Abstract
Magnetic nanoparticles (MNs) can be broadly described as nanoparticles that can be controlled by magnetic fields. Magneto‐electric nanoparticles (MENs), on the other hand, do not react exothermically to the applied magnetic field and thereby are more energy efficient. This chapter discusses MENs, their structural properties, and their application. It explains how MENs have better energy efficiency and less heat dissipation, making them a better alternative for target drug delivery. The chapter reviews three experiments. The first experiment deals with the application of MENs in the treatment of ovarian cancer. The second experiment relates to the delivery of drugs for treatment of HIV‐1 reservoirs, and the third explains how magneto‐electric (ME) spin can be used to stimulate the brain. The chapter examines how bioceramics exhibit selective targeting properties, and explores the integration of MNs with bioceramic silica to form mesophoric structures.
