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.en-USFe3O4-SiO2-NH2 core-shell nanoparticleSuperparamagneticCross-linked moleculeArticle
