Magnetic Nanodiscs Enable Remote Magnetomechanical Neural Stimulation

Magnetic nanomaterials in magnetic fields can serve as versatile transducers for remote interrogation of cell functions. In this study, we leveraged the transition from vortex to in-plane magnetization in iron oxide nanodiscs to modulate the activity …

Remote Magnetothermal Disruption of Amyloid-β Aggregates

Remotely triggered hysteretic heat dissipation by magnetic nanoparticles (MNPs) selectively attached to targeted proteins can be used to break up self‐assembled aggregates. This magnetothermal approach is applied to the amyloid‐β (Aβ) protein, which …
