Experimental results show that the self-motion of an oil droplet is confined on an acid-treated glass surface. The transient behavior of oil-droplet motion is also observed with a high-speed video camera. A mathematical model that incorporates the effect of the glass surface charge is built based on the experimental observation of oil-droplet motion. A numerical simulation of this mathematical model reproduced the essential features concerning confinement of oil droplet motion within a certain chemical territory and also its transient behavior. Our results may shed light on physical aspects of reactive spreading and a chemotaxis in living things. © 2005 The American Physical Society., 金沢大学大学院自然科学研究科計算科学, 金沢大学理学部}, pages = {1--8}, title = {Chemosensitive running droplet}, volume = {72}, year = {2005} }
