Non-equilibrium patterns are widespread in nature and often arise from the self-organization of constituents through nonreciprocal chemotactic interactions. In this study, we demonstrate how active oil-in-water droplet mixtures with predator-prey interactions can result a variety self-organized patterns. By manipulating physical parameters, diameter ratio number ratio, identify distinct classes within binary system, rationalize pattern formation, quantify motilities. Experimental results recapitulated numerical simulations using minimal computational model that solely incorporates steric repulsion among constituents. The time evolution is investigated chemically explained. We also investigate vary differing interaction strength by altering surfactant composition. Leveraging insights framework extended to ternary mixture composed multiple chasing pairs create directed hierarchical organization. Our findings rationalizable, be programmed system provide basis for exploration emergent organization higher order complexity colloids.

In this Account, we highlight our group’s efforts towards developing chemical frameworks for understanding active and interactive oil-in-water emulsions. How do the properties physical spatial organization of oil, water, surfactant combine to yield colloidal-scale properties? Our group tackles question by employing systematic studies behavior working across space oils surfactants link molecular structure behavior. The Account begins with an introduction self-propulsion single, isolated droplets how applying biases, such as a gravitation field or interfacially adsorbed particles, drop speeds can be manipulated. Next, illustrate that some attractive, well self-propulsive / repulsive, which does not fall in line current impact oil-filled micelle gradients on interfacial tensions. mechanisms micelles influence tensions non-equilibrium interfaces is poorly understood requires deeper understanding. Regardless, extend knowledge droplet motility design emulsions non-reciprocal predator-prey interactions describe dynamic self-organization arises from combination reciprocal between droplets. Finally, progress answering key questions surrounding processes remain answered. We hope principles governing help inform research tangential areas cell biology origin-of-life.
