Abstract

Light-matter interaction in the context of optical trapping forms the fundamental basis for manipulating objects, enabling a plethora of exciting discoveries in many aspects of science and applications. To date, optical trapping has been explored exclusively on the interactions between electric field component of light and matter. Here we demonstrate the first magnetic optical trap in manipulating nano-objects in space. The potential created purely from magnetic component of light can selectively trap nanoparticles based on the optical magnetic susceptibility. Our work presents a new degree of freedom for studying fundamental light-matter interactions and nano-trapping and manipulation technologies.
