Inspired by chasing-escaping behaviors of predator and swarming prey in nature, here we demonstrate a concept to create active micromotor systems from two species of passive microparticles with biomimetic predator-prey interactions. In this concept, the biomimetic predator-prey interactions are established in a binary particle system comprising the diffusiophoretic attractive microparticles (prey particles) and the diffusiophoretic repulsive ones (predator particles). In the absence of… 

Visible light-regulated BiVO4-based micromotor with biomimetic ‘predator-bait’ behavior

This work develops a light-powered BiVO4-based micromotor with self-propulsion and dynamic ‘predator-bait’ collective behavior, which is based on the photocatalytic reaction of Bi VO4 and has great potential in the field of organic pollutant degradation with enhanced apparent rate constant (0.076 min−1) which originates from the dynamic ’predators’ behavior.

Manipulation of paramagnetic microparticles can be exploited for drug delivery by manipulating a swarm of such particles and control its shape with a magnetic field so that it can elongate reversibly, split into smaller swarms and thus be guided through a maze with multiple parallel channels.

Reconfiguring active particles by electrostatic imbalance.

A general strategy to reconfigure active particles into various collective states by introducing imbalanced interactions is presented, and this strategy of asymmetry-driven active self-organization should generalize rationally to other active 2D and three-dimensional materials.
