This paper presents the unitary and controlled synthesis of nanostructures of the type Fe3O4-n[SiO1.5-(CH2)3(NH2)]-Snθ [Fe3O4 = magnetic core; n[SiO1.5-(CH2)3(NH2)] = coating layer; -NH2 = layer made up of groups which play an important part in biochemical interface; Snθ = exterior layer of biochemical cross-linked molecules]. The purpose of obtaining these nanostructures is to fix Fe3O4-n[SiO1.5-(CH2)3(NH2)]-Snθ on microorganism surface through covalent chemical bounds in order to determine them in magnetic field, as a function of the mass and volume of the microorganisms attached to the
nanostructures. The nanocomposite materials with physical and chemical features induced in a controlled way in the basic physical structure in order to handle in a controlled manner the host structures, constitute a research field of current interest. The nanostructures we have drawn up are also important in fields connected to chemistry, such as:
selective/unselective chemical separation, molecular macrocomplexes labeling, chemical/biological detection media and others.
