Three figures showing the principles of droplet movement caused by the Marangoni flow

Caption

The synthetic droplets contain the enzyme urease which catalyzes the breakdown of urea into ammonia, which has a high pH-value. Droplets migrate due to the pH gradient, from low to high, because of the Marangoni effect.
