Iron Oxide/ Silicon Oxide/ Aluminium Oxide Core Shell

Insynthesis of Iron Oxide Silicon Oxide Aluminium Oxide Core Shell, the coating is important, as Iron Oxidehave several limitations in case of biomedical applications: a reactivity of iron oxides with blood, an aggregation at physiological blood pH (7.35 – 7.45). These problems are solved by coating iron oxides with Silica. Silica provides active interactions between its surface and H+ OH– ions at physiological pH making surface charged and electrostatic repulsion mechanism working. This phenomena prevents aggregation of Iron Oxide in a human blood, establishes colloidal stability. Also, silica is an inert and non-toxic material with high potential for functionalization with different ligands assigned to a wide range of biomedical applications.
