Significance The ability to control and separate individual active particles in fluid layers is a challenge in biological and engineering contexts as well as a basic problem of controlled self-assembly. Here we place spinners in a wave-driven matrix of vortices, akin to optical lattices. The results offer a method of manipulating spinning particles within a wave-produced flow. Spinners can be confined on stable orbits, trapped inside, or released from the liquid metamaterial cells without solid boundaries and can be used to carry biological or chemical agents within the vortex lattice.
