Enantioselective optical trapping and characterization of all dielectric disorder-enabled chiral particles
Guilherme T. Moura, Tanja Schoger, Kainã G. Diniz +9
We trap submicroscopic silica spheres coated with randomly distributed titanium dioxide nanoparticles in optical tweezers with Laguerre-Gaussian modes and observe orbital dynamics…
Probing the chirality of a single microsphere trapped by a focused vortex beam through their orbital period
Kainã Diniz, Tanja Schoger, Arthur L. Fonseca +6
When microspheres are illuminated by tightly focused vortex beams, they can be trapped in a non-equilibrium steady state where they orbit around the optical axis. By using the Mie-…
Precise in situ radius measurement of individual optically trapped microspheres using negative optical torque exerted by focused vortex beams
Kainã Diniz, Tanja Schoger, Guilherme T. Moura +6
We demonstrate a new method for determining the radius of micron-sized particles trapped by a vortex laser beam. The technique is based on measuring the rotation experienced by the…
