Cavity and Doppler cooling of trapped silica nanospheres and microspheres to their motional ground state is described. Characterisation of the levitation of a range of silica spheres from radius 25 nm to 5 µm in both optical and ion traps in vacuum is reported and prospects for realizing cooling in these systems is discussed.
