Study finds advantages to iron nanoparticles for environmental clean up. specific advantages such as higher surface to volume ratio, higher thermal conductivity, and better lubricating properties than micro-sized additives (Kumar et al., 2018; Kumar et al., 2019a). Nano medicine is the preservation and im­provement of human health using molecular tools and molecular knowledge of the human body. This accounts for their increased use in the delivery of drugs. This brief review focuses on the design of nanomaterials that take advantage of PET. The disadvantages of the Nanotechnology are. But nanoparticles that conduct electricity, such as zinc oxide, titanium dioxide and antimony-doped tin oxide, can help disperse this charge. Despite several advantages of a biological synthesis approach for nanoparticles, the polydispersity of the nanoparticles formed remains a challenge. Nanoparticle-based drug delivery systems have considerable potential for treatment of tuberculosis (TB). Magnetic nanoparticles: Advantages of using, methods for preparation, characterization, application in pharmacy.
