Tactic motion in nature is one of the key properties of a living organism. Similar behaviour can be observed in inanimate systems at the liquid-air interface, in which a chemical entity (droplets, particles) can be self-propped and provides artificial chemotactic motion in a gradient of concentration or temperature. In these systems the global and local Marangoni flows play important role in supporting the tactic motion of the entity. In this work, we provide a short description of existing methods utilizing the Marangoni flow to support tactic motion of an entity at the liquid-air interface by passive or active ways. We also present an alternative way to simulate fluid flow (Marangoni flow) based on dissipative particle dynamics.
