摘要：

介绍了一种基于电泳力的全光捕获和操纵吸收性气溶胶粒子的新方法。我们实验证明，在露天，强大的三维引导的碳纳米颗粒的团聚体的大小跨越两个数量级，从100纳米到10微米，在几毫米的距离，以及他们的加速度高达1厘米/秒的速度和大量的粒子的同时捕获。

英文摘要：

We introduce a novel approach for all-optical trapping and manipulation of absorbing aerosol particles based on a photophoretic force. We demonstrate experimentally, in open air, the robust three-dimensional guiding of agglomerates of carbon nanoparticles with the size spanned for two orders of magnitude, from 100 nanometers to 10 microns, over the distances of a few millimeters, as well as their acceleration up to velocities of 1 cm/s and simultaneous trapping of a large number of particles.
