"Magnetoelectric Nanomaterials and their Potential for Biomedical Applications"

Abstract :
Electric fields are ubiquitous throughout the body, playing important roles in a multitude of biological processes including angiogenesis, cell division, cell signaling, prenatal development, wound healing, and neural stimulation. An increased understanding of the role of electric fields in the body has led to the development of devices for biomedical applications that incorporate electromagnetic fields as an intrinsically novel functionality (e.g., bioactuators, biosensors, cardiac/neural electrodes, and tissues scaffolds). However, in the majority of the aforementioned devices an implanted power supply is necessary for operation, and therefore requires highly invasive procedures. Thus, the ability to apply electric fields in a minimally invasive manner to remote areas of the body remains a critical and unmet need. Here, we report on the potential of magnetoelectric-based composites to overcome this challenge. Magnetoelectric materials are capable of producing localized electric fields in response to an applied magnetic field, which the body is permeable to. To date, little to no work has examined the use of magnetoelectric materials for biomedical applications. Here, we present on the potential of magnetoelectric materials to be utilized in biomedical applications, with a focus on neuronal stimulation for regeneration purposes. This will be presented alongside current state-of-the-art for in vitro and in vivo electrical stimulation of cells and tissues. We will identify key challenges in this field, such as the synthesis and characterization of biocompatible magnetoelectric materials, challenges in experimental design, and opportunities for future research that would lead to the realization of magnetoelectric biomaterials and their applications.
