Turbulent mixing by microscopic self-assembled spinners

Abstract

A system for mixing particles that includes a liquid comprising inert particles and defining a liquid and air interface; magnetic microparticles suspended at the liquid and air interface; and a magnetic source configured to apply a uniaxial alternating magnetic field parallel to the liquid and air interface, wherein the uniaxial alternating magnetic field promotes a turbulent motion of the magnetic microparticles, which in turn promotes a diffusive motion of the inert particles.
