Reversible photo-switching in a cell-sized vesicle
Tsutomu Hamada, Yuko T. Sato, Takeshi Nagasaki +1
A photosensitive amphiphilic molecule can switch the shape of an assembled vesicle as determined by microscopic observation. Photo-isomerization induces a change in membrane fluctu…
Chemo-Sensitive Running Droplet
Yutaka Sumino, Masaharu Nagayama, Hiroyuki Kitahata +4
Chemical control of the spontaneous motion of a reactive oil droplet moving on a glass substrate under an aqueous phase is reported. Experimental results show that the self-motion…
Dynamics of micrometer-scale phase separation in a polymer mixture upon laser irradiation
Hirofumi Toyama, Hiroyuki Kitahata, Kenichi Yoshikawa
Ten m -sized droplets in an aqueous-two-phase system (water/ polyethylene-glycol (PEG)/ dextran) dissapear upon irradiation with a focused YAG laser. The interface of the dextra…
Mode Selection in the Spontaneous Motion of an Alcohol Droplet
Ken Nagai, Yutaka Sumino, Hiroyuki Kitahata +1
An alcohol (pentanol) droplet exhibits spontaneous agitation on an aqueous solution, driven by a solutal Marangoni effect. We found that the droplet's mode of motion is controlled…
