Novel coil-less room-temperature resettable magnetic-bead manipulation by using thermomagnetic tracks

[Display omitted] •We demonstrate a novel thermomagnetic-track-guided magnetic bead manipulation.•Cooling to 5℃, tracks become ferromagnetic and thus can guide the bead motion.•Heating to 50 °C, tracks become paramagnetic and thus cannot guide the bead motion.•This achieves a coil-less room-temperat...
