dcterms:description
Chemotaxis is defined as an oriented movement along a chemical gradient. Biological chemataxis is crucial for any living organism, because it represents its ability to locate sources of nutrition and to move towards them. Many non-biological objects have also exhibited signs of chemotactic behaviour in various environments, most of them are being researched currently. The common nominator of these systems is a transfer of chemical into mechanical energy, induced by a concentration gradient of another added substance. Some objects have been shown to respond to local temperature changes in their surroundings with chemotactic movement. However, the mechanisms of this oriented movement vary with each system and many are still unexplored. In our present case, we study a system, where decanol droplets move on a glass substrate, which is covered by a thin layer of sodium decanoate. The droplets exhibit the ability to move towards additions of NaCl, we are observing characteristics of this oriented movement and trying to determine, which forces are primary responsible for this phenomena. One of the future applications of controlled non-biological chemotaxis lies in the possibility to use artificial objects to transport drugs in the organism or to clean otherwise inaccessible internal surfaces of machines.
