Nano-Magnetism for Precision Neuroscience: Biohybrid Magnetoelectric Nanocarriers as Next-Generation Neural Drug Delivery Platforms.

Abstract

Neuroscience is making tremendous progress toward precision medicine, with nanotechnology playing a critical role in overcoming hurdles to successful brain medication delivery. Nano magnetism, namely biohybrid magnetoelectric nanocarriers (MENs), has emerged as a potential method for targeted and non-invasive medication delivery in neurological illnesses. These nanocarriers possess magnetoelectric properties, enabling stimulus-responsive drug release that is externally controlled. This allows for precise targeting across the blood-brain barrier (BBB), with exceptional spatial and temporal resolution. MENs can deliver neurotherapeutics deep into brain regions by combining magnetic guidance with electrical stimulation, thereby improving treatment outcomes for conditions such as Alzheimer's, Parkinson's, epilepsy, and glioblastoma. Furthermore, their biohybrid nature, which is accomplished by functionalizing nanocarriers with biocompatible coatings, peptides, or membranes produced from neural cells, increases biostability, decreases immune response, and improves neuron targeting. This review investigates the underlying concepts of magnetoelectric nanocarriers, production processes, and interactions with brain tissue. It dives deeper into recent advances in precision neural drug delivery, including the effect of external magnetic and electric fields on regulated drug release, neurostimulation, and neuromodulation. While MENs have tremendous promise, long-term biocompatibility, precise control systems, and regulatory restrictions continue to impede clinical translation. Future research should concentrate on enhancing nanocarrier design, increasing targeting efficiency, and undertaking large-scale preclinical and clinical trials. Magnetoelectric nanocarriers have the potential to transform non-invasive neurotherapeutics by bridging the gap between nano magnetism and neuroscience, resulting in safer and more successful treatment paradigms for complex brain illnesses.
