Magnetic nanomaterials‐mediated neuromodulation

Abstract Researchers have leveraged magnetic nanomaterials (MNMs) to explore neural circuits and treat neurological diseases via an approach known as MNMs‐mediated neuromodulation. Here, the magneto‐responsive effects of MNMs to an external magnetic field are manipulated to activate or inhibit neuronal cell activity. In this way, MNMs can serve as a nano‐mediator, by converting electromagnetic energy into heat, mechanical force/torque, and an electrical field at nanoscale. These physicochemical effects can stimulate ion channels and activate precise signaling pathways involved in neuromodulation. In this review, we outline the various ion channels and MNMs that have been applied to MNMs‐mediated neuromodulation. We highlight the recent advances made in this technique and its potential applications, and then discuss the current challenges and future directions of MNMs‐mediated neuromodulation. Our aim is to reveal the potential of MNMs to treat neurological diseases in the clinical setting.
