Manipulation of Janus particles is challenging and has limited precision. Here, the authors propose manipulation of Janus particles by optical forces in the evanescent field of an optical nanofiber, and demonstrate that they exhibit strong transverse localization on the nanofiber and much faster propulsion compared to all-dielectric particles of the same size.
