摘      要：Increasing interest has been drawn to optical manipulation of metal(plasmonic)nanoparticles due to their unique response on electromagnetic radiation,prompting numerous applications in nanofabrication,photonics,sensing,*** familiar point-like laser tweezers rely on the exclusive use of optical confinement forces that allow stable trapping of a single metal nanoparticle in 3 *** all-optical(contactless)confinement and motion control of single and multiple metal nanoparticles is one of the major challenges to be *** article reports and provides guidance on mastering a sophisticated manipulation technique harnessing confinement and propulsion forces,enabling simultaneous all-optical confinement and motion control of nanoparticles along 3 D *** an example,for the first time to our knowledge,programmable transport of gold and silver nanospheres with a radius of 50 and 30 nm,respectively,along 3 D trajectories tailored on demand,is experimentally *** has been achieved by an independent design of both types of optical forces in a single-beam laser trap in the form of a reconfigurable 3 D *** controlled motion of multiple nanoparticles,far away from chamber walls,allows studying induced electrodynamic interactions between them,such as plasmonic coupling,observed in the presented *** independent control of optical confinement and propulsion forces provides enhanced flexibility to manipulate matter with light,paving the way to new applications involving the formation,sorting,delivery,and assembling of nanostructures.
