    Functional Magnetic Nanoparticles: Synthesis, Characterization and Applications
    (Book Rivers, 2026) Priyanshu Verma, Syed Mohd Amir
    This chapter provides a comprehensive introduction to functional magnetic nanoparticles (MNPs), emphasizing their fundamental magnetic behavior, synthesis strategies, characterization techniques, and multidisciplinary applications. The discussion begins with the physics of nanoscale magnetism, including single-domain formation, superparamagnetism, magnetic anisotropy, and blocking temperature. Various synthesis approaches such as co-precipitation, thermal decomposition, hydrothermal, sol gel, and vapor-phase methods are presented, along with the importance of surface functionalization for enhancing stability and functionality. The chapter further reviews advanced characterization techniques including X- ray diffraction, electron microscopy, scattering methods, magnetometry, and thermal analysis for understanding structure property relationships. Finally, major applications of MNPs in spintronics, catalysis, environmental remediation, magnetic resonance imaging, targeted drug delivery, hyperthermia, bio-sensing, energy storage, and smart materials are highlighted. The chapter aims to provide a clear and interdisciplinary understanding of the scientific principles and technological significance of functional magnetic nanoparticles.
