Fig. 7. Active transport in spinner lattices.

(A) MSD of an inert particle of 500 μm diameter at f_H = 45 Hz. The blue and red lines represent the ballistic (∝Δt²) and normal diffusion regime (∝Δt), respectively. Inset: A typical trajectory of the passive bead transported in the active spinner lattice. (B) MSD and an example trajectory of a transported passive particle as obtained in simulations for a passive particle of diameter σ at ρ = 0.0108 σ⁻² (see movie S6). (C) Active diffusion coefficient as a function of the magnetic field frequency, f_H. The experiments were performed at ρ = 0.006 σ⁻².
