The remote heating of iron oxide nanoparticles in an alternating magnetic field is used to drive a thermoresponsive sol-gel block copolymer, Pluronic® F-127, through the upper phase transition temperature. This phase change triggers an accelerated release rate of a model drug. Actuation and return to baseline levels are demonstrated for multiple AMF doses.
