Spontaneous motion of a droplet coupled with a chemical wave
Hiroyuki Kitahata, Natsuhiko Yoshinaga, Ken H. Nagai +1
We propose a novel framework for the spontaneous motion of a droplet coupled with internal dynamic patterns generated in a reaction-diffusion system. The spatio-temporal order of t…
Polarity patterns of stress fibers
N. Yoshinaga, J. -F. Joanny, J. Prost +1
Stress fibers are contractile actomyosin bundles commonly observed in the cytoskeleton of metazoan cells. The spatial profile of the polarity of actin filaments inside contractile…
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…
