One step (direct) and multisteps synthesis methods of metal and oxide nanoparticles are presented including both bottom-up and top-down procedures. Chemical methods involving the polyol process allows to get either isotropic or anisotropic nanoparticles. Nanowires, nanorods and dumbells can be generated either by heterogeneous nucleation or by using a template (mesoporous silica). Top-down procedures are illustrated by laser irradiation of immersed bulk targets (Ag, Au) which generates self-organized nanostructures or colloidal solutions. Laser irradiation of these colloidal solutions modifies the size distribution and the shape of nanoparticles. Bimetallic nanoparticles are generated from mixtures of monometallic colloidal solutions. Surface-mediated methods involving a host support and an invited phase are also presented. They lead to the formation of metal or oxide clusters and nanoparticles. The speciation of these entities is correlated with the observed catalytic performances.

Nanotechnology is a multidisciplinary branch of science which encompasses numerous diverse fields of science and technology, ranging from biomedical, pharmaceutical, agricultural, environmental, advanced materials, chemical science, physics, electronics, information technology, and so on. Physical and Chemical properties as a major advantages of Nanoparticles can be used in various applications from Industries to medicine. Besides, Magnetic nanoparticles for medical applications have been developed by many researchers. In recent decades, it has received attention by virtue of their potential for applications in different fields. Due to several advantages and widespread applications of magnetic Nanoparticles in biotechnology, medical, material science, engineering, and environmental areas, much attention has been paid to the synthesis of different kinds of Biomagnetic nanoparticles (BMNPs). Core-shell nanoparticles include of coated various materials like: biopolymers (Chitosan, PAA) and bioceramics (Hydroxyapatite) as a shell on top of them and different hard and soft materials like metal oxide (Iron oxide and Cob alt composite) as a core. Improved properties of core-shell nanoparticles like less cytotoxicity, increase biocompatibility, decrease in an interactions with biomolecules, increase physicochemical stability and sort of that, can be due to their use in biological applications. After reviewing several research and review articles and synthesis procedure of Iron based Bio-magnetic Nanoparticles (BMNPs), we should emphasize that, It can be used in different applications like magnetic resonance imaging (MRI), drug delivery systems (DDS), immunoassay, also specially in diagnosis and treatment of cancer via hyperthermia (heat therapy) method.

In this study, dextran-encrusted magnetic nanoclusters (DMNCs) were synthesized using a one-pot solution phase method for detection of atherosclerosis by magnetic resonance imaging. Pyrenyl dextran was used as a surfactant because of its electron-stabilizing effect and its amphiphilic nature, rendering the DMNCs stable and water-dispersible. The DMNCs were 65.6±4.3 nm, had a narrow size distribution, and were superparamagnetic with a high magnetization value of 60.1 emu/g. Further, they showed biocompatibility and high cellular uptake efficiency, as indicated by a strong interaction between dextran and macrophages. In vivo magnetic resonance imaging demonstrated the ability of DMNCs to act as an efficient magnetic resonance imaging contrast agent capable of targeted detection of atherosclerosis. In view of these findings, it is concluded that DMNCs can be used as magnetic resonance imaging contrast agents to detect inflammatory disease.
