Motivated by recent experiments [1] demonstrating optical manipulation of thin silicon nanorods, we investigate the interaction between dielectric needles or discs and the laser field of a high finesse cavity. We show that such anisotropic nanoparticles can be captured from free flight, at velocities much higher than those required to trap dielectric spheres, and that ro-translational cavity cooling should be achievable. We discuss potential applications of these systems for high mass quantum interference experiments as well as for ro-translational cavity optomechanics.
