  Self-assembly of particles at fluid-fluid interfaces is a widespread
phenomenon. Over time, researchers have explored various intrinsic and
extrinsic parameters to modulate and direct these processes. This review
article focuses on how external fields, specifically electric and magnetic
fields, can control the self-assembly of mesoscopic particles at interfaces. By
adjusting particle shape and size, attractive forces can be finely tuned.
Additionally, the strength and direction of external fields significantly
influence the final assembled structure. These systems offer promising
potential for innovative applications in drug delivery, catalysis, and other
transport phenomena.
