The ical views on the magnetism of nanoparticles are considered. The bibliography includes 416 references bibliography includes 416 references. .

Preparation of silica coated cobalt ferrite magnetic nanoparticles for the purification of histidine-tagged proteins

“…Nanotechnology is the technology dealing with both single nano-objects and materials and devices based on them and with processes that take place in the nanometer range (Gubin, Koksharov, Khomutov, & Yu., 2005). Nanotechnology, a broad and interdisciplinary research field, involving engineering, chemistry, physiology, biology and more, has been growing exponentially in the past few years, showing great potential for several applications, (Jun, Seo, & Cheon, 2008) such as in materials development, biomedical sciences, electronics, optics, magnetism, energy storage, and electrochemistry ( Figure 1) (Safarik & Safarikova, 2002).…”

The research of finely dispersed iron powder moistening applying the pH–metry method

“…This oxide is characterized as hydrophilic. Moistening process occurs in accordance with external diffusion inhibition [13][14][15][16][17][18][19]. The causes of different behavior of haematite and magnetite during hydrolytic adsorption are thoroughly described in works [5][6][7].…”

Synthesis of ferromagnetic La1−x Sr x MnO3 nanoparticles by precipitation from diethylene glycol solution and their properties

“…For instance, using them for MRI permits increasing the image contrast [6]. The application of magnetic nanomaterials in drug delivery gives an opportunity to decrease the dosage of injected medicine [7], drug injection becomes local, and thus negative influence of toxic compounds on healthy tissues can be avoided [8]. It also should be mentioned that we could improve hyperthermia treatment of malignant tumors by using magnetic nanoparticles [9].…”
