Section:Abstract
Droplets emitting surface-active chemicals exhibit chemotaxis toward low-pH regions. Such droplets are self-propelled and navigate through a complex maze to seek a source of acid placed at one of the maze’s exits. In doing so, the droplets find the shortest path through the maze. Chemotaxis and maze solving are due to an interplay between acid/base chemistry and surface tension effects.

Control of Initiation, Rate, and Routing of Spontaneous Capillary-Driven Flow of Liquid Droplets through Microfluidic Channels on SlipChip
Rebecca R. Pompano, Carol E. Platt, Mikhail A. Karymov, and Rustem F. IsmagilovLangmuir2012 28 (3), 1931-1941Control of Initiation, Rate, and Routing of Spontaneous Capillary-Driven Flow of Liquid Droplets through Microfluidic Channels on SlipChip
Rebecca R. Pompano, Carol E. Platt, Mikhail A. Karymov, and Rustem F. IsmagilovLangmuir2012 28 (3), 1931-1941This Article describes the use of capillary pressure to initiate and control the rate of spontaneous liquid–liquid flow through microfluidic channels. In contrast to flow driven by external pressure, flow driven by capillary pressure is dominated by ...
pH-Sensitive Self-Propelled Motion of Oil Droplets in the Presence of Cationic Surfactants Containing Hydrolyzable Ester Linkages
Taisuke Banno, Rie Kuroha, and Taro ToyotaLangmuir2012 28 (2), 1190-1195pH-Sensitive Self-Propelled Motion of Oil Droplets in the Presence of Cationic Surfactants Containing Hydrolyzable Ester Linkages
Taisuke Banno, Rie Kuroha, and Taro ToyotaLangmuir2012 28 (2), 1190-1195Self-propelled oil droplets in a nonequilibrium system have drawn much attention as both a primitive type of inanimate chemical machinery and a dynamic model of the origin of life. Here, to create the pH-sensitive self-propelled motion of oil droplets, we ...
