and apply the method to stabilize a linear nanomechanical beam at its
ultimate thermodynamic limit at room temperature. The reported ability to
stabilize a mechanical oscillator to the thermodynamic limit can be extended to
a variety of systems and increases the sensitivity range of nanosensors in both
fundamental and applied studies.
