Abstract:The magnetic field-induced actuation of colloidal nanoparticles has enabled tremendous recent progress towards microrobots, suitable for a variety of applications including targeted drug delivery, environmental remediation or minimally invasive surgery. Further size reduction to the nanoscale requires enhanced control of orientation and locomotion to overcome dominating viscous properties. Here we demonstrate how the coherent precession of nanoscale hematite spindles can be controlled via dynamic magnetic fiel… Show more
