Artificial chemotaxis

One of the fundamental properties of living organisms is the ability to sense and respond to changes in their environment by movement. If a motile cell senses soluble molecules and follows along a concentration gradient to the source, or if it moves away from a source of undesirable chemicals (e.g. repellent, toxin), it is displaying a directional movement called positive or negative chemotaxis, respectively. This phenomenon is well-known to biologists and intensively studied in living systems. Recently we have shown that decanol droplets in the presence of aqueous solution of sodium decanoate are able to follow the additions of sodium chloride. This kind of artificial chemotaxis has been observed in both narrow channels and topologically complex systems, such as maze.
