Soluto-inertial phenomena: Designing long-range, long-lasting, surface-specific interactions in suspensions
Abstract
Liquid suspensions of micron-scale particles and drops play a ubiquitous role in a broad spectrum of materials of central importance to modern life. A suite of interactions has long been known and exploited to formulate such suspensions; however, all such interactions act over less than a micron in water—and often much less. Here we present a concept to design and engineer nonequilibrium interactions in suspensions, which are particle surface-dependent, may last for hundreds of seconds, and extend hundreds of times farther than is currently possible. The conceptual versatility of the results presented here suggests new capabilities for manipulating suspensions, sorting particles, and synthesizing novel materials and particles.
