title: The effect of Mie resonances on trapping in optical tweezers: comment.
abstract: Recently, Stilgoe, et al., [Opt. Express 16, 15039 (2008)] reported calculations of the force on an optically trapped sphere performed using the "optical tweezers toolbox". This software suffers from numerical inaccuracies that lead to qualitative errors in the state diagram for stable trapping, particularly for spheres smaller than the wavelength of light.
