Cavity optomechanics experiments with nanoscale resonators are challenging because of their subwavelengh dimensions, but offer interesting insights into dispersive as well as dissipative coupling and dynamical backaction. We employ a resonator-in-the-middle approach using a fiber-based Fabry-Perot micro cavity as a high finesse and low mode volume probe of the nanoresonator. Systems under investigation include silicon nitride string resonators, carbon nanotubes and atomically thin two dimensional materials.
