Active Motion of Janus Particle by Self-thermophoresis in Defocused Laser Beam

Hong-Ren Jiang, Natsuhiko Yoshinaga, Masaki Sano

We study self-propulsion of a half-metal coated colloidal particle under laser irradiation. The motion is caused by self-thermophoresis: i.e. absorption of laser at the metal-coate…
