An Overview of Magnetic Nanomaterials

Like every other nanomaterial (NM) or nanoparticles (NPs), magnetic nanomaterials (MNMs) or magnetic nanoparticles (MNPs), utilize bionanomaterials (BNMs), nanosized materials composed of various biological entities. MNMs are advanced materials that, once synthesized and characterized, can be used in solar cells, theragnostic nanomedicine, drug and gene delivery agents, tissue engineering, biosafety and bioregulation aspects, pathogen combat, wastewater treatment, soil decontamination, detection, sensing, and monitoring of heavy metals, dyes, toxic gases, and so on. Several MNMs or MNPs have been utilized for applications in biomedical, agriculture, and environmental (atmospheric, aquatic, and terrestrial) fields. Hence, this introductory chapter presents a summarized highlight of the various synthesis and characterization techniques of MNMs, along with the various applications and potentialities of MNMs both in the biomedical, agricultural, and environmental fields, as well as catalytic processes which is the major aim of this book. Also, some outstanding prospects of MNMs or MNPs in biomedical, agricultural, and environmental applications are highlighted in the conclusion section.
