Plasmon-enhanced rotational dynamics of anisotropic core-shell polymeric-metallic microparticles
文献摘要：
The development of efficient and cost-effective micromachines is a challenge for applied and fundamental science,given their wide fields of usage.Light is a suitable tool to move small objects in a noncontact way,given its capabilities in exerting forces and torques.However,when complex manipulation is required,micro-objects with proper architecture could play a specific role.Here we report on the rotational dynamics of core-shell particles,with a polymeric nematic core of ellipsoidal shape capped by Au nanoparticles.They undergo a peculiar syn-chronous spinning and orbital motion when irradiated by a simple Gaussian beam,which originates from the coupling of the metallic nanoparticles'optical response and the core anisotropies.The rotation capabilities are strongly enhanced when the trapping wavelength lies in the plasmonic resonance region:indeed,the spin kinetic energy reaches values two orders of magnitude larger than the one of bare microparticles.The proposed strategy brings important insights into optimizing the design of light controlled micro-objects and might benefit appli-cations in microfluidics,microrheology,and micromachining involving rotational dynamics.
