Role of supermagnetic nanoparticles in alzheimer disease

Nanoparticles are the major development of nanotechnology and used in different biomedical fields. The nanoparticles are in different forms such as metal, polymer, and composites. In the metal and metal oxide, nanoparticles are used as anticancer, antimicrobial, and in many neurological diseases. The magnetic nanoparticles play an important role in the diagnosis, especially the imaging techniques (magnetic imaging, magnetic resonance imaging MRI scanning) and many sensors and environmental remediation techniques. Recently, the nanoparticles were used in the neural stem cell detection and neurodegenerative diseases, especially the Alzheimer’s disease. We have very limited numbers of research articles in the area of magnetic nanoparticles in neurodegenerative diseases. In this chapter, we have elaborated the synthesis of magnetic nanoparticles using different plant extracts and microorganisms used for magnetic nanoparticles synthesis and characterization of the nanoparticles using different microscopic and spectroscopic techniques and biomedical applications of magnetic nanoparticles. Finally, the magnetic nanoparticles in the Alzheimer’s disease have been explained with graphical representations.
