Dynamics of Chemotactic Droplets in Salt Concentration Gradients
The chemotactic movement of decanol
droplets in aqueous solutions
of sodium decanoate in response to concentration gradients of NaCl
has been investigated. Key parameters of the chemotactic response,
namely the induction time and the migration velocity, have been evaluated
as a function of the sodium decanoate concentration and the NaCl concentration
gradient. The ability of the decanol droplets to migrate in concentration
gradients has been demonstrated not only in a linear chemotactic assay
but also in a topologically complex environment. Additionally, the
ability to reverse the direction of movement repeatedly, to carry
and release a chemically reactive cargo, to select a stronger concentration
gradient from two options, and to initiate chemotaxis by an external
temperature stimulus have been demonstrated
