Abstract

We demonstrate how to dynamically tune the assembly of anisotropic colloidal particles adsorbed at fluid-fluid interfaces using dipolar capillary interactions. We exploit a previously discovered first-order phase transition and show how to spontaneously turn off these dipolar capillary interactions by exceeding a critical field strength, providing unprecedented control of the bottom-up fabrication of soft materials.
