Phoretic colloids close to and trapped at fluid interfaces

The active motion of phoretic colloids leads them to accumulate at boundaries and interfaces. Such an excess accumulation, with respect to their passive counterparts, makes the dynamics of phoretic colloids particularly sensitive to the presence of boundaries and pave new routes to externally control their single particle as well as collective behavior. Here we review some recent theoretical results about the dynamics of phoretic colloids close to and adsorbed at fluid interfaces in particular highlighting similarities and differences with respect to solid-fluid interfaces.

Automated summary

The active motion of phoretic colloids causes them to accumulate at boundaries and interfaces, making their dynamics particularly sensitive to these interactions and offering new ways to control their behavior. Recent theoretical studies on phoretic colloids near fluid interfaces highlight similarities and differences compared to solid-fluid interfaces.
