We suggest a novel approach in all-optical trapping employinga photophoretic force for manipulation of absorbing particles in open air.We demonstrate experimentally the robust three-dimensional guiding, overthe distances of a few millimeters, of agglomerates of carbon nanoparticleswith the size spanned from 100 nm to 10μm, as well as their accelerationup to velocities of 1 cm/sec. We achieve stable positioning and guiding ofparticles as well as simultaneous trapping of a large number of particles in adual beam optical trap created by two counter-propagating and co-rotatingoptical vortex beams.
